Dear Blackfin uClinux maintainers,
We're committed to support our ADSP-BF527 powered TLL6527M platform with the Blackfin uClinux distribution. I would like to share update summary on our progress so far.

USB Webcam VGA image capture fails: -
Then there is the outstanding issue of capturing images of resolution greater than QVGA using logitech USB webcams, documented here (http://blackfin.uclinux.org/gf/project/u-boot/forum/?_forum_action=ForumMessageBrowse&thread_id=45214&action=ForumBrowse&forum_id=39). This issue has been persisting from 2010R1 and we see the same behaviour on 2011R1. During your 2011R1-RC1 testing and validation, are there any plans to test the USB webcam image capture at resolutions higher than QVGA?
