Summary: gadget zero test failed on BF527-EZKIT in 08r1 branch

Details:

Gadget zero test failed on BF527-EZKIT in 08r1 branch.

It failed when run "testusb -t5" and "testusb -t7" to test bulk OUT transfers.

# sudo ./src/testusb -D /proc/bus/usb/005/019 -t5

unknown speed /proc/bus/usb/005/019

/proc/bus/usb/005/019 test 5 --> 32 (Broken pipe)

# sudo ./src/testusb -D /proc/bus/usb/005/019 -t7

unknown speed /proc/bus/usb/005/019

/proc/bus/usb/005/019 test 7 --> 32 (Broken pipe)

Follow-ups

--- Bryan Wu 2008-05-21 00:01:28

Broken pipe message is an errno which means the host PC received the STALL from

BF527 USB peripheral.

These 2 test cases tried to send out all-zeroed BULK out packet to BF527. The

g_zero module will check the data from host. But some none zero data was found

then g_zero asked BF527 to send STALL to host. The test cases failed.

I found the none zero data always is 190 (0xBE), but it is very strange I

cannot capture this 0xBE with the Lecory USB analyzer.

And the none zero data appears randomly. If I increased the debug level to 7 of

the MUSB driver, this issue is gone.

I also found this bug in BF548 when config BF548 musb to use PIO mode not DMA.

So this issue should relate with the PIO mode operation.

And in PIO mode, I got lots of turnaround time too long or response completely

missed error with the Lecory USB analyzer.

Is the insw and outsw problem?

With Sonic's help, we fixed this bug. I will check in the code to branch first,

then test it on trunk and send out the patch for upstream.

Fix it again by enabling DMA for read_fifo operation.

OK now. Close it.
