[SOLVED] How to enable display for AM335x WINCE 7

Hi, 

Only after enabling LCD back light also you will get this screen. Check if you have added LCD driver support in your BSP. If its LVDS1, ensure you have checked the LVDS1 box in your catalog item. And if you have the working driver this should be enough.

Seetharam

Yes in my BSP, there is driver support. but in that file there is one function for Enable the Raster Engine of the LCD Controller.. What does this mean.

and the my bsp ldc driver tree is as:

I am just thinking what should I do with Catalog Modules. Which module I Should select...

Hi,

First check if your LCD/IPU driver is loading. If so, then we will check the driver. Make sure this.

@Seetharam Nayak 

I am very new to WINCE BSP. I have no idea how to determine this thing. means how to check driver is loading or not.....Even that its also not confirmed that Kernel is booting or not... Because i only got the msg that the nk.bin is loaded in ...address... I am sending the console pic....shown below:

In our BSP catalog items, we have a sLCDC Display Driver under Drivers\Display and I have selected this as well as Backlight

Is that all you see on terminal? Start and End of debug prints ? 

Please put complete debug prints. Also print of Eboot menu.

I have enabled retailmsg and added certain kind of pf at the beginning and at the end of some functions of lcdc.c .. But before this i made certain change in Catalog items so this time during the time of booting 4 Square is shown on the screen and after dumping the nk.bin at particular address and jumping to that address, still i got the same 4 diff square colors.... previously it was just diff colors pixels or pink color huge bars for me... What do you think about this....and my console pics are below:--

I feel it's stopping in OAL. Kernel is not loading. Disable KITL if you have enabled it in OS image or in Bootloader menu.

Seetharam

Yes, by default it is enabled..... Still I am searching for disabling it........ Ccan u help me for this where i have to disable it....

First in OS image- > Go to Project properties and checl build options window. You should find KITL enable/disable option, set NO there. Also in bootloader menu, KITL setting should have that setting.

Seetharam

Yes, its under building.. Please wait for next status.......

Still its enabled.....but this time i am getting new thing on console...

PID:00400002 TID:---- SOmeting like this what is this....

Now its going further loading drivers. But something is blocking. 

Check if SYSGNE_HIVE is enabled. If so, disable in catalog items and Sysgen the workspace. 

Search this item in your catalog items list.

Seetharam

No, i don't have SYSGNE_HIVE in register. In place of this I have under Kernel Feature -- Persistent Hive registery Storage SYGEN_FSREGHIVE is enabled by me. Now going to disable and building it........

Still the output is same...........

Are you booting from SD ? Are you sure your workspace does not have Hive enabled. 

None of the drivers loading as far as i understand from your debug log. 

Yes I am booting from micro SD Card and i have already informed you previously it was enabled and after your suggestion i disabled it.... 

Still, I am not able to solve the problem. Please anyone help me to solve the issue......
