I found this bug a while ago and have finally gotten around to looking at it because I needed its service.
In previous posts to this email list, Wolfgang had mentioned that the "time unit" returned by get_timer() is 1 msec. Close examination of interrupt_init_cpu() at cpu/ppc4xx/interrupts.c suggests a timer interval setup of 10 msec!
I think you are right.
I've tested the following and propose it as a fix, replace this: val = gd->bd->bi_intfreq/100; /* 10 msec */ with: val = gd->bd->bi_intfreq/1000; /* 1 msec */
I've also tested some of the network related functions to insure that no timeout conditions have appeared.
I want to post this patch but would prefer a code review from those that are more familiar with get_timer() use within the OCOTEA codebase.
I don't know why the 440 is handled separately.
Stefan, do you have an idea?
Best regards,
