# Изменения
|
||||||
|
|
||||||
|
## v1.0.0 — 2026-10-01
|
||||||
|
|
||||||
|
Первый выпуск.
|
||||||
|
|
||||||
|
**Прошивка моста BL616** (`tang25k_debugger_bl616.bin`, версия 1.0.0)
|
||||||
|
|
||||||
|
* Составное USB-устройство `1209:C0CA`: DirtyJTAG v3 (WinUSB ставится сам,
|
||||||
|
без Zadig) + CDC-ACM UART к пинам FPGA B3/C3; работают одновременно.
|
||||||
|
* UART от 300 бод до 20 Мбод, 5–8 бит, чётность none/odd/even, 1/1.5/2
|
||||||
|
стоп-бита. Проверено 9600 … 12 Мбод в обе стороны без потерь, поток
|
||||||
|
FPGA → ПК 10 Мбод непрерывно 30 с без ошибок.
|
||||||
|
* JTAG до 30 МГц, длинные сдвиги через аппаратный SPI. Загрузка GW5A-25 в
|
||||||
|
SRAM ≈ 2 с при 6 МГц, запись во флеш-память FPGA с проверкой ≈ 8 с.
|
||||||
|
* Обход особенностей BL616: зависание приёмника UART при смене скорости
|
||||||
|
посреди байта, запись `usbser.sys` без завершающего ZLP, потеря ZLP на IN.
|
||||||
|
* Переход в загрузчик без перемычки: открыть COM-порт моста на 1234 бод или
|
||||||
|
держать S3 при подключении USB.
|
||||||
|
|
||||||
|
Пишется вместе с загрузчиком Sipeed: `bl616_bootloader_0x20000_nano20k_signed.bin`
|
||||||
|
по адресу `0x0`, прошивка моста по адресу `0x20000`. Откат —
|
||||||
|
`bl616_fpga_partner_25kDock.bin` (штатная Sipeed 2025030317) по адресу `0x0`.
|
||||||
|
|
||||||
|
**Программатор TangProgrammer** (Windows 10/11 x64, .NET Framework 4)
|
||||||
|
|
||||||
|
* FPGA: загрузка `.fs` в SRAM и во флеш-память, автозагрузка при пересборке
|
||||||
|
в Gowin IDE, перезапуск из флеш-памяти.
|
||||||
|
* Флеш-память FPGA: определение микросхемы, резервная копия с двойным чтением,
|
||||||
|
запись `.bin`/`.fs`, стирание.
|
||||||
|
* Прошивка моста BL616 и возврат штатной прошивки Sipeed.
|
||||||
|
* Светлая и тёмная тема.
|
||||||
|
|
||||||
|
**Тестовые битстримы** для GW5A-25: `loopback.fs` (петля UART) и `stream.fs`
|
||||||
|
(поток 10 Мбод) — к `tests\uart_loopback_test.py` и `tests\uart_stream_test.py`.
|
||||||
|
|
||||||
|
**Ограничения:** Gowin Programmer с этой прошивкой не работает (только
|
||||||
|
openFPGALoader); `--unprotect-flash` с флеш-памятью XTX на плате не использовать.

# Прошивка отладчика BL616 для Tang Primer 25K
|
||||||
|
|
||||||
|
Замена штатной прошивки встроенного отладчика (BL616) на плате **Sipeed Tang
|
||||||
|
Primer 25K Dock**. Вместо эмуляции FT2232 плата становится составным
|
||||||
|
USB-устройством из двух независимых функций:
|
||||||
|
|
||||||
|
| Функция | Что это | Драйвер Windows |
|
||||||
|
|---|---|---|
|
||||||
|
| **JTAG** | DirtyJTAG v3 (`1209:C0CA`, интерфейс 0) для `openFPGALoader -c dirtyJtag` | WinUSB, ставится сам (MS OS 2.0) — Zadig не нужен |
|
||||||
|
| **UART** | CDC-ACM, обычный COM-порт к пинам FPGA **B3/C3** | встроенный `usbser.sys` |
|
||||||
|
|
||||||
|
Оба работают одновременно: можно грузить битстрим, не закрывая терминал.
|
||||||
|
|
||||||
|
## Скачать
|
||||||
|
|
||||||
|
Готовые файлы — в [релизах](http://gitea.vector.ru/Gromov_IA/BL616-firmware/releases):
|
||||||
|
|
||||||
|
| Файл | Что это |
|
||||||
|
|---|---|
|
||||||
|
| `TangProgrammer-<версия>-win64.zip` | **программатор с окном** — распаковать и запустить, внутри всё нужное (openFPGALoader, BLFlashCommand, прошивки моста) |
|
||||||
|
| `TangProgrammer.exe` | только программа — для клона этого репозитория (рядом должна быть папка `tools\`) |
|
||||||
|
| `tang25k_debugger_bl616.bin` | прошивка моста, пишется по адресу `0x20000` |
|
||||||
|
| `bl616_bootloader_0x20000_nano20k_signed.bin` | загрузчик Sipeed, пишется по адресу `0x0` вместе с прошивкой моста |
|
||||||
|
| `bl616_fpga_partner_25kDock.bin` | штатная прошивка Sipeed (`0x0`) — для отката |
|
||||||
|
| `fpga_test_bitstreams-GW5A-25.zip` | тестовые битстримы `loopback.fs` и `stream.fs` для проверки UART |
|
||||||
|
| `SHA256SUMS.txt` | контрольные суммы |
|
||||||
|
|
||||||
|
Чтобы только пользоваться платой, достаточно архива `TangProgrammer-…-win64.zip`:
|
||||||
|
он прошивает и мост (один раз), и FPGA. SDK и сборка не нужны.
|
||||||
|
|
||||||
|
## Что получилось (проверено на плате)
|
||||||
|
|
||||||
|
| | |
|
||||||
|
|---|---|
|
||||||
|
| UART, скорости | любые от 300 бод до 20 Мбод (делитель от 160 МГц); проверено 9600 … **12 Мбод в обе стороны без единой потери** |
|
||||||
|
| UART, формат | 5–8 бит, чётность none/odd/even, 1 / 1.5 / 2 стоп-бита |
|
||||||
|
| UART, поток FPGA → ПК | 10 Мбод непрерывно (1 МБ/с) 30 с — 0 ошибок; точность частоты подтверждена генератором FPGA |
|
||||||
|
| UART, ПК → FPGA | управление потоком по USB (NAK), данные не теряются при любой скорости |
|
||||||
|
| UART, буфер | кольцевой DMA-буфер 64 КБ на приём, 16 КБ на передачу |
|
||||||
|
| JTAG | `--detect` за ~40 мс; загрузка GW5A-25 в SRAM ≈ 2 с при 6 МГц |
|
||||||
|
| JTAG, частота | до 30 МГц; длинные сдвиги идут через аппаратный SPI BL616 |
|
||||||
|
|
||||||
|
Стресс-тест: сотни прогонов петли с произвольными скоростями и объёмами — без ошибок.
|
||||||
|
|
||||||
|
## Как это устроено
|
||||||
|
|
||||||
|
**Загрузка.** У BL616 на этих платах прожжён eFuse: ROM запускает с адреса
|
||||||
|
`0x0` только образ, зашифрованный ключом Sipeed. Поэтому по `0x0` пишется
|
||||||
|
загрузчик Sipeed (`bin/bl616_bootloader_0x20000_nano20k_signed.bin`,
|
||||||
|
выпущен Sipeed для Nano 20K; ключ у всех плат серии общий — проверено
|
||||||
|
сравнением шифротекстов штатных прошивок), а он безусловно передаёт
|
||||||
|
управление нашей прошивке по `0x20000`.
|
||||||
|
|
||||||
|
**Распиновка BL616** (схема `Tang_25K_60033`):
|
||||||
|
|
||||||
|
| Сигнал | BL616 | FPGA |
|
||||||
|
|---|---|---|
|
||||||
|
| TMS | GPIO0 | B1 |
|
||||||
|
| TCK | GPIO1 | C1 |
|
||||||
|
| TDO | GPIO2 (он же BOOT) | A2 |
|
||||||
|
| TDI | GPIO3 | A3 |
|
||||||
|
| UART TX (ПК → FPGA) | GPIO11 | **B3** (`uart_rx` в FPGA) |
|
||||||
|
| UART RX (FPGA → ПК) | GPIO10 | **C3** (`uart_tx` в FPGA) |
|
||||||
|
| светодиод LED5 | GPIO20 | — |
|
||||||
|
| кнопка S3 | GPIO12 | — |
|
||||||
|
|
||||||
|
Кварц BL616 на Dock — **26 МГц** (а не 40 МГц, как в SDK по умолчанию).
