Hi Wang,

If you modify the u-boot you need to download the new one to your board. You can use the mfgtool to download. If you are using the newest BSP you need to use the tool UUU.

Hope this can do help for you

Have a nice day

Best Regards

Rita

Hi Rita,

 Because my board nand flash size is only 256M,but the image build from Yocto project is larger than it,So I only use sdcard to debug now. Can update u-boot on SDCard?

Best Regards
