Flash CC9U (UNC90) with JLink

[madmax80]

Hi everybody,
I have erased bootloader module CC9U (UNC90) and I want to flash it again. I connect with JLINK V8 the target through JTAG without problems. But no access to flash bank, I can’t. The process ends with error “could not find CFI compliant flash device” and the list of available flashes don’t appear. Nobody can help me for this? Thanks.

Sorry but I only opened this thread as I did not want to dirty the other post dedicated only to doubts about the jlink. By usb it is impossible for me to do it so I am trying for jtag although the program does not give me access to the flash memory. Thank you

It felt as if you did not accidentally delete the bootloader module CC9U (UNC90), I think, you had burned the processor.

Thanks for the answer, but I don't understand you. I have communication with the processor ok. Now the problem is that when it comes to programming it it returns me the failure of “ verification of RAMCODE failed address 0x00000000”. Thanks

comlekciler is saying the at91rm9200 is damaged, if not
look the at91rm9200 data sheet. (section Boot program).
follow the loading of the loading for a boot loader.

Yes, because when I received such an error related to the processor (verification of RAMCODE failed address 0x00000000) it was often damaged even if communication with the processor was achieved. So I couldn't use the processor again.
