Can't debug

Posted by deksnys4life on 2019-12-12 08:16

Hello

I’ve been using my STM32L053 DISCOVERY board for a few months. It worked until yesterday. I wrote a program to write a 4 char array to eeprom, under my lecturers supervision, and suddenly my and four of my student mates boards “crashed“ during debugging session.

Those are the errors that we are getting:
E310  : Debug access failed - cannot read address 0xF0000FE4 (accsize ‘4’, AP ‘0’)
Error: Flash download failed - Target DLL has been cancelled

We tried reinstalling the drivers and restarting our computers. We also tried reflashing firmware with STM32CubePrg, changed debug connecting settings in project options - neither of the above works to solve our problem.

Anyone has any ideas how to solve this?
