You can find me in #linux-amlogic on Libera.Chat.

Usage

$ acsbaby [-t acs|bl2|u-boot] [-o offset] file

Options

-t type

• Forces/Sets the image type. Can be either acs, bl2, u-boot, or u-boot-512. When unset ACSBaby will try to detect which type to use.

-o offset

• Sets the offset where the ACS footer is to be found. Mainly useful when dealing with signed U-Boot binaries. A small script is provided too for finding the offset to use.

Examples

Parse an ACS binary:

$ acsbaby -o 0x0000a4e0 u-boot.bin

Compile

Modify Makefile to fit your needs, then run:

$ make

TODO

• Support other ACS versions

Known issues

• Endianness: Little endian byte order is assumed in the code, thus running on big endian hosts may cause unpredictable misbehaviour.
