boot logo

Hi,

I have one question. I can display the bootlogo on HDMI and HDCOMP ports, but when the program starts to enter the kernel, the image of HDCOMP will disappear. Is it possible to keep to display the bootlogo on HDCOMP?

Are you using DVR RDK ? If so which version.

Hi,

In the Linux Kernel, pinmux settings for getting hsync/vsync output from HDCOMP are getting reset at the boottime. This could be the reason for logo getting disappeared for HDCOMP. Could you make sure that this pinmux setting is not channged.

Specifically, change the signals tsi5_bytstrt, tsi5_pacval to OMAP_MUX_MODE1 instead of OMAP_MUX_MODE2 in arch/arm/mach-omap2/devices.c file.

Brijesh Jadav,

Thanks for your reply. Both signals tsi5_bytstrt and tsi5_pacval are OMAP_MUX_MODE1.

My RDK version is 03.00.00.00

Hi Jack,

I think the display itself is stopped, then only VGA output will be off. Do you see hdmi working still? Can you take dump of 0x48108000 address and share it?

Hi Brijesh,

When VGA output stops, HDMI is working still. The value of 0x48108000 is 0.

If this register is set to 0, it means venc is stopped, you will need to find out who is resetting it to 0.

Hi Brijesh,

I have the same problem.

I use "logo on 0x81000000 0xA0000000 0x81600000 40 60" in the bootcmd of the uboot.

Logo display on VGA output will stop when kernel start booting...but HDMI is ok!

The value of 0x48108000 is 0x44032033

Is venc stopped?

When I use "nand read 0x81000000 0x280000 0x300000; logo on 0x81000000 0xA0000000 0x81600000 40 60" in the uboot prompt.

Logo display on HDMI and VGA output is all ok. But both will stop after about 15secs. Why? Does logo have display time?

Thanks

Steven

Hi Steven,

As i said in earlier post, it could be because of pinmux getting reset. Please check your pinmux setting.

Yes, Logo has definate display time. The last value in the below command, 60, is the number of seconds, logo will be displayed.

logo on 0x81000000 0xA0000000 0x81600000 40 60
