Touch issue on i.MX6 Android Dual display

kirangv — Wed, 24 May 2017 07:48:13 GMT

Hi,

I am working on i.MX6Q SARBE AI board with HDMI and LVDS display.

I have made change to "6x_bootscript_android.txt" to make HDMI as primary screen.

But after the change if i touch on HDMI screen the contents on LVDS is getting changed. The touch input from HDMI is going to the contents of LVDS.

Do i need to do some other modification in case we change primary display , please help ?

Modified "6x_bootscript_android.txt" :

------------------------------------------------

${dtype} dev ${disk}

setenv bootargs enable_wait_mode=off
setenv nextcon 0;
setenv bootargs $bootargs console=ttymxc1,115200 vmalloc=400M consoleblank=0 ;

if hdmidet ; then
setenv bootargs $bootargs video=mxcfb${nextcon}:dev=hdmi,1280x720M@60,if=RGB24
if test "0" -eq $nextcon; then
setenv fbcon "fbcon=28M";
else
setenv fbcon ${fbcon},28M
fi
setexpr nextcon $nextcon + 1
else
echo "------ no HDMI monitor";
fi

i2c dev 2

if i2c probe 0x04 ; then
setenv bootargs $bootargs video=mxcfb${nextcon}:dev=ldb,LDB-XGA,if=RGB666
if test "0" -eq $nextcon; then
setenv fbcon "fbcon=10M";
else
setenv fbcon ${fbcon},10M
fi
setexpr nextcon $nextcon + 1
else
echo "------ no Freescale display";
fi

if i2c probe 0x38 ; then
setenv bootargs $bootargs video=mxcfb${nextcon}:dev=ldb,1024x600M@60,if=RGB666
if test "0" -eq $nextcon; then
setenv fbcon "fbcon=10M";
else
setenv fbcon ${fbcon},10M
fi
setexpr nextcon $nextcon + 1
else
echo "------ no 1024x600 display";
fi

if i2c probe 0x48 ; then
setenv bootargs $bootargs video=mxcfb${nextcon}:dev=lcd,CLAA-WVGA,if=RGB666 tsdev=tsc2004 calibration
if test "0" -eq $nextcon; then
setenv fbcon "fbcon=10M";
else
setenv fbcon ${fbcon},10M
fi
setexpr nextcon $nextcon + 1
else
echo "------ no 800x480 display";
fi

while test "3" -ne $nextcon ; do
setenv bootargs $bootargs video=mxcfb${nextcon}:off ;
setexpr nextcon $nextcon + 1 ;
done

setenv bootargs $bootargs fbcon=$fbcon
${fs}load ${dtype} ${disk}:1 10800000 uImage && ${fs}load ${dtype} ${disk}:1 12800000 uramdisk.img && bootm 10800000 12800000
echo "Error loading kernel image"

Thanks,
