Dear OpenWRt list,
Dear Martin,
Dear Hauke,
TL;DR:
Can you help me out with the DTS? I have no access to datasheets and I couldn't
recover useful infos from the original firmware...
Attached my DTS
I am still trying to port a FRITZ!BOX3272 device to OpenWRt.
I tried to grab as much informations as I could, but I am arriving to the
conclusion I hould be doing something really wrong.
First of all, the kernel panics due to a data abort at
linux-4.19.66/arch/mips/lantiq/xway/sysctrl.c, line 478
/* make sure to unprotect the memory region where flash is located */
ltq_ebu_w32(ltq_ebu_r32(LTQ_EBU_BUSCON0) & ~EBU_WRDIS, LTQ_EBU_BUSCON0);
Secondly, commenting out this line just to see how it goes, I can see the
kernel fails to communicate with the PMU - and...
