Will continue to test. I was originally only planning on using this as an LMS / file server but it would be a nice bonus to have working audio out too. I've learned a lot working on this. One thing that initially almost made me give up was issues I had with Alpine's apk package manager. It took me a while to get to the point where I had a bootable base system and then the one application that I wanted to work correctly, the package manager, didn't. If you are interested, you can read about it here: https://lists.alpinelinux.org/~alpine/apk-tools Subject is "APK Package Name Issue on armel port". The developers were great and commited some patches to fix the problem (fixes included in the tar ball you got.) It was down to unaligned memory access, which after I knew what I was looking for I was able to read up about but I wouldn't have figured it out without the Alpine dev diagnosing it. I haven't quite figure out why yet, but, Alpine on the pi zero w defaults /proc/cpu/alignment to 2 (fixup) and I don't even think unaligned access is an issue on that architecture (not sure) but on the armel port I'm working on it was defaulting to 0 (ignore) which basically caused all the weird stuff with the package manager. I'm setting alignment=2 now as a kernel boot param, even though they fixed it in apk's code, just in case there are other apps that might cause problems. I tried to convince the guys over at the doozan forum where they were working on this device (I used the .dts and kernel config there as a starting point) that it was a potential problem on their Debian loads but I don't think I was able to get my point across. Not even 100% sure I'm right but I think I am. See starting here and on: https://forum.doozan.com/read.php?2,61344,96059#msg-96059 Anyway, just food for thought and if you have any opinions on anything I'd like to hear them! ------------------------------------------------------------------------ sodface's Profile: http://forums.slimdevices.com/member.php?userid=19057 View this thread: http://forums.slimdevices.com/showthread.php?t=111730 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
