  1. Ok, the old one has been delete, everything works fine: root@nanopineo:/# cd boot root@nanopineo:/boot# ls armbianEnv.txt dtb-4.19.38-sunxi armbianEnv.txte initrd.img-4.19.38-sunxi armbian_first_run.txt.template overlay-user bin script.bin bin.old boot.bmp boot.cmd uInitrd boot-desktop.png uInitrd-4.19.38-sunxi boot.scr vmlinuz-3.4.113-sun8i config-3.4.113-sun8i
  2. Hi, can you please describe the process for removing the old one? Also, how can I update armbian-config's database to reflect a newer choice of Kernels in the 'switch kernel' section? Thanks
  3. I'm not sure what happened, but after running an apt-get upgrade recently, it bricked again. Here is a serial dump: U-Boot 2018.05-armbian (Sep 19 2018 - 12:21:54 +0200) Allwinner Technology CPU: Allwinner H3 (SUN8I 1680) Model: FriendlyARM NanoPi NEO DRAM: 512 MiB MMC: SUNXI SD/MMC: 0, SUNXI SD/MMC: 1 Loading Environment from EXT4... ** File not found /boot/boot.env ** ** Unable to read "/boot/boot.env" from mmc0:1 ** Failed (-5) In: serial Out: serial Err: serial Net: phy interface0 eth0: ethernet@1c30000 230454 bytes read in 45 ms (4.9 MiB/s) Unknown command 'bm
  4. Thank you, that fixed it. You need to boot into Linux on a computer with the SD card inserted into the computer you're booting from. The best way to do this is to download a distro that you can burn to a DVD. You then boot from the DVD when you restart your computer. I used kubuntu-19.04-desktop-amd64.iso. Next, after you boot from the DVD, make sure your internet works (you will have to connect your WiFi in the Kubuntu desktop) and then you need to download the Armbian package that contains the DTB that corresponds to the kernel you updated to. In my case it was Kernel 4.19.38. O
  5. So I did the following today: Everything went fine except at the end where it complained about busybox not being there and it failed the update of initramfs... This was no issue. I installed busybox, rebooted, ran apt-get autoremove and then autoclean and everything worked fine. I was still on kernel 3.x, so I ran armbian-config but I did not see the latest kernel present in the switch kernel option. I ran apt-get install (or something similar) and it installed, so I then rebooted. Now it's bricked. I'm attaching the serial console output. Please help
  6. Can someone please tell me if I need a latency patch? Here are my results: root@nanopineo:/home/nanopi/rt-tests# sudo ./cyclictest -a -t -n -p80 # /dev/cpu_dma_latency set to 0us policy: fifo: loadavg: 0.73 0.63 0.42 1/98 8763 T: 0 ( 8735) P:80 I:1000 C: 101511 Min: 10 Act: 61 Avg: 65 Max: 2279 T: 1 ( 8736) P:80 I:1500 C: 67687 Min: 11 Act: 50 Avg: 62 Max: 252 T: 2 ( 8737) P:80 I:2000 C: 50765 Min: 11 Act: 49 Avg: 59 Max: 248 T: 3 ( 8738) P:80 I:2500 C: 40612 Min: 12 Act: 62 Avg: 61 Max: 312 and here's my current kern
  7. Sounds good. I locked myself out of Webmin last night and the SSH isn't accepting the default password, so I'll have to access it via serial console (It's not made perfectly clear in the documentation, but you need a serial to TTY converter for this to work). I already used the console for the initial install so I know that it works perfectly (Use something like ExtraPutty in UTF-8 mode to get a nice colorful console). My next step will be to apply the latency kernel patches... Thanks for mentioning armbian-config. I'll definitely have to install that, as
  8. I recently received my kit, which consists of the Neo, heatsink, and acrylic shell. Installed Debian_jessie_default.7z with Etcher onto a Kingston SDCIT/8GBSP. PCB 1.3+ uses a more sophisticated voltage regulator than earlier revisions... The temperature is excellent so far (only 40c). I can run some more tests if someone provides instructions. So these boards do not in fact require a heavy copper plane for heat dissipation. I did use a superior heat pad rather than the one that is provided with the heatsink kit. Ideally, you would want some
