I'm testing the ethernet loopback test on POWERPC 460EX canyonlands Board. I'm making the ethernet loopback mode by programming the phy control register.(mii w 0 0 5140)
Then i'm running the ethtool command.
"ethtool" command? This is not part of U-Boot.
But it is showing "loopback test failed". I have gone through the code whatever i have patched, as per my understanding it is correct.
can any one suggest me correct solution for this..! or if u know the another ethernet loopback test method kindly suggest me..!
I suggest that you take a look at the POST (Power On Self Test) framework. It has support for ethernet loopback test for PPC4xx. E.g. board sequoia. Look for CONFIG_SYS_POST_ETHER and take a look at the following file:
post/cpu/ppc4xx/ether.c
