Linux/AM5708: error to save encode file of vivid using g streamer.

Hello Nikunj Patel,

What you are using EVM or custom board?

Gstreamer point of view the pipeline is fine but the error that you are observing seems like ipu2 firmware is not loaded.

What is the output of this command:

ls -l /dev/rpmsg* . This should shows /dev/rpmsg-dce.

If this does not exist please search for dra7-ipu2.fw.xem4 in /lib/firmware.

You may refer the below thread:

Dear Margarita,

We are using our custom board.

Please check the output of below command. my board does not have created a link of /dev/rpmsg.  As per your suggestion, I check the /lib/firmware directory where I found the "dra7-ipu2-fw.xem4" but as per your suggestion file was "dra7-ipu2.fw.xem4" so there is little change in name. so this minor change is ok or still need to modify something?

Please help us to solve the issue.

Hello,

Sorry I have pressed . instead of -. 

So the firmware exist in /lib/firmaware.

The problem is when you execute ls -l /dev/rpmsg*

The output should be something like:

ls -l /dev/rpmsg*
crw------- 1 root root 242, 1 Apr 9 07:49 /dev/rpmsg-dce

 Please check these threads:

https://e2e.ti.com/support/processors/f/791/p/682075/2512742 

and your dts  file it seems like ipu2 node is missing.

Hope this helps.

Dear Margarita,

Thanks for your reply.

We did remove all the ourcustom changes from sourc code.

Our dtb file already have enable ipu2 node but we got below error.

root@am57xx-evm:~# dmesg | grep ipu

Dear Margarita,

I did remove all our changes and now I can see the device as per your list.
