Hi I am using EP8548A board based on MPC8548E with u boot 1.2 flashed.

We have done the following experiments for testing the ETSEC loopback test

U-boot erased :

When I test the ETSEC controller for loopback test by initializing the board through code warrior 10.3 using "8458CDS_Core.tcl" initialization script file, the loopback test is passing.

U-boot flashed:

When I do the same initializations for ETSEC through u-boot command prompt, the tests are failing.

Kindly anybody tell us the difference or the initializations done in u-boot (ver 1.2) which is affecting the ETSEC controllers loopback test.

Please find the attached initialization sequence plus loopback test which we have followed for the eTSEC test.