|
||||||
|
|
||||||
|
**Почему штатный UART работал плохо, а этот нет** — коротко о найденных
|
||||||
|
особенностях BL616, которые обходит прошивка:
|
||||||
|
|
||||||
|
* приёмник UART BL616 намертво зависает, если сменить скорость посреди
|
||||||
|
приходящего байта (типичная ситуация: FPGA уже шлёт данные, а терминал
|
||||||
|
открывается на другой скорости); сброс бита EN, как делает SDK, не
|
||||||
|
помогает — прошивка делает полный программный сброс блока UART1 при
|
||||||
|
каждой реальной смене параметров и держит сторожевой таймер;
|
||||||
|
* `usbser.sys` пишет порциями, кратными 512 байтам, без завершающего
|
||||||
|
нулевого пакета — приём ведётся строго по одному пакету;
|
||||||
|
* нулевой пакет (ZLP) на IN, запрошенный пока прошлый пакет ещё в FIFO,
|
||||||
|
теряется — передачи к ПК всегда заканчиваются коротким пакетом.
|
||||||
|
|
||||||
|
## Установка (один раз)
|
||||||
|
|
||||||
|
1. Закройте Gowin Programmer / BouffaloLabDevCube, если они открыты.
|
||||||
|
2. Отключите USB-C (JTAG/UART) от платы.
|
||||||
|
3. Замкните тестовые точки **TDO** и **3V3** (нижняя сторона Dock, левый
|
||||||
|
верхний угол), подключите USB, разомкните. Появится устройство
|
||||||
|
«Bouffalo CDC DEMO» (COM-порт).
|
||||||
|
4. Прошейте мост одним из способов:
|
||||||
|
* **TangProgrammer** из релиза: вкладка «Прошивка моста (BL616)» →
|
||||||
|
«Записать прошивку моста»;
|
||||||
|
* из исходников (нужны `scripts\setup.ps1` и `scripts\build.ps1`):
|
||||||
|
```powershell
|
||||||
|
.\scripts\flash.ps1
|
||||||
|
```
|
||||||
|
*(пишет загрузчик Sipeed из `bin\` и собранную прошивку моста
|
||||||
|
`build\build_out\tang25k_debugger_bl616.bin`)*;
|
||||||
|
* вручную, BouffaloLabDevCube или BLFlashCommand: файлы из релиза,
|
||||||
|
`bl616_bootloader_0x20000_nano20k_signed.bin` по адресу `0x0` и
|
||||||
|
`tang25k_debugger_bl616.bin` по адресу `0x20000`.
|
||||||
|
5. Переподключите USB. Появятся «DirtyJTAG» и новый COM-порт.
|
||||||
|
|
||||||
|
Перед первой прошивкой стоит сохранить полный дамп флеш-памяти BL616
|
||||||
|
(плата в загрузчике, как в шаге 3):
|
||||||
|
```powershell
|
||||||
|
.\third_party\bouffalo_sdk\tools\bflb_tools\bouffalo_flash_cube\BLFlashCommand.exe --interface=uart --baudrate=2000000 --port=COMxx --chipname=bl616 --cpu_id= --flash --read --start=0x0 --len=0x400000 --file=backup\flash_full_4M.bin
|
||||||
|
```
|
||||||
|
Папка `backup\` в git не попадает.
|
||||||
|
|
||||||
|
## Обновление прошивки
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
.\scripts\build.ps1
|
||||||
|
.\scripts\flash.ps1
|
||||||
|
```
|
||||||
|
`flash.ps1` сам переводит работающую прошивку в загрузчик (открывает её
|
||||||
|
COM-порт на «магической» скорости **1234 бод**) и прошивает. После записи
|
||||||
|
**переподключите USB** — флаг «загрузиться в ISP» живёт до снятия питания.
|
||||||
|
|
||||||
|
Другие способы попасть в загрузчик: держать **S3** при подключении USB
|
||||||
|
(если эта прошивка уже стоит) или перемычка TDO→3V3 (работает всегда).
