i.MX6Q Android 6.0.1 HDMI re-plug issue

[m_c]

Customer found i.MX6Q Android 6.0.1 screen will became weird (HDMI-display-weird.jpg) and console show error message (HDMI-error-console.jpg) after plugin/out HDMI cable several times. However, this issue isn't easy to duplicate manually . So customer use another way to duplicate with below command (HDMI-error-console.jpg). Then screen will became weird and show error message same as plugin/out HDMI cable serveral times manually. If change mode back, the screen will became normal (HDMI-display-re-change.jpg), but with flick and mouse cursor lag, and error message (imx6.gralloc: FBIOPAN_DISPLAY failed: Invalid argument) still keep print.

Hardware: MCIMX6Q-SDP

Software: Android 6.0.1

echo "V:640x480p-60" > mode

logcat -c

logcat

Hi Diego Adrian Cuevas

Is this problem solved?

Hello,

I apologize for the delay.

Unfortunately, the problem is still not solved, I am still working on that. It seems to be a problem with a buffer overflow. Please give some time. I apologize for the inconveniences this is taking to you.

Best regards.

Diego.

Hello,

Just to inform you about the updates.

I tested also with the Android 7 version. But apparently, the commands that you are using does nothing to the Android image output. Can you please see if that version solves the problem that you have?

Best Regards,

Diego.
