Hello U-booters
Hopefully someone can help me. I'm working on a tx25 target.
I need to start my linux system from nand flash. i can load the kernel-uImage from tftp and start it directly without any problem. I stored the image to the a mtd partition.
nand write.jffs2 0x81000000 kernel1
To continue I need to power off the System for a while. The first or the first few loadings of the kernel works but afterwards it is not any more possible to load the kernel correctly. the following commands have been done in one succession
=> nand read 0x81000000 kernel1
NAND read: device 0 offset 0x80000, size 0x400000 4194304 bytes read: OK => iminfo

Does anybody have an idea where the problem comes from.
What version of uboot do you use ? btw try ubi/ubifs, might be better than jffs on big NAND devices.
Cheers
I use U-Boot 2011.03
I have no idea how to save the Image on a ubi, sorry I'm quiet new to U-Boot. I tried the following instructions without any success
nand write.ubi/ubifs nand write.ubi nand write.ubifs ubi help ubi
Where can I find the manual for nand and ubi? I didn't find it on the denx wiki.
