Hi
I am using LPC3250 based on phyte3250.
I am using Linux BSP provided by NXP.
I want to do firmware upgrade -mainly rootfs through SD card.
I want to do it directly from uboot So that it can recovers if it fails during update also.
In Uboot SD card is disabled by default.
I enabled the generic configuration to build it.
but I am not successful in using the API.

Please let me know if anyone here is using LPC3250 and can do root fs update through SD card.
I do not want to use console to do it.

If require I can pay for the feature also.

NO.
All these documents explain about booting from SD card.

I am looking help to update rootfs file by using SD card.

I do not want system to boot from SD card.
Just copy the rootfs to RAM and Write to nand.

What I am missing to activate the SD card in Uboot and copy file to ram.
The way we do load in S1loader.

Write to Nand I can use same which I use currently for tftpboot.

Please let me know if you have any question on this.
