Hi Sir :

Use eMMC to boot uboot.

I can't find where to write uenv.txt.

--------- u-boot command line ---------

fatload mmc 1 ${loadaddr} uenv.txt
mmc write ${loadaddr} 0x???? 0x????

Hi Pierre,

uenv.txt is used for MMC-SD.

You can simply enable saving env in eMMC.refering the above thread.

Let me know if you are able to saveenv in eMMC.

Once you saveenv the next boot need not have any bootargs keyed in.

Best Regards,
Keerthy
