    20.08 upgrade with 5.7.15 will not boot on RockPro64

    in Pine RockPro64

    Posted

    So i will no do the following, correct ?

    After reflash: 

    sudo nano /etc/armbianEnv.txt --> set verbority to 7
sudo apt-get update && sudo apt-get upgrade
armbianmonitor -u --> Garther results
sudo reboot
(and then it crashes)

     

    That’s it ? But then the log crash info isn’t logged ? How do i log the serial output ? I do have an USB to TTL converter.

     

    (sorry for the noobish question, im trying my best)

    I am willing to help i’m however a mechanical engineer not a computer science professional.

     

    Problem is, if i run an upgrade after the flashing is complete my rockpi 4b will perform an upgrade but when i reboot the system crashes. I wont even see a booting output over hdmi.

    I just plug in the power and nothing. So will i be able to even log the error ? I can of course remove the emmc module and mount it and grab an errors file, is that what you are pointing towards me doing ?

     

    If so, can you make a complete noob proof description? I’m happy to help you all out here on the forum.

    Its my own backup image of the EMMc module using dd. It’s a Ubuntu beaver image with all my software and configurations on it. So since its my own tailored image i don’t think its useful to paste the name here :)

     

    Does disableing kernel upgrade even fix the problem? Or does it for example stop the update of uboot?

     

    I was hoping the following would fix my issues: 

    sudo apt-mark hold linux-image-generic linux-headers-generic

    I think im experiencing this exact same problem.

    I was running armbian Ubuntu in my RockPi 4b on a 128 gb emmc module.

    I logged in over ssh and got the message ‘kernel updated please reboot’

    I rebooted and nothing. Not even a flashing red light. No video output.

    Unfortunatley im unable to make big changes to the board now, my house is being renovated and i cant reach my computer stuff.

    Is there maybe a way i can select an old kernel without booting in the system ? Maybe mounting the emmc on a computer and manually editing the grub file ?

    I’m very sad :( Last complete system backup using dd was in april.

    hi there,

     

    I just rebooted my rockpi 4b after a kernel update (i run armbian on emmc). i think this updated really f*cked up the rockpi.

     

    board wont turn on, no output to screen, only green light turns on, have not seen the red light blink since.

     

    i'm pretty sad about this.

     

    Can't supply any more information for obvious reasons.....

     

    time to buy a asus pn50 and just run regular ubuntu. I'm done with SBC with weird hardware.

    RDP failing after cold reboot

    in Beginners

    Ive been doing some digging and it seems that the xRDP service is failed after a reboot: 

    sudo systemctl status xrdp.service 
● xrdp.service - xrdp daemon 
Loaded: loaded (/lib/systemd/system/xrdp.service; enabled; vendor preset: enabled) 
Active: failed (Result: exit-code) since Thu 2020-01-02 19:13:28 CET; 44s ago 
Docs: man:xrdp(8) 
man:xrdp.ini(5) 
Process: 4517 ExecStart=/usr/sbin/xrdp $XRDP_OPTIONS (code=exited, status=1/FAILURE) 
Process: 4509 ExecStartPre=/bin/sh /usr/share/xrdp/socksetup (code=exited, status=0/SUCCESS)

Jan 02 19:13:28 rock systemd[1]: Starting xrdp daemon... 
Jan 02 19:13:28 rock systemd[1]: xrdp.service: Control process exited, code=exited status=1 
Jan 02 19:13:28 rock systemd[1]: xrdp.service: Failed with result 'exit-code'. 
Jan 02 19:13:28 rock systemd[1]: Failed to start xrdp daemon.

    Some googling around revealed that this could be a recent bug in xRDP, more people have been reporting the behavior in the past months:

    Got xrdp

     

    Starting xrdp yields the following output, even after stopping the service first: 

    sudo systemctl start xrdp.service
Job for xrdp.service failed because the control process exited with error code.
See "systemctl status xrdp.service" and "journalctl -xe" for details.

