Screen problem

[vlad_cool]

I am using armbian on banana pi m2 zero with screen 1920x360. For some reason display controller didn't tell edid, so banana using default value and it doesn't look right (only a few more than half of the screen displaying anything). I want to use this screen, so I want to override default values. How this can be done?

I tried

setenv video-mode sunxi:1920x360-24@60,monitor=hdmi
saveenv

but this didn't work (saveenv tells `Saving Environment to FAT... Unable to use mmc 0:1...`)

and before booting u-boot tells `Loading Environment from FAT... Unable to use mmc 0:1...`

I am using armbian jammy (Armbian_23.02.0-trunk_Bananapim2zero_jammy_current_5.15.80_xfce_desktop)
