Seiko WVGA Panel with iMX53 Start Board

[Roshni]

Hi All,

I am working with the Quick Start Board evaluation board with a Seiko 4.3" WVGA Touch Panel LCD connected to the Expansion Port (J13). It doesn't show any startup image nor does the boot up process detect the LCD...

Following are the boot params used:

setenv bootargs_base ‘set bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB24,SEIKO-WVGA

Is there anything else specific I need to do to enable the LCD Panel? Please let me know if you need any further information to better understand the problem (eg: Kernel Boot log, Uboot params etc)

Any help will be greatly appreciated. 

Thanks,
Roshni

Hi,

I am using the MCIMX53QSB. In following you can find the LOG Details.  Also Please view the attached Schematic of LCD. Let me know whether the patch is updated or not. I am using the latest BSP.11.09.

Please Find the attachments :

1.) env variables.

2.) log.text

3.) schematics of LCD

You have seen this notice as you have enabled OTG driver for mx53 LOCO board
For mx53 loco board, the OTG function is unavailable due to hardware limitation
So, Only one usb function (device or host) can be available for certain image
Please config your kernel to disable OTG and the usb function you don't want to use
And remain the other usb function you would like to use

Below OTG configs should be removed:

Choose one of below configs for host or device function
But DO NOT choose them together

I haven't ordered my iMX53 Quick Start Kit with touch screen LCD display yet, but I'm keen to look at the interface pcb logic before it arrives.  I have down loaded the i.MX28 LCD Design Files:Hardware Schematics but there doesn't appear to be any logic on PCB.  Can you please post/sent me a full photo of the PCB that is attached to the Seiko 4.3" WVGA Touch Panel LCD.  Thanks and Happy New Year.

Hi Roshni,

it looks like you've got earlier release of the board. Small modification is required on the LCD board to get it working. See attached. On Rev C boards this is not needed.

Hi,

We also had problems identifying key presses with the MCIMX28LD Sieko LCD supplied with the  imx53 Quick Start Board.

We could not identify key presses and were unable to calibrate the LCD using tslib ts_calibrate.

We found using tslib ts_print_raw test that the x and y coordinates were fine but we were getting no indication of pressure from the kernel.

We found that da9052_tsi.c touch screen driver never sends any indication of pressure to user space.

I attach a patch to the kernel that fixed this problem.

Regards,

Shlomo Kut

Did you install tslib from ltib? what happens when you run ts_calibrate or ts_print_raw? You need to export TSLIB_TSDEVICE env. variable to correct touchscreen device as well...

Regarding touchscreen it doesn't work in single-display configuration too. I see the driver is loaded and I see some event debugging messages coming from /dev/input3/eventX in dmesg too. But nothing on touch screen comes up. Is there a way I can enable touch screen calibration? Maybe that's the reason why its not working. I tried giving a command line argument of calibration, but I did not get a /etc/pointercal. Any thoughts will be greatly appreciated.

Hi Vladan,

I narrowed down the issue of dual display to a memory corruption in the driver - ipu-disp.c (ipu_init_sync_panel). I am not sure of the procedure, but I can send you a patch / explanation for it. After I made the appropriate change, dual display is working now.

Thanks a lot for the schematics and your prompt reply.

Hi Roshni,

I'm not sure on exact syntax for enabling dual displays right now, may be you'll have to do it from command line. Schematic for MCIMX28LCD is attached.

Does touch screen work in single-display configuration? Can you see the driver is loaded and is any kind of event generated on /dev/input/eventX ?

Hi, 

I was successfully able to play a 1080P / 720P Video working with following options (single Video mode):

setenv bootargs_base setenv bootargs console=ttymxc0,115200 video=mxcdi1fb:YUV444,TV-1080P30 di1_primary tve

Now I am trying to get dual display and touch screen working with the following options: 

setenv bootargs_base setenv bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB24,SEIKO-WVGA video=mxcdi1fb:YUV444,TV-1080P30 di1_primary tve

Every time I un-blank the LCD display, my primary display (a 1080P TV in my case) says un-supported mode, following which I can never get anything to display on my Primary display. I referred to the imx53-start-linux.pdf document and it tells that "D4 needs to be populated for Seiko LCD Panel" Pg 11-1. 

1. Do I have to populate D4 also for Dual Display to work?

2. Where would I find the Schematics of MCIMX28LCD? 

3. Touch screen also doesn't work, do I have to do anything special to get that to work? 

Any help will be greatly appreciated. Thanks a lot for your time. Please let me know if you need any other information.

Best Regards,
Roshni

Thanks for your prompt reply Vladan. I greatly appreciate it. I will try the mod tonight will let you know. 

Thanks a bunch again.

Hi Vladan, Thanks for your quick response. I have Rev B of the board with following information on the board: SCH -26565 Rev B 700-26565 Rev B TDA 3737 Please let me know if you need any more information. Thanks for your help Roshni

Hi,

what is the revision of the Quick Start Board you have?
