uboot % jethome-boot-fip

Firmware Image Pacakge (FIP) sources used to sign Amlogic u-boot binaries in JetHome images

U-Boot/BL33 Firmware Packaging

Usage: ./build-fip.sh: <board model> <bl33/u-boot.bin path> [output directory] [temporary directory]

Pass the board name and the bl33/U-boot payload to generate a bootable binary.

Example:

$ mkdir output
$ ./build-fip.sh jethub-j100 bl33.bin output
make: Entering directory 'jethub-j100'
python3 acs_tool.py bl2.bin /tmp/tmp.l9HlAIaFaN/bl2_acs.bin acs.bin 0
ACS tool process done.
