Message-ID: <4450C352.5642.1365223@localhost> (raw)
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
Udo
