That's what CONFIG_FS_PSTORE_CONSOLE does, see
https://www.barebox.org/doc/latest/filesystems/pstore.html
> Barebox version from within Linux?
Yes, check out /proc/device-tree/chosen/barebox-version
If you are curious what else barebox is fixing up into the device tree,
try of_diff - +
This will apply all DT fixups to a copy of the barebox device tree and
show a diff before and after, e.g.
chosen {
+ barebox-version = "barebox-2021.05.0-20220126-2";
+ bootargs = "console=ttymxc1,115200n8";
+ reset-source = "POR";
+ reset-source-instance = <0x0>;
+ bootsource = "/soc/bus@2100000/mmc@2198000";
};
Cheers,
Ahmad
