Title: Flash CC9U (UNC90) with JLink Post by: madmax80 on May 17, 2020, 05:47:55 17:47 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.

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 Title: Re: Flash CC9U (UNC90) with JLink Post by: pickit2 on May 19, 2020, 12:25:04 00:25 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.Title: Re: Flash CC9U (UNC90) with JLink Post by: madmax80 on May 19, 2020, 11:09:53 11:09 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.
