Hi Gonzague,

Strange problem indeed. U-boot freeze when I do fatload instruction. After several investigation, the crash appear during the udelay instruction..... But if i replace the original code of udelay instruction by a simple for loop, it works.... Any ideas ?

Does the board freeze or is it really a veerrry long delay? I am tempted to say it is the latter. If you check the archives you will see that there is always a mist of confusion around CFG_HZ and related defines which udelay uses (cpu/arm920t/at91rm9200/interrupts.c).

So I suggest to check the values used there on your platform (CFG_HZ should be 1000 btw.) and find out why udelay spins too long. Having done that, send a patch and rejoice!

Best wishes Detlev
