Hi everyone, it’s me again… after a lot of digging I found the issue…
First my OPENOCD_SCRIPTS was pointing to an OpenOCD modified for ESP32, so the [find xxx] command was just not doing well
After, I had to set the variable STLINK_VERSION to 2 with this command line
make STLINK_VERSION=2 QUIET=0 BOARD=bluepill-128kib flash
And as Marian said… manual reset as STLink v2 clone doesn’t do the reset even though the RESET pin is connected.
Even though I’ ve connected a USB_UART converter to PIN A9 and A10 as it says periph_conf.h I have no stdout output… do I need to enable anything else?
