Stumbled upon a bit of a mess... one of the batches of blue pill boards I got in had non ST MCUs on them (I think CS32F103C8T6?) which would not work with an ST-link, ho here is a warning and a workaround.

I never thought tech hacking videos could be so entertaining. I really like the style. Thank you!

Great update 👍😀

I was able to program and debug my board once with STM32CubeIDE. Then the SW complained of ST-Link firmware and wanted to upgrade. So I did and that killed the board. Now OpenOCD says: "Info : device id = 0x00000000, Warn : Cannot identify target as a STM32 family." Can I force the programming somehow? Just f***ing skip the whole device id check?

I bought an STM32 like in the video, I can program it in the Arduino IDE but the ST-link isn't recognized by the STM32 Programmer and the ports don't work.

OK I am posting a new comment about mine. It seemed with my blue pill you had to release the reset at the same time the cube programmer was waiting after pressing connect. About half the time it would connect and then program. At this point I installed st32duino which is happly ever after. Mine seemed to have this critical ttl programming timing.

LOL, with the chip shortage the fakes are selling for $7 shipped, not falling for that!

Simple way to check original or fake : debug it by keilc or stm32cube

I have one of this fake blue pills and there were no problems when programming with ST-LINK v2 (upgraded firmware). I am using Keil v5. Debugging also works. :)

A few of my troubles with Chinese "blue pill" clones. The CS32 work actually reliably once flashed, unlike many others that have grounding issues, some weird capacitance issues (wouldn't boot unless touched the right way), I had to throw away most of them as no amount of alcohol baths helped, but then found a good supplier on aliexpress selling those CS32 and every board worked perfectly. To flash them, you need to revert commit 3295ab4e5 in the texane/stlink repo (and fix the git conflict), optionally disable gtk3 GUI in CMakeLists, build it and then it works fine. And mine have 128K (Marlin wouldn't fit otherwise).

Do you know where to get REAL stm32 bluepills? Thanks!

Sometimes I fantasize about the damage done, world wide, by use of these "write only" fonts. Like URLs in the address bar, passwords written down incorrectly, etc etc. Like a more insidious version of how doctor's poorly handwritten prescriptions kill patients.
