i'm using arm cortex m4 "STM32F407VGA" that was working properly but it stopped working now the driver is OK the debuggers settings are also right what can i do??? or if it is possible how can i do factory reset ??
Ok, so see the BOOT0 and VDD pins half way up the connector on the right side, jumper them together.
Alternatively go into you debugger settings, and select "Connect Under Reset", and then go erase the part. Got ST-LINK Utilities? Use those.
Thanks a lot for the information.
Connect Under reset worked for me!!
