Hi ,

We have a MCF5485 procesoor based custom board. But it's design is derived from M5485EVB board. 10% of boards are having TFTP download issue. TFTP donwload is getting failed. It has the boardcom BCM522 as PHY interface. we are using FEC0 of MCF5485. TFTP dowload is always getting failed while downloading Linuix kernel image. All the ethernet settings were intact, as rest of our boards are working good wit the same settings.

Can anyone have any idea ?

Boot log detials:
