Strange behavior is not it ;-) I have seen this before and it was due to a bad timing setup of the dm9000 chip select. - at91_sys_write(AT91_SMC_CYCLE(2), AT91_SMC_NWECYCLE_(0) | AT91_SMC_NRDCYCLE_(16)); + at91_sys_write(AT91_SMC_CYCLE(2), AT91_SMC_NWECYCLE_(16) | AT91_SMC_NRDCYCLE_(16)); Is you have the first configuration, try with the second and it should fix your problem. Hope that it helps. Tell us if it works.