|
||||||
|
|
||||||
|
## Возврат штатной прошивки Sipeed
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
.\scripts\flash.ps1 -Restore
|
||||||
|
```
|
||||||
|
(или в TangProgrammer: «Вернуть штатную прошивку Sipeed»). Пишет `bin/bl616_fpga_partner_25kDock.bin` (версия 2025030317, sha256
|
||||||
|
`1be5c1f9…aacd`) — ровно то, что стояло на плате.
|
||||||
|
|
||||||
|
## Программатор с окном: `TangProgrammer.exe`
|
||||||
|
|
||||||
|
Замена Gowin Programmer поверх openFPGALoader, без консоли. Готовая программа —
|
||||||
|
архив `TangProgrammer-…-win64.zip` из релиза; в клоне репозитория её собирает
|
||||||
|
`.\scripts\build_gui.ps1` (появляется `TangProgrammer.exe` в корне, рядом с
|
||||||
|
`tools\`). Ничего ставить не нужно (.NET Framework 4 есть в Windows). Вверху окна — состояние моста
|
||||||
|
(подключён / загрузчик BL616 / штатная прошивка / нет платы), оно
|
||||||
|
обновляется само при подключении USB.
|
||||||
|
|
||||||
|
**Вкладка «FPGA»**
|
||||||
|
* битстрим `.fs` выбирается кнопкой «Обзор…» (Ctrl+O), из списка последних или
|
||||||
|
перетаскиванием в окно; под полем — модель FPGA из файла, размер и время
|
||||||
|
сборки (предупреждение, если файл собран не для GW5A-25);
|
||||||
|
* «Загрузить в SRAM» (F5) — до отключения питания; «Записать во Flash» — во
|
||||||
|
внешнюю флеш-память FPGA, с проверкой;
|
||||||
|
* «Загружать в SRAM автоматически, когда файл пересобран» — для работы вместе с
|
||||||
|
Gowin IDE: после каждой сборки новый `.fs` сразу попадает в FPGA;
|
||||||
|
* «Определить FPGA», «Перезапуск из Flash» (FPGA заново грузится из своей
|
||||||
|
флеш-памяти, как после включения питания).
|
||||||
|
|
||||||
|
**Вкладка «Флеш-память FPGA»** — определение микросхемы (на этой плате XTX,
|
||||||
|
JEDEC `0B4017`, 8 МБ), резервная копия в `.bin` (первый 1 МБ с конфигурацией
|
||||||
|
или вся микросхема; по умолчанию читается дважды и сравнивается), запись
|
||||||
|
`.bin`/`.fs` во флеш (пустой хвост 0xFF не пишется) и стирание всей микросхемы.
|
||||||
|
Время на этой плате: запись `.fs` с проверкой ≈ 8 с, копия 1 МБ ≈ 3 с на одно
|
||||||
|
чтение, стирание ≈ 13 с.
|
||||||
|
|
||||||
|
**Вкладка «Прошивка моста (BL616)»** — то же, что `scripts\flash.ps1`: записать
|
||||||
|
прошивку моста или вернуть штатную Sipeed.
|
||||||
|
|
||||||
|
Справа вверху — тема: как в Windows, светлая или тёмная. Настройки хранятся в
|
||||||
|
`%LOCALAPPDATA%\Tang25kProgrammer\settings.ini`. Пересборка программы:
|
||||||
|
`.\scripts\build_gui.ps1` (исходники — в `gui\`).
|
||||||
|
|
||||||
|
Если запись во флеш-память FPGA прервалась с ошибкой, программа сама повторяет
|
||||||
|
её один раз: недописанная флеш-память означает, что FPGA не загрузится при
|
||||||
|
включении.
