osmoload

NOTE: This is incomplete and experimental.

This command line tool is used to write, dump and examine flash memory of supported phones.

Currently, it can be used to dump memory and semiautomatically write it.

In order to use it you have to first put appropriate loader into baseband chip using osmocon.
In case of Calypso on OpenMoko it is loader.highram.bin

It can also do various things that are handy for firmware development, including
interactive memory examination and bootloader capabilities for various situations.
