Hello
I use at91sam9260ek board and I try to load u-boot to it. I tried to write u-boot.bin file to the NAND Flash memory by atmel sam-ba software and USB. It seemed to be loaded successfully (that was log information), but unfortunatelly teminal still showed RomBoot. Moreover I cannot use sam-ba for the second time because my PC can't detect usb connected to the board. I decided to use JTAG and Jflash software to repet the operation. The arm9 core was detected and I was able to erase all nand memory. Unfortunately my uC still stops on the RomBoot and finally JTAG is no longer detected by my computer.
What does happen with it? How can I fix it when I cannot get into the NAND memory? I would be grateful for any ideas or help.
