  1. Hi All, this was caused by a hardware problem during the detection of the second USB-device. The system tried to create the node, but becaus of the hw failure it created a regular file. If someone tried to delete this file, the system recreated this wrong regular file again, what can be seen on the new I-Nodenumber. This situation persists even after a reboot without the failing USB-Stick! Here is my solution how I fixed this: I rebooted without any USB-device, and then reconnected each USB-2-Serial stick again each after the other. Regards wollik
  2. Hi Werner, I don't know what is missing so I put some additional informations. I'm using a A20 SBC so I put it here, please can you move it to the right forum section ? I don't think this is a bug, I just want help how I can get rid of this wrong device. Regards wollik
  3. Hi Linux Admins, I have a wrong device in the /dev direcrory and can't delete it. Here is what I get when I do a: ls -la /dev/ttyUSB* pi@armbian_test: ls -la /dev/ttyUSB* crw-rw---- 1 root dialout 188, 0 Feb 15 20:47 /dev/ttyUSB0 -rw-r--r-- 1 root root 1 Feb 15 20:48 /dev/ttyUSB1 You see that the device ttyUSB1 is not character device and has no major device number assigned. Also the device belongs not to the dialout group. The causing USB_2_Serial Stick is disconnected and the device entry is still there. Trying to remove
  4. Hi Brosinski, this image is still Armbian 5.31 sunix 4.9.7 and so you can’t use it with the newer armbian-config (Version 5.90) II‘m currently using the image found on the bananian forum 2020-04-21-armbian-buster-lite.k419img.zip That is still 5.31 but sunix 4.19.62) You need to modify the armbian-config environment to get the additional functions to run. On one of my r1 boards the WiFi worked directky, on an other I'still troubleshoot the WiFi connections. I have had a Armbian 5.9x running, but my SDCARD breaks, so I will try to build my own image with the latest armbian ver

  6. Hi Werner, I just want inform you that is just booting half way up , it gets an IP via DHCP and tries this over and over again, but the IP is o.k. and you can ping it. I understand that there will be no support. My plan is to understand the bootprocess to trouble shoot my broken sd card, the fsck looks good on my card, but it don't boots, no prompt at all on the monitor. Do you know if there are any messages or bootinformations avalable via what tty? Regards WolliK

  8. Hi Werner, I've had Armbian Buster running on this SBC but my SD-Card crashed, "no valid Superblock" I might have had running the Armbian_2020-05-2... that is also for the M1 with the Allwinner A20, but I don't remember what I have used in the past. I've already checked the internet, thanks for this hint but I thought that I can get a link via this forum members since I and hopevully also others are still using Armbian 20-xx on R1. Does anyone else knows which Armbian Buster Image runs on Lamobo R1 and where I can download it? Regards WolliK

  14. Hi xwiggen, T H A N K you, that solves my MAC address problems. Regards WolliK
  15. Hi All, I''m using a BPI M2 Zero, where a 100 MBit ethernet Interface is implemented on the board. Since I'm using DHCP for this interface, I found that the MAC Address of this eth0 interface changes on every boot. The MAC Address of the wlan0 interface is permanent and don't changes during boots. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Di 30.
