Hi, I have two boards ( the same ), using stm32L151C6 micro vision 4.53 and ULINK2 I succeded to programm the first one severals times (about 10), till it stopped programming and give me these two errors: 1) cannot enter debug mode. 2) cannot access memory.
nothing was changed in the configurations of micro vision!
In the second board, I also succeeded to program it severals time, till it stopped working giving me the error: SWD communication failure.
