46 | === Bootloader === |
||
47 | |||
48 | The loader is pretty much identical to the loader in the C123. However, it has one additional nastiness: |
||
49 | * After the download has completed, it expects the magic string "1003" (0x31 0x30 0x30 0x33) at the RAM address 0x803ce0 |
||
50 | 9 | laforge | * To bypass this limitation, use the Calypso romloader to chainload the application. Here's an example for loading [wiki:layer1.bin]: |
