Follow-ups

--- Cliff Cai 2009-07-09 22:11:34

it works for me.

Cliff

--- Vivi Li 2009-07-29 00:02:50

I can still see this bug happening on regression.

--- Cliff Cai 2009-08-04 03:26:10

I tried it with BF527 v0.2,it seemed Ok.

Cliff

--- Sonic Zhang 2009-08-06 01:40:44

This bug may relate to anomaly 05000380.

Temporary walkaround to 2009R1 is disable DMA for bf527 v0.0 and v0.1

--- Vivi Li 2009-08-06 07:08:43

Yes, it works on BF527 v0.2 but fails on old revision.

--- Vivi Li 2009-08-10 00:30:28

Disable usbhost test in dma mode with BF527-EZKIT 0.0 and 0.1 silicon.

So close this bug.
