There is a way to make it really free software, but "Mychaela Falconia" systematically refuses to do it citing very unconvincing excuses.
OsmocomBB is free software, but it's not practical at all to use at all: -> Either you have a feature phone and you need to connect it to a computer running GNU/Linux, which runs part of the GSM stack. -> Or you have an Openmoko phone, and you cannot put the main CPU into suspend, because part of the GSM stack runs on it. So you get a very poor battery life. So some years ago, me and Alan Carvalho de Assis worked on fixing that, by adding the support for some osmocomBB supported phones into Nuttx. Once that would have been completed, we'd have to start porting the osmocomBB layer1 on Nuttx, then the layer 2 and 3. I did a quick and dirty port of the layer1, but it's too dirty. It also blocked when scanning the networks. OsmocomBB had a similar issue when using the same toolchain that I used. The issue is now fixed in osmocomBB. I think this should rather be done properly, even if it takes more time. Once the 3 layers would have been ported on the phones, we would only need to write an user interface for feature phones(or a protocol handler for the Openmoko phones). OsmocomBB supports several phones. On some flashing the bootloader is more risky than on other. Some also are not fully supported by osmocomBB, support for stuff like the flash or the battery charging is sometime lacking. This is a minor issue given the use case of osmocomBB as-is. Denis.
