Hi Mikko,
I've pushed my changes on https://github.com/openwrt-vgv7519/openwrt
(branch vgv7519-20141007-begin_vmmc)
If you want to try it on different router remember to adjust profiles
and dts like VGV7519.
bootargs = "console=ttyLTQ0,115200 init=/etc/preinit maxvpes=1
maxtcs=1 phym=64M mem=62M panic=1 vpe1_load_addr=0x83e00000
vpe1_mem=2M vpe1_wired_tlb_entries=1";
adjust;
-phym to (memory on your board)M,
-mem to (phym -2)M,
-vpe1_load_addr to 0x(1<<31+phym<<20)
(note that I haven't configured yet some gpio to get voice working
correctly... but I doubt this is the real problem..
>From Daniel Schwierzeck:

>8 1 0 1 CLKOUT0
>34 0 1 1 SSIO_TX
>35 0 1 1 SSIO_RX
>36 0 1 1 SSIO_CLK
So i get firmware load on vpe1 but it crash on worker process.. Do you
know if tapi works on other lantiq cpu with 3.14 kernel?
folowing dmesg...
