CryBaby

Install nodm.

I also had problems with cifs (on OSMC which is debian based like armbian). Using sshfs works well though: share@ccb-adm035:/home/share /mnt/ccb_adm035 fuse.sshfs noauto,x-systemd.automount,_netdev,users,idmap=user,follow_symlinks,allow_other,reconnect 0 0 You need to have sshfs installed. Check you can ssh to the remote machine and ssh-copy-id to it so it doesn't need a password.

The problem is a bug in the xserver, not your HDMI to VGA unit. The bug has been fixed but the fixed version has not yet reached the standard repos. Voka is offering a version of Armbian which includes the fix. That is a good option if you have not invested much effort in configuring your existing install.

I just did a firmware update and got xorg 1.20.13 but it still does not work. Looks like we'll have a wait a bit longer for the next version. @Nico: if you Ctrl-Alt-F2 you will get a login prompt. Once logged in you can type sudo armbian-config and under System->Firmware do a full update. Try this once a week until things improve

I have been following Quartz64_Development as I believe it will also mostly apply to RK3568 support. If I interepret it correctly almost everything needed will be in kernel 5.16 except VOP2 which is necessary for HDMI output. So a headless Armbian is probably feasible.

A simple sudo apt install. I had that error before I installed it, after I get AIGLX: Screen 0 is not DRI2 capable. I assume this would be fixed if I installed the mali blob. I still have the original X.Org X Server 1.20.11, maybe you have a different one?

I found I get a desktop if I install xserver-xorg-video-fbturbo. The performance is pretty poor though. Is this still the preferred option or has it been superceded? To answer my own question for the record: fbturbo uses ARM's mali blob for acceleration, which I don't have hence the poor performance. Recent xorg works with lima and doesn't need the blob. So the correct solution to this problem is to wait for xorg-server 21.0.99.1 or newer to become available in Armbian.

I just tried Armbian_21.08.1_Cubietruck_focal_current_5.10.60_xfce_desktop.img The desktop is still not working, just a black screen on HDMI. I posted the armbianmonitor output here if anyone wants to look at it. There's some lima errors. There's also some bluetooth errors. $ sudo bluetoothctl show Controller 8A:AB:7E:0F:6F:FB (public) Name: cubietruck Alias: cubietruck Class: 0x001c0000 Powered: yes Discoverable: no DiscoverableTimeout: 0x000000b4 Pairable: yes UUID: Message Notification Se..

Done.

Thank you balbes150, my P2 is running nicely with your image. I would like to get DVB running too but the modules don't seem to be included (my DVB tuner is listed by lsusb). So i'm trying to build the kernel myself. I am following https://docs.armbian.com/Developer-Guide_Build-Preparation/ using https://github.com/150balbes/build but it doesn't offer any rk3568 kernel options. What else should I be doing?

Usually u-boot will pause briefly to allow you to interrupt it by hitting Enter or Ctrl-C (either on the console or serial terminal). You then get a command line. The boot order will be set in an 'environment variable' which you can view, edit and save. Useful commands are printenv, setenv, saveenv and help. The most interesting environment variable is bootcmd which you probably want to change to 'sdcard'. I think you are specifying a function here rather than a device so it will depend on what functions are available. I would not assume that there is a boot order by default. If not then an empty eMMC might just mean no boot. It might even mean no u-boot. I believe Station OS is a version of Android. If there is an app store maybe you can install an ssh server or terminal program from there. Alternatively, you may be able to get a shell using ADB from your PC.

Perusing the wiki again I get the impression that booting from the SD card is not something they expect people to do. The instructions are for using it to upgrade the firmware, ie. overwrite the eMMC with a new OS. The images they provide may therefore not be bootable. On the other hand I just noticed an "SD Boot" option in their firmware upgrade tool. You might experiment with that, if you manage to download it.

