Hi again,
I guess I misunderstood things a bit. Apologies for that.
Nevertheless, timer_init in board_init_f is pointing to the weak
timer_init in /lib/time.c, which is empty.
Is there a way we can force start the pit timer?
Any pointer would be very helpful. Let me know if you'd like me to do
something in particular.
Thanks

Hi,
So, I put objdump and puts to some good use and could backtrace the
initial error to a udelay call in ddr2_init function on mpddr.c
file.
This function is called from mem_init on
sama5d3_xplained/sama5d3_xplained.c, which in turn is called from
board_init_f on spl_atmel.c.
I couldn't, however, find which timer_init function is being called
here. I still have a few to try, but disassembly gives me a pretty
empty function:
00303690 <timer_init>:
303690: e3a00000 mov r0, #0
303694: e12fff1e bx lr
This work didn't give me many answers, but I got a couple of newbie
questions:
Why is it calling board_init_f from spl_atmel.c and not spl_at91.c?
Isn't the latter the appropriate architecture for this board?
Do you know which timer_init function it is getting here? Could
this
be the reason timer isn't getting probed?
Cheers,
