I have bought E3 recently in hope I could use it as IP phone, or even POTS phone with extra newtworking features. I alread have asterisk running on it, controled from keypad via lirc, with led provided visual feedback. Two parts are missing: working sound driver for handset/speakerphone and input driver for hook switch. It looks like most develompents have ceased about 2 years ago, but I have some questions if you are still there.
I've actually compiled up a kernel more recently than that to check it still built ok, but haven't done anything much with the E3 recently.
Questions to Jonathan McDowell, maybe others: 1. Did you succeed in talking to the handset over the modem chip in full duplex?
No. I did wonder if boosting the speed to 230.4k rather than just 115.2k might help.
2. Did you try to create a driver for hook switch hanging off GPIO input 4, as Matt Callow detected it once? If not, what hints could you give me for creating one?
I had this hooked up to the OMAP gpio switch framework, but I found it conflicted with the FIQ keyboard patch and caused crashes. Possibly the gpio-keys driver is the way to do this these days?
3. As googling did not give me any answer, where can I find any info on Q;Q; block format?
If you limit Google to the list archives you should have more luck.
More questions: 1. Has anyone managed to boot a kernel built from Amstrad provided sources (linux-2.4.18-mv30-E3.tar.bz2)?
I haven't.
2. What is the format of a copy of the kernel taken from the device (kernel2.4.18_mvl30-ams-delta)? Has anyone managed to boot it with u-boot or other open source loader?
I didn't really investigate it. 2.4 doesn't interest me.
3. Has anyone managed to make any use of flash image backups, for example, for examining filesystem contents?
Yes, you can dump the contents but I don't recall anything of real interest there. J. -- Do you believe in happy endings? This .sig brought to you by the letter S and the number 3 Product of the Republic of HuggieTag
