I can't boot into image

[chabulhwi]

I’ve just flashed Image-55 and managed to log into Debian using the 1-bit QSPI NOR FLASH mode. But I can’t update U-Boot.

@Bertcay

As expected, image55 (v2.3.0) was not able to mount mtd devices then switched to the other solution (flashing through TFTP server).
As expected too, using image69 without updated u-boot & SPL failed booting and forced the boot to u-boot. From here the tftp procedure worked fine for updating u-boot and SPL
→ Reboot : debian booted directly.

Thx
