Custom Firmware image creation

[Ghouse]

Hi, iam using LS1046ardb in a custom card, i want to change the rcw file and build the firmware image with the modified rcw file.

please provide the complete process for generating custom firmware image using modified .rcw file.

Although flex-builder -c rcw -m ls1046ardb can be used to make the "bl2_qspi.pbl",  i want to know if there a procedure to generate the firmware image using .rcw or bl2_qspi.pbl..

Please refer to file configs/board/ls1046ardb/manifest, rcw_1800_qspiboot.bin is used to generate atf/firmware image.

rcw_qspi="firmware/rcw/ls1046ardb/RR_FFSSPPPH_1133_5559/rcw_1800_qspiboot.bin"

1. Please execute the following command.

$ flex-builder -c rcw -m ls1046ardb

2. Please modify RCW file components/firmware/rcw/ls1046ardb/RR_FFSSPPPH_1133_5559/rcw_1800_qspiboot.rcw for your custom board.

3. Rebuild rcw and atf.

$ flex-builder -c rcw -m ls1046ardb

$ flex-builder -c atf -m ls1046ardb -b qspi

4. $ flex-builder -i mkfw -m ls1046ardb -b qspi
