Hello again. Thanks to borderline at
I could install the ZyXEL P-2812HNU-F1 uboot and I can boot into it.
What I did was shortcut the flash pins like described here
https://wiki.openwrt.org/toh/arcadyan/arv7519#bootloader_hack till I
got the VR9 prompt and
then used U -> 0 and uploaded via xmodem the file
With that installed this is the bootlog
ROM VER: 1.1.4
NAND Read OK

*** Warning - bad CRC, using default environment
Hit any key to stop autoboot: 0
Wrong Image Format for bootm command
ERROR: can't get kernel image!
How can I get the information to make a proper .dts file for this
device ? The layout of the flash for the P-2812HNU-Fx has nothing to
do with this device.
