  1. The command "nand-sata-install" has to be run from sdcard, but my Banana's system is running from an SSD. If repairing the HDMI port would mean to reinstall the whole system, I'd rather pass that one and live with a non functioning HDMI port. Is there any other way of getting the port to work again? What about special boot parameters?
  2. Hello! For some weeks now my BPM1 behaves a bit strange concerning video output. I used to connect my Banana to my monitor via a HDMI-DVI cable, which worked well for a very long time. Now, when I reboot the system, my monitor says "no signal", when I use that cable, as it does also when I use a pure HDMI-HDMI cable. The only way to make the Banana's video output work, is by using a HDMI-DSUB converter. But here comes the even stranger mystery: after I booted the Banana, using that converter, I can change the cable to whatever I want: HDMI-HDMI or HDMI-DVI, they both suddenly work again! But if I reboot the Banana again, not using the HDMI-DSUB converter, the screen stays black again. Like I said: that is not the way it used to be! I can not really recall when this strange behaviour started, but I assume that some kernel boot parameters have changed in one of the latest kernel versions. For now, the Banana is running Linux pi 5.4.88-sunxi #21.02.2 SMP Sun Feb 14 21:05:18 CET 2021 armv7l GNU/Linux and I have been using the 5.4 line for quite some time now, without any problems. If anyone have an explanation or even a solution for this strange video behaviour I'd be glad to hear it. I know I could simply go on using the HDMI-DSUB converter, but that input channel on my monitor is needed for another machine. So I am really looking for a way to make that HDMI-DVI cable work again.
  3. Hello, is there something like a VirtualBox that can emulate a BP(M1) hardware, that can run Armbian inside? I'm looking for a way to set up a new Armbian system for a BPM1, without having to shut down the running one longer than absolutely necessary. I have done this before with Linux servers: I installed and configured a hole server inside a VirtualBox alongside my normal computer work, then I copied the image to the real disk and swapped the disks, with a downtime of only about 5 minutes. So I was wondering if this was possible with the BananaPi as well.
  4. Well, that little difference between my PC and my BP is nothing I bother about. But I am still very curious about what cuts the download speed to half, when both machines download the same source. It feels as if the download server does not really want to give its data to the BP. ;)
  5. Here are my testing results. 1: "iperf -s" was run on the router: a) from PC to router: root@OpenWrt:~# iperf -B 1.1.1.1 -s ------------------------------------------------------------ Server listening on TCP port 5001 Binding to local address 1.1.1.1 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 1.1.1.1 port 5001 connected with 1.1.1.2 port 51174 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 1.00 GBytes 859 Mbits/sec b) from BP to router: root@OpenWrt:~# iperf -B 1.1.2.1 -s ------------------------------------------------------------ Server listening on TCP port 5001 Binding to local address 1.1.2.1 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 1.1.2.1 port 5001 connected with 1.1.2.2 port 43496 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 622 MBytes 522 Mbits/sec 2: "iperf -s" was run on the BP and on PC: a) from router to PC: root@pc:~# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 128 KByte (default) ------------------------------------------------------------ [ 4] local 1.1.1.2 port 5001 connected with 1.1.1.1 port 60463 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 1.07 GBytes 917 Mbits/sec b) from router to BP: root@bpm:~# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 1.1.2.2 port 5001 connected with 1.1.2.1 port 51657 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 725 MBytes 607 Mbits/sec The names have been changed to protect the innocent... ;) Unfortunately, iperf3 is not available for OpenWRT. But I hope the differences between the two version will not be too big to spoil the results.
  6. I know I can't compare the BP to my PC, and I don't want to. I am just wondering about this great difference when downloading the same file from the same server. As far as I know, downloading does not really require much CPU power, and if you redirect the data stream to /dev/null, it is also independent from any block device. I would understand it, if the difference was marginal or if the file came from two different servers or via two different routers or any thing like that. I agree to you, that most probably the reason for this difference in download speed has to be found outside the BP, and that's what I am trying to find out. But, like I told you, I switched the router, I switched the cables, but the difference always stays the same. And that has simply aroused my curiosity.
  7. That makes two of us. I was just trying to follow your advice: when I told of the slow download speed and the big difference compared to my PC, you ask me if I had updated the boot loader, and when that did not work, you ask me to run the SSD installation script. So, what are we talking about here?
  8. I am getting the same error saying "Test install failed. Can't change firmware" when I try to upgrade to kernel 5.3.9 and the file /tmp/switch_kernel.log contains just one line: linux-image-current-sunxi=19.11.3 linux-dtb-current-sunxi=19.11.3 linux-u-boot-bananapi-current
  9. I know what this message means. But the system has already been installed to SSD and is running from SSD right now. So, if I understand you correctly, in order to update the boot-loader, I'll have to shut down the system, remove the SSD, boot from SDCard, and then I am to call the command "nand-sata-install" without any SSD attached. Wouldn't that try start the hole set up process again and wouldn't that fail because no SSD has been attached? Also, I don't quite understand, how updating the boot-loader might possible increase the max ethernet speed.

Is it really still necessary to update the boot-loader? I am totally confused now, I really can't see any connection between the boot loader and the slow eth speed.
  10. The first submenu in "System" is "Freeze".
  11. The only "install" I see in menu "system" is "Install Desktop". If I select that one, it starts to install the full desktop package.
  12. This is strange. Even if redirect the download to the great void with "wget ... -O /dev/null", making sure that no disk is used, the download speed does not exceed 4MB/s, while my PC downloads exactly the same file with 15MB/s. I tried changing the cables, I tried changing IP, I tried changing the router, but all to no avail. I have no explanation for this behaviour.
  13. Please don't get mad at me, but that's what I don't understand: before the switch the system was running on kernel 4.19.62-sunxi After the switch it is now running on kernel 4.19.84-sunxi To me, this is the same kernel branch: 4.19.x. If it was kernel 4.20.x now, or even kernel 5.x, I would totally understand it, but the way it looks to me, it doesn't make sense to me, that armbian-config switches the kernel to a different branch with the same kernel version,while apt-upgrade doesn't.
  14. Hello, What kind of speed can I expect from the ethernet on the BPM1? It's told to be 1Gb/s, but I am not even getting near that speed: wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.4.5.tar.xz ... linux-5.4.5.tar.xz 100%[==============================================================================================>] 104,37M 4,43MB/s in 24s 2019-12-18 22:38:33 (4,35 MB/s) - »linux-5.4.5.tar.xz« gespeichert [109435988/109435988] BPM1 and the router are set to 1000Mb/s, and the download line works at more then 100Mb/s. Downloading the same file on my PC shows a considerably difference: linux-5.4.5.tar.xz 100%[==============================================================================================>] 104,37M 15,4MB/s in 6,9s 2019-12-18 22:43:45 (15,2 MB/s) - »linux-5.4.5.tar.xz« gespeichert [109435988/109435988] Is 4MB/s an average speed for the BPM1?
