How to update uboot into warp board

[TitusRathinaraj Stalin]

Hello Experts,

Can you please tell me that how can I update the new modified uboot into warp board ?

I think, we should copy the uboot binary into on board flash (first FAT partiton) and it should be possible to put the uboot binary into RAM using "fatload" command and we can update the uboot from uboot prompt itself.
Is that right or any other way is available ?
If yes, also I want to know which location we need to use to update the uboot ?

Thanks for your help.

Regards,

Can I use the following commands to update the uboot ?

#make boot partition writable

echo 0 > /sys/block/mmcblk0boot0/force_ro && sync

#clear uboot params

dd if=/dev/zero of=/dev/mmcblk1 bs=512 seek=1536 count=16

#write uboot

dd if=uboot.imx of=/dev/mmcblk1boot0 bs=512 seek=2 && sync

Hello All,

The above commands are can be used to update the uboot in Warp Linux.

PS : Those commands shoule be entered in warp board and not Ubuntu Linx PC.
