Hi all

I am facing a problem with my AT91SAM9260 customized board. Board is almost same as the evaluation kit.

I could download the binaries ( Bootstrap-v1.16, u-boot-1.3.4, linux kernel 2.6.20) successfully to the DATAFLASH/NANDFlash in my board by using atmel SAM-BA tool with usb/serialport/jlink.

Here I describe the problem.

When I power up the board, boot strap is not jumping to U-boot location, in the normal boot sequence and board stuck with bootstrap.

But when I disconnect/connect the JTAG USB cable ( provided with SAM-BA ICE) , it's jumping to u-boot location and booting the board properly. I'm getting the same error in NAND FLASH also.

I have tried one more test case.I copied bootstrap binary at the flash location, [location which is specified for u-boot binary] instead of U-boot.bin (location: 0x8400 in dataflash), I got continous bootstrap debug messages in my console. [ So can I conclude SDRAM doesn't have any problem? ]

Where should be the problem.? Bootstrap code or U-boot code ?
Please guide me regarding this.


Thanks & Regards
