Orkie still dives into GP2x development, which is a great thing. He recently contacted us to let us know about Open2x Bootloader. It’s an alternative bootloader for GP2X. Requires Orcus and DevkitARM to compile. ‘make’ will generate a gp2xboot.img file which can be flashed with the GPH u-boot. The bootloader has a simple command line interface accessible via UART – type ‘help’ to see the list of commands
The first release related to Open2x in 11 years (the Linux firmware hasn’t really changed).
