I bought  MCIMX6QP-SDB recently.

I am trying to connect HDMI monitor to J8 on MCIMX6QP-SDB.

 

I used the following BSP(u-boot-2018-03, linux-imx-4.9.88).

  repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml

..

  bitbake fsl-image-qt5-validation-imx

 

I tried the following both kernel commands on u-boot.

  setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} rootwait rw video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32'

and

  setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} rootwait rw video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'

 

The monitor and the HDMI cable have been tested with PC. but HDMI display didn't work. 

I saw the following hdmi error message and imx6qp chip was getting very hot.

mxc_hdmi 20e0000.hdmi_video: same edid

 

Should I do change more configuration except changing kernel command on u-boot?
