Problem in SAM-BA connection : No valid processor ID found

Thu Sep 16, 2010 10:42 am

Hi all

I am trying to write into the dataflash of AT91SAM9260ek board. I have tried AT91-ISP v1.4 [which i got from ek CD] for connecting this board to host machine.

I selected the following options in ISP.

Code: Select all

Select connection : COM1 [only one option appears here instead of usb option.] 
Select your board: AT91SAm9260ek 
Its throwing me an error "No valid processor ID found"

Please help me out.

Thanks in advance

Hi

I could solve the issue.

Prior to connect SAM-BA, we must press BP4 switch while pressing reset button.

On AT91SAM9260-EK platform, there is no way to disconnect the on board DataFlash. If valid code is present in the first DataFlash page the chip will execute it before connecting to SAM-BA. (refer: linux4sam/bin/view/Linux4SAM/AT91SAM9260EKSamBaRecovery )

With out these, we were not able to select usb device or serial device to start SAM-BA. So got error: No valid processor ID"
