The shielding covers of this model are soldered, not snap-on :(

Specification * GSM 900 / GSM 1800 dual-band * 101 x 47,8 x 21,9 mm, 80 grams * 920mAh Li-Ion battery * TI Calypso/Iota/Rita chipset Schematics

The schematics can be found e.g. at http://files.shrak-mobile.com/schem/motorola/C139_schem.rar. They apply to C139 as well as C140, as they are very similar.

Miscellaneous

=== 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 * To bypass this limitation, use the Calypso romloader to chainload the application. Here's an example for loading layer1.bin:

{{{
$ ./osmocon -p /dev/ttyUSB0 -m c140 -c ../../target/firmware/board/compal_e99/layer1.highram.bin ../../target/firmware/board/compal_e99/chainload.compalram.bin
}}}
