Bug Report

Describe the bug

When attempting to flash Super Bluepill stm32f10x with the STlink V2, flash is unsuccessful due to STlink used having a different ID.

Warn : UNEXPECTED idcode: 0x2ba01477
Error: expected 1 of 1: 0x1ba01477

To Reproduce

SJSU-Dev2/demos/stm32f10x/super_bluepill_led_blinker was the project used for this flash.

Expected behavior

This is not a bug, The STM32 you have is a clone

VictorQueiroz commented 3 months ago

@danyhm Does that mean it's worse than the original? Is the "clone" problem an MCU problem or a board problem?

danyhm commented 3 months ago

@VictorQueiroz It's a MCU problem. The wafer silicon is different from the one STM designed. It's a clone where some features seem to be different or not present at all.

I tested an identical HEX file on 2 different Bluepill boards, one with original STM and one with clone MCU. The clone hanged at intervals cause of stack overflows

This is good info to know. Thank you @danyhm :)

This discussion looks resolved, I'll resolve this comment.
