Subject: [U-Boot-Users] quit unclear code in cpu/arm920t/at91rm9200/ether.c Line:220

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
