Summary: MUSB peripheral bulk transfer issues

Details:

From our gadget file storage test, we met some data corrupted issues. And VDSP team also met similar bugs, here is Martin's email:

Hi Robin

As agreed over the phone here is a very brief summary of the problems we

have been made aware of.

1) Stalling. Usually on Bulk transfers. ADA say transfers stall -

awaiting data completion - after 15 hours of successful operation. This

is for IN transfers with Blackfin as device.

2) Data corruption. Sometimes buffers are getting corrupted. Again Bulk

transfers with Blackfin as device. Usually in last 4 bytes of short data

packet. OUT transfers.

3) Again Bulk transfers with Blackfin as device. This time it is that

the Blackfin is receiving less data than expected.

Attached are our latest core module and controller driver.

Martin

First of all, I plan to hook up some bulk IN/OUT pressure test cases to reproduce the issues Martin mentioned.

Then, try to fix them or workaround them. otherwise try to make them recorded as silicon anomalies.

gadget storage harddisk/ram based tests all fail on bf548-ezkit.

We can not find storage device node on PC after gadget storage module is

installed on target board.

Bellow is the log of gadget storage harddisk based test on bf548-ezkit.
