Hello:

Does anyone know why:
when I set TSTART to start sending data,then poling TSR register to wait for TCOMP, but the TSR register always TGO(transmit go), what's this means? and any suggestion?

Thanks!

A 9260? not an ARM7TDMI right?

When things get stuck you should verify that you have enabled all the clocks for the peripheral, and that external clocks from interfaces are present and wired correctly.

Make sure you have initialized everything properly, and the design is wired correctly.

I have test EMAC on ADS, without OS, all works.
Now I am using vxworks, I follow all initialization and operation step,
but the TSR register still TGO.

PIO setting, pcer clock, reset PHY & nego all finished,
any suggestion?
thanks
