| 51 | === Bootloader === |
||
| 52 | |||
| 53 | The loader is pretty much identical to the loader in the C123. However, it has one additional nastiness: |
||
| 54 | * After the download has completed, it expects the magic string "1003" (0x31 0x30 0x30 0x33) at the RAM address 0x803ce0 |
||
| 55 | 9 | laforge | * To bypass this limitation, use the Calypso romloader to chainload the application. Here's an example for loading [wiki:layer1.bin]: |
