EMEM Decode Error on Camera Streaming (L4T 36.4.0)

Hi Nvidia,

We have ported our custom camera driver from L4T 35.5.0 to 36.4.0 on the AGX Orin 64GB Devkit… Following the porting process, we have observed continuous EMEM address decode errors in the kernel logs (dmesg) when streaming video using GStreamer or guvcview. Despite these errors, the camera stream functions correctly without any visible issues. Notably, this issue was not present in L4T 35.5.0.

GStreamer command used:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080,pixelformat=UYVY ! Fpsdisplaysink

Error log snippet:

[ 7031.839310] tegra30_mc_handle_irq: 1787 callbacks suppressed

[ 7031.839324] tegra-mc 2c00000.memory-controller: vifalw: write @0x0000007ffc280000: EMEM address decode error (EMEM decode error)

We would appreciate your support in diagnosing and resolving this issue. Please let us know if additional logs or details are required.

Thanks.

I referred to the link below, which mentions updating to 36.4 L4T, but I am currently working on this.

The EMEM Decode Error during camera streaming on L4T 36.4.0 could be related to memory allocation or driver issues. Double-checking your system settings or updating drivers might help resolve the problem.

Are you referring to the camera driver or another driver? Also, which system settings are you referring to

hello akash.kumar2,

let’s try below to convert the format as I420 for fpsdisplaysink.
for instance, $ gst-launch-1.0 -v nvv4l2camerasrc device=/dev/video0 ! 'video/x-raw(memory:NVMM), width=1920, height=1080, format=UYVY' ! videorate ! nvvidconv ! 'video/x-raw(memory:NVMM), format=I420' ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0
