I think the error -22 is for invalid parameter. the previous u-boot is sending a bad parameter for loading the kernal. so when a HDMI is needed it shows the error. After changing the U-boot the error is not showing as well as the HDMI is working properly.</P><P>Thanks</P></BODY></HTML> Tue, 19 Apr 2016 10:23:27 GMT https://community.nxp.com/t5/i-MX-Processors/HDMI-Video-is-not-ready/m-p/484260#M77274 nirmaltm 2016-04-19T10:23:27Z
