Hi I'm work on my custom board base on i.im28 evk.

 

The u-boot image (imx28_ivt_uboot.sb) was flashing with Mfgtool and I modified ucl.xml. My board does not have MMC.

So I'd like to change the u-boot environment variable to NAND without MMC.

 

The log is

MX28 U-Boot > saveenv

Saving Environment to MMC...

MMC0: No card detected!

MMC init failed

 

Can you tell me how to change it.

 

I got the u-boot source code this command.

./ltib -p u-boot -m prep

 

That source code is build.

ltib/rpm/BUILD/u-boot-2009.08

 

Thanks.
