VPU handtro daemon crashed in custom board using iMX8MP

trongthinh — Fri, 05 Jan 2024 04:19:33 GMT

I have a board configured as follows:
- Chip: iM8MP
- RAM: 4GB
- EMMC: 8GB.
- Audio Codec: TLV320DAC3100IRHBRYocto BSP: https://github.com/nxp-imx/imx-manifest/blob/imx-linux-mickledore/imx-6.1.36-2.1.0.xml

I have successfully brought up the Audio codec and tested it with a wave file.

$ aplay 24_48k_PerfectTest.wav

Playing WAVE '24_48k_PerfectTest.wav' : Signed 24 bit Little Endian in 3bytes, Rate 48000 Hz, Stereo

The sound comes out accurately and clearly. I continued testing using gst-play-1.0, because I wanted to play many other audio formats. I have a problem here. Take a look at the log below.

Now playing /home/root/24_48k_PerfectTest.wav Redistribute latency... Redistribute latency... 0:00:05.5 / 0:00:13.2

/usr/bin/vsidaemon crashed multiple time, and after about one minute the sound is emitted. I would like some suggestions to trouble shoot this problem? I think the correct case should be: vsidaemon doesn't crash and the sound is emitted immediately.

where do you need get audio? I tested gstreamer command as below, and can get audio from headphone,

when use gplay-1.0, get the message as below, which means gplay uses imxaudioxcvr codec, this codec isn't supported by current gstreamer, so I use another command to replace

firstly you need use aplay -l to check all of codecs current bsp support

then I used command to test by wm8960 codec as below

gst-launch-1.0 playbin uri=file:///media/24_48k_PerfectTest.wav audio-sink="alsasink device=hw:1,0"

I have found that the part number of iMX8MP in my custom board is MIMX8ML4CVNKZAB. This part number does not have VPU. So I think this is the reason of VPU hantro daemon crashed.

ok, 4 stands for i.MX 8M Plus QuadLite which doesn't have vpu and npu, since you need VPU, pls don't choose this part number
