i.MX25 3 stack board - boot error

[arumugamramasam]

Hi,

I am using i.MX25 PDK 3 stack board. I tried erasing the nand flash using ATK tool 1.71 through com port and downloaded the uboot, uImage and rootfs.jffs2 given with the kit L2.6.31_09.12.00_SDK_images_MX25 as mentioned in the user guide. After downloading these into flash successfully, I tried booting but I am facing error as attached when the sequence comes to loading kernel stage. Kindly help me to resolve this issue.

Thanks,

Hi,

first of all forget samsung, they change flash model once a week.... Micorn is ok they have a long life program.

I have to check how to add a new model of flash. Also uboot have to be modify to supprto new model (if not yet included in the description file).

Anyway you need the ATK source, and somewhere there is a file with a c_table describing the model supported (mainly the manufacturer ID , model Id and geometry info...)

i think it is trying to boot from a remote tftp server but the server ip is not set.

you have to change the boot argument in the uboot : check the enviroment

I don't remember in that version, but stop the autoboot pressing a key

at promt digit printenv you will see an env variable bootcmd = run bootcmd_net (or similar)

you have to change it to run bootcmd_nand (or similar)

Thanks Omar… It was useful, I am able to boot it from flash without configuring ip and all.

I have another question and I would be happy if you can support me for that too.

Actually I have replaced the Nand flash from the default (Samsung part) to an equivalent Micron part and I would like to load the uboot, image and filesystem on the new flash using ATK tool. Is it possible to load directly or any other preparation work I have to do.

I am not able find any information in the user guide regarding this change of flash and its significance. Kindly help me to get the necessary information to proceed with the new flash.

Thanks in advance…
