Recompile Uboot did not take effect ls1021a

jiye — Thu, 13 Feb 2020 19:00:23 GMT

I am using

flexbuild_lsdk1906/packages/firmware/u-boot/configs/ls1021atwr_sdcard_ifc_defconfig

I changed the settings in the deconfig file and then use

flex-builder -c uboot -m ls1021atwr -b sd

the new uboot bin file then generate under

flexbuild_lsdk1906/build/firmware/u-boot/ls1021atwr/uboot_ls1021atwr_sdcard_ifc.bin

Then I dd this file into my SD card, I tried to verify from the uboot prompt window for example I set the bootdelay to 5,

and when I checked from the uboot prompt window it still shows me default bootdelay=3

Can anyone help me with this?

Please remove the build folder, then build u-boot from the scratch.

1. rm -rf build/firmware/u-boot/ls1021atwr/output/ls1021atwr_sdcard_ifc_defconfig/

2. Please modify packages/firmware/u-boot/configs/ls1021atwr_sdcard_ifc_defconfig according to your requirement.

3. flex-builder -c uboot -m ls1021atwr -b sd

4. Get the latest image in build/firmware/u-boot/ls1021atwr/uboot_ls1021atwr_sdcard_ifc.bin

Thanks,

Yiping
