how to modify the u-boot configuration in SDK1.8?

[luwang]

I want to modifiy the u-boot configuration, the doc said that:

To Modify U-Boot Configuration:

Modify UBOOT_MACHINES. Values for UBOOT_MACHINES are listed in meta-fsl-ppc/conf/machine/<machine>.conf

My UBOOT_CONFIG is:

UBOOT_CONFIG[sdcard] = "ls1021atwr_sdcard_config,sdcard"

but I can not find the "ls1021atwr_sdcard_config"  to modify the configuration.

I try to use make menuconfig, then use bitbake to compile, but it does not work too.

so how can i modify the u-boot configuration in SDK 1.8??

thanks a lot

Hello Lu Wang,

Please configure the variable UBOOT_CONFIG as "sdcard" in the recipe meta-fsl-arm/conf/machine/ls1021atwr.conf.

And rebuild u-boot as the following.

$ bitbake u-boot -c cleansstate

$ bitbake u-boot

Have a great day,
Yiping
