AM335x WEC7 DVSDK

Dear community,

I have received today a brand new AM335x EVM from Texas Instruments.

Build the BSP:

Downloaded & installed the WINCE ARM-A8 02.30.00
Open C:\WINCE700\OSDesigns\AM335X_OS\AM335X_OS\AM335X_OS.pbxml
Switch Configuration to AM33X_BSP_ARMV7_Release
AM335X_OS -> Advanced Build Commands -> Sysgen

Default setup of switches for the AM335x EVM to boot from SD Card:

SW3/SW4 DIP switches: 1111 1101 / 0111 1111
SW6 DIP: All DIP off (0000)

Connection:

Connect Serial Cable to UART0 (next to the power switch)

When I try to play any video, I can hear the sound but the player shows a black screen.

When I enabled debug messages.

Afterwards I tried copying to DVSDK dlls to the FILES directory and the DVSDK .bib and .reg to the platform .bib and .reg and it printed the following messages:

PID:073C0002 TID:0699000A H264: FPS will be printed after every 100 display frames

Has anyone encountered this issue? any idea how to solve it?

Thanks,

Hi Shahal,

The AM335X does not have a DSP on the CPU so you will be unable to use DVSDK to directly access the DSP HW.

Are you able to play videos with the binaries that are a part of the 02.30.00.03 Release?

Regards,

Dear Adeneo Embedded Support team,

Thanks, I somehow missed it at first. However, I downloaded what seemed to be the latest on your site, which was 02.30.00. The images didn't work ( both TI-AM335X-SK-WEC7-BIN-V100 and TI-AM335X-SK-WEC7-BIN-V110) . It hanged after:

jumping to ebootsd image

I built the BSP myself with the following catalog items (in the included file):

7840.SysgenSettings.txt

I can't see any video (as for the codecs I tried h264, mpeg2 and mpeg4 - none worked, I could only hear the sound).

Please advise,

Shahal

Hi Shahal

First about the binaries that you got, those binaries are for a different platform that is called AM335x Starter Kit, that's why you can see the SK as part of the zip file's name. That's why you couldn't boot your AM33x EVM board.

And now about the problem with the video files. Must likely, the reason why you can't see the video being displayed is because the files you're using don't match the video coders that you're adding to your OS image. Even when the video files are supposed to be for an specific format (h264, mpeg2 or mpeg4), it doesn't mean that they have the format that will be recognized by the codecs. I'm sending you one sample file that we used to verify that it was possible to display video and hear the audio 7215.kelsyville_av100.wmv. In our side this file displays the video on the screen and you can hear the audio. We have seen that behavior before, where you can only hear the audio of the file, but no video image. Probably this video will work for you.

Here is again the link to the video file I mention in my previous post.

Dear Adeneo Embedded Support team,

The video did run (although it crushed windows afterwards).

Thank you,
