processor locks up after writing to (any) EMMA register

[Daan]

Hello,

I've been trying to get the eMMA to work with the Camera Cog and VC21.
First of all I am missing some registers (Dan, I mailed to
support@VC... for this). Secondly after writing anything to any
register the VC21 stops responding and I have to reset the processor.

Is this a known issue or is this just me being all dumb and such?

(I want to convert the YUV422 from the camera to RGB565 in a sort of
snapshot mode).

Thanks in advance,

Daan Timmer
