If DFU_SEAL_LEVEL != 0 i recive state(10) = dfuERROR, status(4) = Memory erase function failed.
What i do wrong ?

Can't reproduce with my STM32F103C8T6.
Do you cycle the power of the MCU after flashing bootloader?
Are there OK with RDP=0?
PS. Don't specify flash address to the dfu-util. This is DFU, not a DfuSe!

After flash i do power cycle. Dmesg empty.
Try several times , try enter to booloader. same usb devise absent.
Manualy set rdp =1 via st-link

i get new usb device, but some different

I was checked STM32F103 errata sheets and I have no more ideas, but I found one strange thing.
From 1st message.

Found DFU: [0483:df11] ver=0100, devnum=59, cfg=1, intf=0, path="1-1", alt=0, name="@internal Flash /0x08002000/56*1Kg", serial="9488CE25"

From 2nd message:

[68978.116402] usb 3-1: Product: Bootloader
[68978.116408] usb 3-1: Manufacturer: Cdi.biz.ua
[68978.116414] usb 3-1: SerialNumber: 5A0DF47F

The different serial numbers. Was it the same chip? If yes, it must be something wrong with MCU. "SerialNumber" string descriptor is auto-generated (FNV1A32) from the factory programmed 96-bit chip UID. It must be the same on the same chip.

no , different, first from home second i test from work

As i understand it goes the following sequence
setup pins ......

if DFU_SEAL_LEVEL 0 tcheck is rdp on
if rdp=0 turn read out protection and restart.

but itself bootloader not turn on rdp !!!

I found problem
It is a very very china cpu. Original stm32f103 work fine. I think need add disclaimer about non original stm processors
in my case it is I found a small logo cks ...

i see some code difference, but must work , i don't understand why code not worked

Is this code work well with fake F103? I see only two differences with my code. (stm32f103.S#L401)

  1. Using a read-modify-write instead of direct-write for the FLASH->CR. It may affect "Reserved" bitfields that can actually be in use.
  2. Set FLASH->CR to the LOCK state before issuing an NVIC reset.

yes this code work


   FLASH_Unlock();
  FLASH_ReadOutProtection(0x33CC);
  nvic_sys_reset();

worked too

@dmitrystu Откровенно говоря я так не понял что не хватает и почему работает загрузчик STM32duino-bootloader при установленной защите а ваш нет, в то-же время судя по даташиту надо именно биты менять а не байт целиком, пробовал повторить алгоритм отсюда https://github.com/rogerclarkmelbourne/STM32duino-bootloader/blob/df689808b6030280480c0d151ee9c552ecf6b405/hardware.c#L330 но результат нулевой, может я криво код написал , не знаю , пока идеи закончились

Как я понимаю, при использовании китайского клона F103 возникает ошибка стирания страницы при записи во флеш, причем независимо от того, каким образом был установлен RDP: бутлоадером, пользовательским кодом или через stprog. Сам RDP устанавливается корректно. Так ? Попробую найти такой клон.
PS. Посмотрел по ссылке, там используется макрос SETREG который тоже пишет напрямки а не read-modify-write. Но у него не прооверяется бит EOP в FLASH->SR после стирания. Он по ходу вообще его не проверяет. Го в пм по этому вопросу.
