Write new rcw binary on the sd card image

SoccerMom — Wed, 04 Jan 2023 17:26:40 GMT

Hello,

I have an LS1028ardb board with LSDK21.08. I boot it from the SD card using firmware_ls1028ardb_sdboot.img. I have modified the RCW for that LSDK and converted it to binary format. How can I write over this new rcw binary on the firmware_ls1028ardb_sdboot.img?

Thanks

I also tried to boot lsdk21.08 from NOR flash and then imported the original_rcw.bin in the PBL tool and just changed a field for GPIO and tried to write over the modified_rcw.bin in the NOR and boot up again. It does not not work, it does not transmit anything on the serial port.

originial_rcw.bin

modified_rcw.bin

Thanks

Confirm the */flexbuild_lsdk2108/configs/board/ls1028ardb/manifest select rcw_sd,

rcw_sd="path/*.bin"(make sure the path is the required bin file)

$ cd flexbuild_lsdk2108/

$ source setup.env

$ flex-builder -i clean-firmware

$ flex-builder -c atf -m ls1028ardb -b sd

$ flex-builder -i mkfw -m ls1028ardb -b sd

Now the required image is available in*/flexbuild_lsdk2108/build/images
