HDVPSS Capture Issues

Shaun

Hello,

I'm working with a custom board using the DM8148. I'm using the ti-ezsdk_dm814x-evm_5_05_02_00 with OMX for the capture. On some power cycles I won't get video from the VIP port to the OMX capture component. I'm not sure why this is happening.

During the boot process, I've been getting "VPSS_FVID2: M3 firmware version 0x1000145 is newer,driver may not work properly" when I boot. I've seen the following forum post:

https://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/258126

The suggested solution was to make sure the versions match. I could only find one dm814x_hdvpss.xem3 in the SDK inside board-support/prebuilt-images/dm814x-firmware_05_02_00_48. According to the kernel prints, this is the 0x01000145 version. How do I get the version that correctly matches the driver (0x01000137)

In addition, I'll occasionally get a "I2C: Transfer failed at vps_ti814x_select_video_decoder 188 with error code: -121". I only see it on some power cycles. What could be causing this?

Thanks!

Do you observe this problem when you are using EVM or it is only on your custom board?

I do not have an EVM, just the custom board. I was able to find the matching FW load on the web to address the mismatching issue. The warning about the mismatch is gone now but I am still having power cycles where the capture component doesn't see video. Does it matter if the video is already hitting the VIP port before the OMX software has been started?

Also should I be concerned about the "I2C: Transfer failed at vps_ti814x_select_video_decoder 188 with error code: -121" error?

Hello,

Is this the correct location to get the firmware files?

http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/5_05_01_04/exports/ti-ezsdk_dm814x-evm_5_05_01_04_demo_binaries.tar.gz

I used the hex files in the prebuilt-dir.

Thanks!

Hello,

It seems that you are using EZSDK's version 5.05.02 (first post) but in the last link is pointed 5.05.01 version.

You could check here for the latest ezsdk 5.05.02.
software-dl.ti.com/.../index_FDS.html

When you install EZSDK you could allocate the prebuild firmware in it as well.

I know I am. If you read the post linked above, you will see that 5.05.02 has the newer firmware version with the older driver. I downloaded the firmware from 5.05.01 because Pavel, after consulting internally within TI, said the best solution was to match the versions. Since there are no patch notes to update the driver to match the firmware, I needed to download and use the older HDVPSS firmware.

Also should I be concerned about the "I2C: Transfer failed at vps_ti814x_select_video_decoder 188 with error code: -121" error?

Hello,

What is the command that you are using to load the vpss kernel module?

I'm using modprobe vpss sbufaddr=0xBFB00000

Hello,

Could you try:
modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 i2c_mode=1