    Journal to log has no info from xrdp, just some login fail from OpenVPN i need to fix.

    Edit: Nevermind the unknown state seems to be normal....

     

    I think there is something wrong with my local host, it’s states as unknown:

     

    ip addr show

        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    Should that be a source of the problem ?

    RDP failing after cold reboot

    in Beginners

    Hi there,

     

    First of all, have a nice christmas. Especially you Igor, im still amazed by what armbian is.

     

    I'd like to ask a question regarding a problem i'm having. Last two days i've been setting up my rockpi 4 as a replacement server. I had everything configured correctly and working. I left the rock on over night and discovered this morning that i couldn' t connect over SSH and vnc/rdp anymore. Since i couldn't connect and the rock was headless i pulled the power an forced a reboot.

     

    After the reboot i could connect to ssh but not over rdp or vnc. My app jump desktop gives the following error: Could not create SSH tunnel. Please make sure tcp forwarding is enabled on the server. Details: Chanel open failure (connection failed).

    The weird thing is, i have not changed anything since the last time, it just doesn't work anymore now so i dont know where to look to solve the issue.

     

    I have the following settings:

    address: 127.0.0.1:3389 (port is forwared in the router and open in ufw)

    ssh tunnel: username@ip_address with private key (also tried username@local ip 192.168.2.150 with key. no effect)

    (ssh is working so the keys or the adresses should not be the problem, tried the exact same keys and both ip as local ip for ssh)

     

    My sshd_config file is in the attatchment. note that i have set allowtcp forwarding to 'yes' as was requested in the error log of jump desktop.

     

    I've also tried re-enabling rdp in armbian-config no effect

    I've also tried running vncserver mp effect

     

    I've hooked up the system to a monitor and it just normally boots to desktop as expected.

     

    Does anyone have some tips where i should start looking for this problem ? I have a hard time doing this since it happened without me interfering.

     

    Thank you in advance.

    Okay I do apologize on forehand.

    Ive tried the following:

    sudo apt-get update

    sudo apt-get upgrade

    sudo apt-get dist-upgrade

    sudo reboot

     

    sudo modprobe g_ether

    modbprobe: FATAL: Module Gether not found in directory /lib/modules/4.4.192-rockchip65

     

    Sudo cat /etc/modules is an empty file (it does exist)

     

    sudo ifconfig usb0 up gives a no such device error

     

    Sudo ifconfig -a doesnt have a usb0 output

     

    Sudo lshw -C network only shows wireless and ethernet connection

     

    cat /etc/os-release

    version = 18.04.3 LTS Bionic Beaver

     

    I think thats all i can do ?

     

    Thanx for the help in advance, greatly appreciated!

    Hey of course I understand! I saw your YouTube video lecture on armbian. I understand this is more of a High-Tier user forum. That's why I also post my question at raxda. I've never complained on this forum, I just experience the other one as 'more kind', that's all, it's my opinion of experience. It was maybe not the kindest thing to say, but hey im not cursing or anything.

    I completely understand where you are coming from. I'm a teacher myself, I teach engineering at a uni (structural mainly, focused on offshore renewables and I also teach a bit of python programming (funny fact, I'm the python expert on my floor)), I have had my piece of 'dumb noob questions' :)

     

    You asked for an explanation, you got one, that's all. No hard feelings whatsoever.

     

    Now let's quit this 'feelings' nonsense and good luck on your crusade with armbian, I hope I can learn from you on the way, I already look forward being a more experienced linux person in a couple of years :)

    I’ve tried the following link. this however didn’t work.

    first of all the file /etc/modules is empty

    whenever i reboot no usb0 interface will come online. 

    Sudo ifconfig -a doesn’t show a usb0 interface

    Sudo lshw -C network  only shows my wireless and ethernet connection.

     

    sudo ifdown usb0 && sudo ifup usb0 yields:
    ifdown: interface usb0 not configured
    Unknown interface usb0
