Is it possible to create firmware for button mobile phone?

[evetrov]

Hello guys!
I’m middle fullstack web developer, but new to this RTOS and C/C++ developement.
I want to create good firmware and soft for simple button phones like this:



I looking for any info about creating firmware for button phones and people, who did it. Try to find firmware with open source code, try to find documentation, but no result. I found only Simbian OS from Nokia on github, but dont now how to compile and launch it.

Some days ago i found info about platform for creating button phones firmware: Nucleus RTOS and RTOS as a whole. Nucleus is used in most phones now.

Is it real to use ChibiOS as base for creating firmware for button phones?
What you know and can advice me about creating firmware?
Is there starter kit or template firmware for phones (with GSM drivers, working SMS, GPRS and other mobile communications)?

Hi,

Yes, it could be used in a phone like this.

What you know and can advice me about creating firmware?

You may try http://www.playembedded.org this forum is not about teaching/training.

Is there starter kit or template firmware for phones (with GSM drivers, working SMS, GPRS and other mobile communications)?

No, as far I know. Drivers and such should be supplied by the chipset vendor.
