Re: Re: setting values to CICR2 register in PXA320 Quick Capture Interface




Hi Florian,

first: Thanks for your answer!

Do you know, if actually somebody works at this point? I asked google, but it didn't find a newer driver for a PXA-Camera.
I also had the chance to look at the Documentation of the PXA270, and it isn't as detailed as the one for PXA320, but the register also exists and has the same hardware address. So the "old" driver would work for me so far, if there would be a way to set the register.

regards
Judith
