Used tools:
- stm32cubeprogrammer
- STLink-v2 (wired pins: 7:swdio, 9: swclk, 1: vcc, 8: gnd), the dev board usb is plugged to supply the chip.
- tried with all reset combinations, bus clock configs and boot0 config.
- tried with openocd as well (see console log below)
- tried with one of my own board (stm32f4x) to check if my tools are still working properly, I can read memory of the chip perfectly.
Questions:
- Do I miss something to make chip debug probe connection working ? I generally never had trouble to connect it to my boards. Anyway this is the first time I work on STM32f0 series.
- I heard possible fake MCU's sold on some websites (I used banggood, the price were quite low), do you thing it could be the case ?
