I already loaded some *.bin files, perfectly compiled with a perfectly functional tool chain.
But today it doesn't work anymore...
If I check with STLinkUpgrade 3.2.10, it tells me that the firmware is at version V2J30M21, which is also the last one.
When I try to flash the *.bin file with a simple drag & drop or copy-paste, the transfer seems to fail with the following error in the fail.txt file : The interface firmware FAILED to initialize the target MCU
What does it means ? how can I solve this ?
