[OpenWrt-Devel] Help needed: IP175D + RT3662 issues on a "new" device

[antonio rossi]

Hi everybody,


i'll try to make this as short as possible despite the large amount of information needed to describe the issue:


i am working on adding support for DIR-815 A1, it's a RT3662+RT3092 device with an infamous IP175D switch IC.
i managed to get everything working properly, save for the fact that network (both ethernet&wifi) works only after the stock bootloader does some funky stuff to set up the internal cpu port and/or switch to receive images via TFTP.


this basically means that an initramfs image booted via TFTP works properly, while a squashfs image booted from the internal flash doesn't. 
the boot log from initramfs and squashfs images is basically identical. the switch is recognized and everything. i've tried every possible combination of parameters in the DTS file to no avail. 


it's a pity because the device would be fully working otherwise, which would be the first time in its history because stock FW is bugged as hell and never worked properly in the first place.


here are the bootlog pastebins, both of initramfs (you can see the bootloader setting up something) and squashfs.
any help is appreciated.
