Hello,

I've managed to use st-link to install MicroPython on an STM32-H743ZI2 Nucleo-144 board weeks ago, using @Ant-ON's version.

Recently I wanted to dive deeper into STM32 programming, but the ST-LINK doesn't seem to work after flashing with MicroPython:

root@7597058af286:~# st-info --probe
Found 1 stlink programmers
 serial:     303032413030334633343338353130433334333133393339
 hla-serial: "\x30\x30\x32\x41\x30\x30\x33\x46\x33\x34\x33\x38\x35\x31\x30\x43\x33\x34\x33\x31\x33\x39\x33\x39"
 flash:      0 (pagesize: 0)
 sram:       0
 chipid:     0x0000
 descr:      unknown device

I've also tried it with the current develop branch yesterday, same result. It appears to me as if flashing MicroPython somehow killed the ST-LINK interface and I don't understand how. According to MicroPython people this isn't supposed to happen, so now I'm asking here as my next station: is this normal? Is this a bug? What do I need to do to investigate?

I have a container image built for working with stm32 stuff if anyone feels like reproducing.

Thanks & Cheers,
Florin.
