Hi I have one of these boards and haven't noticed any degradation in signal ( but unless it was dropping the connection I wouldn't check ) do you have WiFi working on this Buster release?

OK, what is PR ?

Hi all, I'm a bit out of date with regards to a working image for the NanoPi M4 v2 board. I have @pask image which works great but having to boot from the sd card and flash a bootloader patch to eMMC card whenever you reinstall ( I constantly break installs by over experimenting with stuff I don't know enough about ) is a bit of a pain. Anyone know of an image I can just download and flash ?

I think I did try that Martin

Hi all, has anyone managed to get wifi working on the Buster image for M4 v 1 ? Works perfectly with Bionic but I couln't connect at all on the Buster image ( eth0 on physical cable was fine ), using armbian-config lists available networks but is unable to connect ( which is what the error message is )

Found this thread on here and I have sound from the audio jack on M4 v1 not tried V2 yet

It was definitely connected to the internet Nico - and apt install lightdm states that the latest is already installed

Hi Igor, I'm using a Nanopi M4 v1 and running Buster

I'm using the original M4 ( as well as v2)

Hi all, I installed the desktop using armbian-config Install Browser and other but It still boots into a shell - what else do I need to do ?

Thanks for replying but I'm a user not a kernel hacker :-) that stuff doesn't mean much to me - are you saying anything using kernel 5 or above has no sound ?

Hi all, is it ok to run apt update and apt upgrade on @pask M4 v2 image - just thinking something might alter the bootloader

Hi all, I'm using the @pask build for the M4 v2 and all seems good except I am not getting any sound from the 3.5 Jack ( can't try the HDMI as I don't have anything to plug in ) any ideas chaps ?

Hi I only use mine as NFS file server feeding Ras Pi music streamers and have nad no problems been up for about a week now without any problems

Finally got this new board to boot from eMMC - a huge thanks to all on here who guided me. The final missing link was the manufacturer of the board decided to reverse the eMMC connection ( thank you @pask ) It's been a good learning curve though - Big tip of the hat to @pask who built the working image and @martinayotte for sussing the WiFi and other stuff. Now if only someone could get a HiFiBerry DAC hat working on one of these :-)

So you are saying I'm putting the card in the wrong way around ? I'm at work at the moment will try the other way when I get home - thanks guys

Hi Pask, yes definitely in the right way with the long part over the top of the HDMI socket

Right finally I am getting somewhere thanks to yours and others help. I downloaded and compiled the latest version of picocom and was able to use the baudrate stated in pask's post. Powered up the board and no rubbish this time all plain English text. Hit any key and was rewarded with ( I presume ) the uboot prompt of =>. Inserted the eMMC card and entered "boot". Logged in all ok except there was still only one entry in /dev/ for mmcblk*. Tried again with another eMMC card but no good. I'm starting to think both my cards are f****d. But they can't be because I can dd images to both of them.

But I use this cable/adapter on all my other M4 boards without any problems @115200

@chwe

@chwe I tried pasks 1500000 and got invalid baud rate error

Still no joy @martinayotte - to make sure I'm doing things in the correct order this is what I do 1) Make sure the M4 board is powered off and remove the power cable 2) Connect the serial cable 3) Start a terminal on my Linux laptop 4) enter picocom --baud 115200 /dev/ttyUSB0 -- I tried pasks 1500000 and got invalid baud rate error Get this ouput picocom v1.7 port is : /dev/ttyUSB0 flowcontrol : none baudrate is : 115200 parity is : none databits are : 8 escape is : C-a local echo is : no noinit is : no noreset is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv imap is : omap is : emap is : crcrlf,delbs, Terminal ready 5) Apply power to the M4 and immediately press the <spacebar> repeatedly Result is garbage on screen and no command prompt

Thanks @martinayotte I'll give it a go :-)

During the boot process, keep a key pressed: the u-boot loader will stop just before launching the kernel If I press a key the process appears to stop and if I release it and start typing boot I get the login prompt - confused
