Killed my STR9 ?!

Hi

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 :(

Hi,

Try to use the CAPS tool in order to make an erase operation at least you can erase the Flash.

pls find related documents through this link:

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.

Hi,

CAPS tool supports now the Rlink jtag tool, you can us it instead of Flash link.

Best regards,

I checked CAPS, but I for one have no parallel port anymore on my work-box and for the

other machine I have it runs Linux.

Anyway thanks for the hint.
