which look like it is working
as a workaround I was able to get it to flash my device by setting the _flash_size to 384 if it was 0 after trying to get the size in find_mcus_by_flash_size()
so it seems it is having an issue detecting the flash size
Yes, this is bug, or nonstandard by ST, I see this, in datasheet in section 31.1.1 Flash size register is exception for devices with your dev_id 0x436
, where can be 0 for 384KB or 1 for 256KB of FLASH. other devices have on this address size of FLASH in KB
this need an workaround for this dev_id as dirty fixup, you can try to add this exception here: https://github.com/pavelrevak/pystlink/blob/master/pystlink.py#L121 I will make fixup later
Cheers mate, this project is awesome, I was seaching for a stlink programmer that would run on a 32bit raspberry pi for ages and nothing worked apart from this.

I get similar results with the stlink v3
