  1. Thanks for the helpful hints. For now, I managed to create something hacky using the following approach: In debootstrap-ng.sh I commented out the line # rm -rf $SDCARD So now I had left valid rootfs and I could do armccrootpath=/home/vagrant/armbian/.tmp/rootfs-next-nanopineo2-bionic-no mount -t proc chproc $armccrootpath/proc mount -t sysfs chsys $armccrootpath/sys mount -t devtmpfs chdev $armccrootpath/dev || mount --bind /dev $armccrootpath/dev mount -t devpts chpts $armccrootpath/dev/pts cp /usr/bin/qemu-aarch64-static $armccrootpath/usr/bin/ chro
  2. I don't want to torture my SD card with full OS image rewrites or compilation on the device itself, so I would like to cross-compile. I just set up a ubuntu/bionic64 VirtualBox through Vagrant using https://github.com/armbian/build Currently, I don't want to build entire image or kernel from scratch but I noticed that compile.sh and related scripts contain many convenience functions and tools. I already started compile.sh once to let it prepare the virtual machine for cross-compile tasks and it successfully installed all the dependencies. I got especially in
  3. Thank you, after configuring it works fine and in stereo! So, I guess the audio codec drivers supplied by FriendlyElec were messed up. The sound quality is OK - good enough for listening on headphones or any non-hifi system. Will see how it works with ZynAddSubFx soon.
  4. Armbian_5.59_Nanopineo2_Ubuntu_bionic_next_4.14.65.img does not see the sound codec at all. The status matrix here: http://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix tells that Audio Codec should be supported since kernel 4.12 on H3 (H2+ is the same, as far as I know). But Armbian does not see the audio codec nor on NanoPi Neo2 (H5), nor even on on NanoPi Duo (H2+), although all the img files I used have 4.14 in their name. However, even with FriendlyElec's own image nanopi-neo2_ubuntu-oled_4.14.52_20180628.img there is a different issue - the sound is mon
  5. I live in a small Eastern European country and shipping from China still is almost always cheaper than from Germany or UK (and local stores are out of question when trying to find anything more exotic that RPi). I guess that's why FriendlyElec website also warns that EU orders are being shipped from China. Still curious about those AliExpress options, but I guess I'll better stay clear and order directly from FriendlyElec unless someone can confirm that there are trustworthy AliExpress stores that sell real NanoPis and not low quality clones (of course, SoC and layout being the sam
  6. Thanks a lot, I somehow missed NanoPi series entirely, shame on me. Those boards seem to be much better documented than Orange Pi products. I see NanoPis being sold also from Chinese companies RealQVol, Million Sunshine Technology and others, and not quite sure if they are just distributors or clones. I'm in Europe, so buying directly from FriendlyElec would ship from China, anyway; but other Aliexpress vendors offer better shipping rates (free), and also I can buy other interesting items from them, which are not available on FriendlyElec store. I just don't want to get caught by
  7. I've been considering some options for experiments with electronic wind instruments and synthesizers, such as ZynAddSubFx, Fluidsynth. I've seen project Zynthian and they are running it on a Raspberry Pi 3, so that should be a safe choice, right? Although I'm not sure if they are using some mainstream Debian or something heavily adjusted. Also, for a wind instrument I hoped to find something smaller so I can even build it into the instrument itself; although I don't have my hopes high on that - I'm not sure if I'll find an SBC with enough power. I happen to
