Hi,
If I remember correctly, i got the same issue on AT91SAM9263ek.
you please debug the Dataflash_Select() ... there u many need to go into the if condition and do valid=1;
so, please check it once and modify the condition...
u may get the solution ..
Thanks, Seetharam

Hello, this is my first post in this Forum and my English is not very good so I give my best to describe my problem.
I have a AT91SAM9260 eval kit board and until now there were not very much problem. But what stops me now is a really tough problem. I use the Bootstraploader for NAND boot which is compiled by Atmel in the Demo. I've compiled the U-Boot by my self and its starts without problem, but what get on my nerves is that I can't write the U-Boot env over .tcl file. To explain that, I load everything, just like it is done in the demo, with this batch- and .tcl-file. So, I've checked the checksum for the env's but everytime I uploaded it and trying to boot I get this:
U-Boot 1.1.5 (Nov 2 2006 - 10:20:33)

I checked the env (nand read to copy them in the RAM and md to hae a look at them) and they're still correct. Well, I could write the env every by hand that would work but if you have to do this 20 times a day and you have really much to write this wouldn't be very funny.
So I hope I haven't forget anything, but if there is any question I will try to answer.
