No sorry, switched to x86 pc and did not spend any time there.

Actually not, I did not spend any more time in the last weeks and still have to buy a serial adapter for debugging. So sorry, I can't help.

Hello, I did flashing again sd card without any changes: And for comparing I read the sd card back to file Attached please find the corresponding readback file. u-boot-meson-readback.bin.gz

Thankx for your help, I am some days on holiday and will respond as soon as possible.

So I wrote your image to the sd card. Both sd card and emmc are plugged in, but after power on the screen stays black, nothing is shown. I need this serial to usb adapter, that's useless in finding bugs. Time to buy :-(

hello, I have prepared a sd card as described and "nulled" it via dd. So I can flash you firmware on spi for testing.

Ok so is there a reason why they conflict each other. I can try you self-build firmware with only u-boot and flash to spi. I have one odroid n2 for experimenting and testing.

I am sorry, I do not have the separate reader to get the serial console information actually. I will also try to find some support in the hardkernel forum how to get things booting. Maybe something else is broken as the updating petiboot via recovery image didn't work at first time and I had to zero the internal flash areas and try again. There was some advise for this in the forum

How to find out the uboot version? I am not using SPI as it is not working at the moment. Don't know why, flashed the latest version and if sd card is inserted it crashes directly to shell if I press a button on keyboard. From package manager I get the following information: ii linux-u-boot-odroidn2-current 22.02.1 arm64 Uboot loader 2022.01 ii u-boot-tools 2021.01+dfsg-5 arm64 companion tools for Das U-Boot bootloader

Hi there, yesterday I tried to use nand install skript tool to move the content from my sd card on odroid n2 to emmc card for booting and using emmc card only. The process itself worked and the content of the sd cards was moved, but after unplugging sd card and plugging emmc card the boot process is not starting and nothing is shown on the hdmi monitor. I compared the /boot filesystems and both are identically. I checked the "armbianEnv.txt" file and it is ok for the new uuid of the emmc card. Everything seems to be identically but why is it not booting. Does someone have a hint what to check additionally what is maybe missing at beginning of the boot process. The LED is not blinking on boot process so something in the first steps of booting and loading does not work. Thank you in advance
