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 to LEDE/OpenWRT 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 when the bootloader receives something via TFTP then any image booted (either initramfs or from flash) works properly, while a squashfs image booted from the internal flash (so the bootloader does not set up cpu port/switch) doesn't. the boot log of working and non-working states are basically identical. the switch is recognized and everything. i've tried every possible combination of parameters in the DTS file to no avail. I also investigated GPIO pins, but the only pin that has somewhat of an effect is GPIO24 which is connected to the switch reset pin, and it has no effect on the issue itself (it just resets the switch that then needs to be reconfigured with the vlans and such) What catches my interest are those few lines from the bootloader that says 1.set ge1 as normal mode 1.set ge1 as mii mode enable turbo mii Using Eth0 (10/100-M) device i am guessing ge1 refers to the gigabit ethernet cpu port and the turbo mii, well, i can't set that mode, just normal mii. it's weird because changing phy-mode in the DTS actually affects the cpu port and switch but there is still something missing to make it work without bootloader/stock rom intervention. here are the bootlog pastebins, both of working and non working state (in this order). any help is appreciated. http://pastebin.com/rNwewZ8J http://pastebin.com/Gw9DNfFZ here is the DTS http://pastebin.com/iLSbw9gJ here is the swconfig output (identical in both working and non-working state) http://pastebin.com/iBK47i9m best regards, Bracco _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