|
||||||
|
|
||||||
|
**На другой компьютер** — архив из релиза или свой:
|
||||||
|
`.\scripts\make_portable.ps1` собирает `dist\TangProgrammer\` и
|
||||||
|
`dist\TangProgrammer.zip` (≈ 14 МБ) — программа, openFPGALoader, BLFlashCommand
|
||||||
|
(только exe и `chips\` вместо 238 МБ папки SDK), прошивки моста и памятка
|
||||||
|
`README.txt`. Распаковать в любую папку, куда можно писать (не в Program Files),
|
||||||
|
и запустить `TangProgrammer.exe`. Нужна Windows 10/11 x64; драйверы для платы
|
||||||
|
Windows ставит сама.
|
||||||
|
|
||||||
|
## Использование из консоли
|
||||||
|
|
||||||
|
JTAG — нужен **openFPGALoader ≥ 1.1.0** (в 1.1.0 исправлена работа DirtyJTAG
|
||||||
|
с GW5A). Готовая сборка для Windows лежит в `tools\openFPGALoader\bin`.
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
$ofl = ".\tools\openFPGALoader\bin\openFPGALoader.exe"
|
||||||
|
& $ofl -c dirtyJtag --detect # GW5A-25, idcode 0x0001281b
|
||||||
|
& $ofl -c dirtyJtag design.fs # загрузить битстрим в SRAM (до отключения питания)
|
||||||
|
& $ofl -c dirtyJtag --freq 15M design.fs # загрузить в SRAM быстрее
|
||||||
|
& $ofl -c dirtyJtag -f design.fs # прошить битстрим во внешнюю флеш-память FPGA (навсегда)
|
||||||
|
& $ofl -c dirtyJtag --dump-flash --file-size 1048576 copy.bin # копия первого 1 МБ флеш-памяти FPGA
|
||||||
|
& $ofl -c dirtyJtag -f copy.bin # записать образ обратно (с адреса 0)
|
||||||
|
& $ofl -c dirtyJtag --bulk-erase # стереть всю флеш-память FPGA
|
||||||
|
```

||||||
|
`--unprotect-flash` с этой микросхемой флеш-памяти не использовать: её нет в
|
||||||
|
справочнике openFPGALoader 1.1.1, и эта функция на ней падает. Защита записи
|
||||||
|
(биты BP) на плате и так снята.
|
||||||
|
|
||||||
|
UART — любой терминал или pyserial на появившемся COM-порту, скорость и
|
||||||
|
формат задаются как обычно. При открытии порта (DTR=1) накопленные за время
|
||||||
|
простоя данные сбрасываются, как у FTDI.
|
||||||
|
|
||||||
|
**Gowin Programmer эта прошивка не поддерживает** (он работает только с FTDI).
|
||||||
|
Для него — `flash.ps1 -Restore`.
|
||||||
|
|
||||||
|
## Сборка из исходников
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
.\scripts\setup.ps1 # Bouffalo SDK v2.3.16 + тулчейн T-Head в third_party\
|
||||||
|
.\scripts\build.ps1 # build\build_out\tang25k_debugger_bl616.bin
|
||||||
|
```
|
||||||
|
Если проект лежит на сетевом диске, который смотрит на эту же машину
|
||||||
|
(например `D:` → `\\PC\Projects`), скрипты сами собирают по локальному пути
|
||||||
|
— через SMB сборка в десятки раз медленнее.
|
||||||
|
|
||||||
|
## Тесты
|
||||||
|
|
||||||
|
`fpga_test\` — два тестовых проекта Gowin (готовые `.fs` есть в релизе):
|
||||||
|
|
||||||
|
* `loopback` — `uart_tx = uart_rx`, петля на любой скорости;
|
||||||
|
* `stream` — FPGA сама шлёт счётчик на ровно 10 Мбод.
|
||||||
|
|
||||||
|
Сборка — из папки проекта, например:
|
||||||
|
```powershell
|
||||||
|
cd fpga_test\loopback; & C:\Gowin\Gowin_V1.9.12_x64\IDE\bin\gw_sh.exe build.tcl; cd ..\..
|
||||||
|
```
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
& $ofl -c dirtyJtag fpga_test\loopback\impl\pnr\loopback.fs
|
||||||
|
python tests\uart_loopback_test.py --port COM14
|
||||||
|
& $ofl -c dirtyJtag fpga_test\stream\impl\pnr\stream.fs
|
||||||
|
python tests\uart_stream_test.py --port COM14 --seconds 30 --switches 10
|
||||||
|
```
|
||||||
|
|
||||||
|
## Выпуск релиза
|
||||||
|
|
||||||
|
1. Поднять `FW_VERSION_STR` в `src/sys.h` и описать изменения в `CHANGELOG.md`.
