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,
