Hi,

I use embedded yocto to build a real time linux environment on a board. The kernel rootfs and bootloader are stored on nand flash, on a different partition each.

When I type in the bootloader

mtdparts

I observe the following:

=> mtdparts

device nand0 <gpmi-nand>, # parts = 7 #: name size offset mask_flags 0: bootloader 0x00300000 0x00000000 0 1: environment 0x00100000 0x00300000 0 2: safe 0x00100000 0x00400000 0 3: linux 0x00e00000 0x00500000 0 4: recovery 0x00e00000 0x01300000 0 5: rootfs 0x08000000 0x02100000 0 6: update 0x05f00000 0x0a100000 0

active partition: nand0,0 - (bootloader) 0x00300000 @ 0x00000000

defaults: mtdids : nand0=gpmi-nand mtdparts: mtdparts=gpmi-nand:3m(bootloader),1m(environment),1m(safe),14m(linux),14m(recovery),128m(rootfs),-(update)

I can modify this by typing

setenv mtdparts 'mtdparts=gpmi-nand:3m(bootloader),1m(environment),1m(safe),14m(linux),14m(recovery),112m(rootfs),-(update)'

How can I modify this by modifying the uboot code?

Thanks
