Hello,
inside of arm_init() in the part:
/* MII management start from here */ if (!(p_mac->EMAC_SR & AT91C_EMAC_LINK)) { if (!(ret = PhyOps.Init (p_mac))) { printf ("MAC: error during MII initialization\n"); return 0; } } the software checks the status of a LINK-Bit. I thing the EMAC_SR register is wrong, because the EMAC_ISR has this valid LINK bit (AT91C_EMAC_LINK on bit 9).
Did anybody find this problem? If not, so I will check it with our hardware and then I will prepare a patch.
Thanks and Regards