|
||||||
|
2. Собрать прошивку и тестовые битстримы, затем файлы релиза:
|
||||||
|
```powershell
|
||||||
|
.\scripts\build.ps1
|
||||||
|
.\scripts\make_release.ps1 # dist\release\v<версия>\ + SHA256SUMS.txt
|
||||||
|
```
|
||||||
|
3. Закоммитить, поставить тег и отправить:
|
||||||
|
```powershell
|
||||||
|
git tag -a v1.0.0 -m "v1.0.0"
|
||||||
|
git push origin main v1.0.0
|
||||||
|
```
|
||||||
|
4. Опубликовать релиз с файлами — нужен токен Gitea с правом
|
||||||
|
`write:repository` (Настройки → Приложения → Создать токен):
|
||||||
|
```powershell
|
||||||
|
$env:GITEA_TOKEN = "<токен>"
|
||||||
|
.\scripts\publish_release.ps1
|
||||||
|
```
|
||||||
|
Или вручную: «Релизы» → «Новый релиз» → тег, текст из `CHANGELOG.md`,
|
||||||
|
файлы из `dist\release\v<версия>\`.
|
||||||
|
|
||||||
|
## Ограничения
|
||||||
|
|
||||||
|
* Gowin Programmer не работает (только openFPGALoader).
|
||||||
|
* Чётность mark/space не поддерживается аппаратно (передаётся как «нет»).
|
||||||
|
* DTR/RTS и BREAK не выведены на FPGA — на плате нет таких линий.
|
||||||
|
* Нулевой пакет на JTAG-IN не отправляется: клиенты DirtyJTAG читают ответ
|
||||||
|
известной длины.

||||||
|

||||||

Tang Primer 25K — программатор (переносная версия)
|
||||||
|
====================================================
|
||||||
|
|
||||||
|
Запуск: TangProgrammer.exe, двойной щелчок. Устанавливать ничего не нужно.
|
||||||
|
|
||||||
|
Требования
|
||||||
|
----------
|
||||||
|
* Windows 10 или 11, 64-бит (.NET Framework 4.8 в них уже есть).
|
||||||
|
* Папку целиком держите в любом месте, куда можно писать (рабочий стол,
|
||||||
|
D:\...), но не в Program Files: программа прошивки моста создаёт файлы
|
||||||
|
рядом с собой.
|
||||||
|
* Gowin IDE на этом компьютере нужна только для сборки своих .fs.
|
||||||
|
|
||||||
|
Драйверы
|
||||||
|
--------
|
||||||
|
Ставить ничего не нужно. При первом подключении платы Windows сама установит
|
||||||
|
WinUSB для JTAG («DirtyJTAG») и драйвер COM-порта UART — подождите 10–30 секунд.
|
||||||
|
Прошивка моста хранится в самой плате (в BL616), переносить её не нужно.
|
||||||
|
|
||||||
|
Если архив скачан из интернета или пришёл почтой
|
||||||
|
-----------------------------------------------
|
||||||
|
До распаковки: правой кнопкой по zip → «Свойства» → отметить «Разблокировать»
|
||||||
|
→ OK. Иначе Windows может показать «Система Windows защитила ваш компьютер»
|
||||||
|
(программа не подписана) — тогда «Подробнее» → «Выполнить в любом случае».
|
||||||
|
|
||||||
|
Что внутри
|
||||||
|
----------
|
||||||
|
TangProgrammer.exe сама программа
|
||||||
|
tools\openFPGALoader\ openFPGALoader 1.1.1: загрузка FPGA, флеш-память FPGA
|
||||||
|
tools\bouffalo_flash_cube\ BLFlashCommand — только для вкладки «Прошивка моста»
|
||||||
|
firmware\, *.ini прошивка моста, загрузчик и штатная прошивка Sipeed
|
||||||
|
(тоже только для вкладки «Прошивка моста»)
|

пользователя в %LOCALAPPDATA%\Tang25kProgrammer.
