The system is starting in to init after this error. but the HDMI is not working.

I have gone through many post regarding the same error. but the result is same. when I change the boot configuration as :

mxcfb0:dev=hdmi,1280x720M@60, if=RGB24.

The system is stuck while booting. the kernal is not loading in this time. I think the system suspend the console

So, i have added the consoleblank=0. but the result was same.

kindly help me to resolve this problem.

Hi all,

Thanks for your help, the problem is solved by changing the u-boot by newer version (uboot-imx-imx_v2015.04_3.14.52_1.1.0_ga). 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.

Thanks

Hi Nirmal

could you run cat /sys/class/graphics/fb0/modes

to check what modes are supported. Also if HDMI is enabled

in u-boot, could you try to disable it in u-boot.

Had you tried with 1920x1080 HDMI  and other monitors?

Best regards

igor

2. HDMI is disabled in u-boot

the result was same. we got an HDMI error while kernel loading.

3. Tried with different monitors with Full HD as well

but the result was same.

kindly help me to avoid this HDMI error
