STM32F103C8T6 device descriptor error

[jeanthom]

Hi Kim, Your issue is very concerning. To help me debug your issue, could you please report/try the following things: 1. Report the git hash of DirtyJTAG if you've build it from source, or the release version of you were using the release builds. 2. Report all the parameters used for programming the STM32 (I'm assuming you are using stlink command line tools). 3. Have you tried replugging your Blue Pill after reprogramming? I haven't been able to get USB re-enumeration you work reliably on this platform. Thanks, Jean.

Is this "special" bugged bluepill? All hardware is OK (R10=1.5k), soldering is fine. i've tried with noloader parameter, 2k,4k. Same effect. Used to uploading ST-link v2. — Reply to this email directly, view it on GitHub, or unsubscribe. You are receiving this because you are subscribed to this thread.

Thanks, Jead.
I should say there is same problem with HID bootloader (https://github.com/Serasidis/STM32_HID_Bootloader).
Here is a log. Building from the source (last update on Dec 14, 2022):

Thanks for your report. It appears that you have an undocumented counterfeit STM32. I found a user on the net facing similar issues with their STM32 board: qmk/qmk_firmware#17605

Unfortunately I don't know where to investigate, and I can't justify spending a lot of time fixing buggy STM32 clones. If you ever find relevant resources about STM32 clones, or have a patch I could integrate, feel free to reach out.
