Hi Everyone,
We are trying porting a 480x272 LCD to our custom i.mx53 board.
This is our LCD structure in mxc_lcdif.c
...
"0", 60, 480, 272, 111000, 2, 2, 2, 2, 41, 10,
FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
FB_VMODE_NONINTERLACED,
0,
},
.....
We have tried part of this structure and it works on Linux, but when we use it on Android 4.2.2. and Linux 30.35, we see some errors like this: (logcat ouput)

Could you please share your advice about this problem?
Thanks & Regards,
Thank you for your reply, but I didn't understand. You mean that there is no way to use 480x272 LCD on Linux 3.0.35 and i.mx53, isn't it?
Best Regards.
you can use it, but not using gpu.
Best regards
igor
Are there any way to do this, on Android 4.2.2 and Linux 3.0.15? How can I patch for this aim ? Are there any patches, documents, examples or etc?
Could you please share your advice?
Best Regards
Hi David
unfortunately for that kernel version i.MX53 gpu drivers are not supported
as discussed on
