I cannot access my CPU with J-Link anymore after I did flash my own code into a str912-sk. Part of it write 0 into SCU->PRR0. J-Link stats it cannot stop the cpu. Is there a chance to do an ''full flash erase'' manualy ? Any help appreciate as I fear I otherwise killed the board :(
I had the same problem. The only way I could erase the chip was to use a different debugger (ULINK from Keil). After the chip was erased, I could go back to the J-link (IAR) and continue hacking.
If you have the SEGGAR J-LinkFlash license, you can use this with IAR J-link to erase the chip.
