after a lot of tests I 'm still not able to get it work.

Just the first step:
tftpboot openwrt-ipq807x-generic-dynalink_dl-wrx36-initramfs-uImage.itb
bootm
...

after that i get
'OpenWrt SNAPSHOT, r22438-d98c4fb8bf'

but from there I'm lost.

I'm happy for any help

Did you actually try setting the real offsets and sizes of the rootfs partitions? Since this device has a substantially different flash layout comparing to the DL-WRX36.

Also, when the DL-WRX36 partitions add up to 253M (which is just 3M shy of the total 256M),
