imx6dl uboot doesn't show logo with hdmi after patched

conteczxy · ‎06-25-2015

My environment: imx6dl, JB4.2.2_1.1.0, hdmi, 1920x1080, RGB24

I applied the patch "Patch to support uboot logo keep from uboot to kernel to Android for JB4.2.2_1.1.0-GA and L3.0.35_4....",

and test with lcd, it works well.

Now, I am testing with hdmi,

Changes I did as follows,

uboot-imx/include/configs/mx6dl_sabresd.h

1.

370 #define IPU_OUTPUT_MODE_HDMI

371 // #define IPU_OUTPUT_MODE_LVDS

372 // #define IPU_OUTPUT_MODE_LCD

2.

381 #ifdef IPU_OUTPUT_MODE_HDMI

...

421 #define IPU_NUM 1 // original set to 2

I changed IPU_NUM from 2 to 1, because there is only 1 ipu in imx6dl, I think it should be changed

and

if I use #define IPU_NUM 2

the system will halt on uboot, log as follow,

else if I use #define IPU_NUM 1

the system will start up, but on hdmi, it shows "no siginal input"

3. my KERNEL_CMDLINE is as follows:

Does anyone know what is the problem with my case?

Thanks

Hello Qiang_FSL, this customer also posted his question as a comment of your referenced document.

Do you have any comments for this case?

Best regards!

HDMI display on IPU0 cause hasn't been given in that patch, but I think is is each to porting. I had given enough example for such kinds of porting.

Hi Qiang,

I am using i.MX6 dual lite processor.

I have applied the patch "L3.10.53_GA1.1.0_uboot_logo_keep_patch_2016-01-04" and build u-boot,uImage and dtb file.

I am using MFGTool to flash my binaries into eMMC. i have added below line in ucl2.xml file for loading logo image to eMMC

<CMD state="Updater" type="push" body="send" file="files/logo.bmp">Sending logo.bmp</CMD>

<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mmcblk%mmc%p1 bs=1 seek=1048576 skip=54">write logo to sd card</CMD>

But by adding these lines now u-boot is not able to find the uImage, I think I have corrupted the uImage by adding these lines.

So can you please guide me what will be the proper way of loading logo screen to eMMC.

Also, after adding the patch my kernel crashes with the below logs:
