Summary: gadget zero control may hang at test 14 in bf548-ezkit

Details:

 

Gadget test in bf548-ezkit is not as stable as in bf527-ezkit.

For example, gadget_zero test may fail at test 14 occasionally, and it's hard to reproduce.

bf527-ezkit has better result and gadget test always pass.

Trunk and 09r1 branch has the same problem.

mm,it seems that the workaround provided by hardware guys is not stable on

BF54x.

Bob needs to send email about the issue of the workaround to hardware supporting

engineer at processor.support@analog.com.

Updated Host OS's kernel from 2.6.25 to 2.6.31.

This bug disappeared.

Update kernel and can't see this bug now.

So close it.
