[OpenWrt-Devel] lantiq vr9 and fxs

[Eddi De Pieri]

Hi to all,

I've applied to kernel patch for vpe committed for falcon, fixed for
vr9 ltq-vmmc, modified VGV7519 dts for passing new parameters

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

Now I get:

It seems kernel crash on

   /* copy FW image to base address of CPU1 */
 IFXOS_CpyFromUser ((IFX_void_t *)cpu1_base_addr,
                          (IFX_void_t *)pFWDwnld->data, pFWDwnld->length))


Any suggestion?
