=== Bootloader ===

The loader is pretty much identical to the loader in the C123.  However, it has one additional nastiness:

 * After the download has completed, it expects the magic string "1003" (0x31 0x30 0x30 0x33) at the RAM address 0x803ce0

 * Use the osmoload model-switch "-m c140/c140xor" and upload the [wiki:Bootloader], and use osmoload to load the application (e.g layer1.osmoload.bin)