The wiki vaguely describes a procedure for installing Ubuntu, the images are provided here: http://en.t-firefly.com/doc/download/94.html My P2 arrived today. Unfortunately I am in another country entirely and will be for about a month, or longer if Covid has its way. So let us know how you get on with it.

Looks like it has moved again: /sys/power/axp_pmu/ac on Armbian 21.08.0-trunk.77 Focal The old battery info is at /sys/power/axp_pmu/axp20x-battery-power-supply/power_supply/axp20x-battery "A foolish consistency is the hobgoblin of little minds."

Nah, using brcmfmac43362-sdio.bin and brcmfmac43362-sdio.cubietech,cubietruck.txt from linux-firmware with no hcd gives a (non-functioning) controller on cold boot only. Adding in ap6210/bcm20710a1.hcd gives no controller. Also, none of the 54 hcd files from github match ap6210/bcm20710a1.hcd I don't know what to try next.

I have the same one: /lib/firmware$ strings ap6210/fw_bcm40181a2.bin | grep 43362 43362a2-roml/sdio-g-pno-pktfilter-keepalive-wapi-wme-p2p-*unknown* Version: 5.90.195.0 CRC: b99a439d Date: Mon 2014-03-10 15:00:57 CST /lib/firmware$ ls -la brcm/brcmfmac43362* lrwxrwxrwx 1 root root 27 Jul 21 07:05 brcm/brcmfmac43362-sdio.bin -> ../ap6210/fw_bcm40181a2.bin -rw-r--r-- 1 root root 1121 Jul 20 21:15 brcm/brcmfmac43362-sdio.cubietech,cubietruck.txt $ dmesg | grep -iE "bluetooth|bcm|brcm|uart|firmware" [ 12.799205] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip BCM43362/1 And it seems to be using it. I think we've established that we can load what we think are the right firmware files, either by the new kernel style or the old userspace style, and it all looks fine (to the best of my knowledge, such as it is) but it still doesn't actually work. I'm gong to try the linux-firmware files again. I suspect I may have screwed up before.

I removed the bluetooth stanza from the dt. Installed CT_Bluetooth and rebuilt the binaries. Set it to use /dev/ttyS2 and the systemd service from here. I had to link the hcd from ap6210/ to brcm/ to start the brcm40183-patch.service then I got a controller: $ sudo systemctl status bluetooth ● bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2020-07-22 20:54:40 CST; 5s ago Docs: man:bluetoothd(8) Main PID: 1938 (bluetoothd) Status: "Running" Tasks: 1 (limit: 4553) Memory: 1.3M CGroup: /system.slice/bluetooth.service └─1938 /usr/lib/bluetooth/bluetoothd Jul 22 20:54:40 truck1 systemd[1]: Starting Bluetooth service...

My phone is not detected and it doesn't detect the cubietruck.

Using ap6210/nvram_ap6210.txt loses the controller again. Using ap6210/nvram.txt and the newer brcmfmac43362-sdio.bin from linux-firmware has a controller after a cold boot but not after a warm boot.

To summarise: It doesn't look like removing the reset from the dtb helps. Using the WiFi firmware and NVRAM from ap6210/ gives us a controller even after a warm reboot. Using the hcd from ap6210/ takes it away again although its log messages look better. No device detection yet.

I'll give it a go when I get back from work in about 9 hours.

A cold reboot and the controller is back, and the RFCOMM messages. It still does not see my device though.

It still doesn't find my device even with a full charge and it sitting on top of the cubietruck. I did an apt upgrade and reboot. Now there is no bluetooth controller again. The RFCOMM messages are gone too. Either the upgrade broke something or there is an element of luck involved.

I thought I'd better start with a fresh install. Armbian_20.05.4_Cubietruck_focal_current_5.4.45_desktop.img same as before. I set up locale and other basics using armbian-config. I disabled the desktop and installed bluetooth. I did not install full firmware or do an apt upgrade. I didn't mess with the firmwares at all.
