pkfox Posted December 20, 2019 Posted December 20, 2019 Hi guys , I installed the Buster WIP image on my M4 V2 and it appeared to be functioning ok wifi,USB etc all working until this morning. It wouldn't boot so I connected a serial cable and saw where it failed ( I think it part of the uboot process) ERROR: Did not find a cmdline Flattened Device Tree Any ideas why this should suddenly happen ? I have two V2's running this build and the other is still working fine

Did you by any chance upgade all the packages (apt upgrade) on the one that does not boot anymore? I cannot verify it now but one thing that comes to my mind is that the kernel upgrade overwritten device tree files and m4v2's u-boot points to a file that is not available in the official 19.11.3 kernel package. If that's the case you could use armbian-config to freeze the kernel and still be able to upgrade the rest of the packages.

Hi @piter75 I think I might have done :-( thanks - Do you mean select Freeze in armbian-config ?
