Re: Question about device support

[Florian Feldbauer <florian@ep1.ruhr-uni-bochum.de>]

Hey Michael,

thanks for the quick answer.
Looking at your code, I'm doing in principal the same.
Instead of having a special flag I'm setting PACT = true
as Ralph suggested.

But even when I use your method with the sync flag
I have the same problem:
The device supports updates RVAL of the bo,
but VAL is not changed.
Do I have to set VAL explicitly from device support in this case?

Cheers
Florian
