  1. Hey suber. I just installed LXDE 10 on mine and it's a big issues really surprised at how it runs cool and smooth. Uses about half of my 1 GB ram and some swap space with Ffox hexchat lxterm open. I'll try KDE Plasma soon. Thing about rock64 boards is there's 3 versions and I had to try a few distros until I came back to ayufan after he finally caught up on his images. He must know this board well I assume. Board sat for a month here. I was too frustrated with it. So try arch manjaro armbian too. IMO the various devs focus on different uboot / kernel / userspace versions and that introduces issues. It's an arm thing due to building for chip families vs individual boards/versions. Try not to give up too fast on it. It's not a great or popular board for obvious reasons (cheap) but once it works it's a relief. I would use an sdcard first then if thats ok, an emmc.
  2. Update: kernel 5.6.0 boots on my V2. I just installed latest ayufan ubu focal unstable image and its been ok for a day now. Time will tell if this becomes my main image vs arch/manjaro/armbian. I'll try armbian again when a stable release is out with this kernel.
  3. I'm using a sandisk Ultra 16GB sd card. Never used emmc yet. Originally flashed and used spi usb boot w/o any probs. I flashed it back to empty in the testing im doing last 4-5 days. I'll leave spi alone and empty for now. Martin: I tried a jumper on emmc pins by the lights. Didn't help. May be that my timing isnt right ...boot with jumper stop the boot with a keystroke, remove jumper, hit a key and continue booting. Since lanefu's new v2 booted and tonys then the sdcards are more robust than this sandisk ultra? It's a brand name top card so that baffles me but could be the problem. Thats surely not the solution though. What kernel? the kernel in the current image dated 1-26-2020 plus I tried a build from lanefu that has 5.4.20 with latest patches. I read in a thread that the boot order is spi>emmc>sd. It used to be spi>sd>emmc and that change has caused lots of probs for pine products. Sounds to me like its about that order and the voltages being used and how that ruins the sdcard's chance of booting due to corruption. Plus using really old configs from ayufan from 2 yrs ago (no matter how updated) when the board was released is imo not right. I've enjoyed the hunt for this problem but i'm getting tired since the fix isnt some simple file edit or switch to a different image a plain user can do. I've done and reported what I resonably can.

  5. Applying kernel provided DT fixup script (rockchip-fixup.scr): Finally got a serial board so theres the output. Hope this helps to fix my V2 rock64 on new images. This is for latest standard buster server RC image. Not syncing is usually it cant find the right partition to complete the boot.
  6. I'm new to armbian so hi to all. I recently bought a sealed Rock64 v2 off ebay with psu and sdcard for low cost. It works ok but has lots of same issues like others have. I'm just adding my 2 cents in here so another user is heard in the thread. Armbian Bionic w/4.4 minimal works well. Anything else newer does not boot. I dont have serial cable so that's all I can report for now. Compiles well too. Arch and Manjaro stock images work well (5.5.1) but they segfault when compiling anything. Still looking for an image for v2 that compiles and is 5.2 or newer.
