Another strange thing is that TEST_CRC_COUNT is 1 at the very beginning even when TEST_SINK is 0. Even forcing TEST_SINK to 0 TEST_CRC_COUNT is still 1. DP 1.2 tells TEST_CRC_COUNT reset to 0 when TEST_SINK bit 0 = 0. This logic works pretty well when PSR is disabled. However when PSR is enabled I’m getting this incorrect panel behavior.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
