TDA4VL-Q1: can't get stream from imx390

Part Number: TDA4VL-Q1

Tool/software:

Hi TI teams,

We can't get video stream out while using imx390 D3CM cameras in TDA4VL EVB+vision board with Linux SDK 8.6. Due to our application, we didn't use RTOS SDK, just use LINUX SDK.

We follow https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j721s2/09_00_00_08/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Camera/CSI2RX.html.

Add following lines to tisdk_j721s2-evm_defconfig

CONFIG_I2C_ATR=y

CONFIG_VIDEO_CADENCE_CSI2RX=y

CONFIG_VIDEO_TI_J21E_CSI2RX=y

CONFIG_PHY_CADENCE_DPHY=y

Add following lines to uEnv.txt

name_overlays=k3-j721s2-fpdlink-cpb-fusion.dtbo k3-j721e-fpdlink-imx390-cm-0-0.dtbo k3-j721e-fpdlink-imx390-cm-0-1.dtbo k3-j721e-fpdlink-imx390-cm-0-2.dtbo k3-j721e-fpdlink-imx390-cm-0-3.dtbo

But got error while running v4l2 command:

root@j721s2-evm:~# v4l2-ctl -d2 --set-fmt-video=width=1936,height=1100,pixelformat=RG12 --stream-mmap
[ 116.183505] ds90ub960 5-0036: Failed to get source frame desc for port 0
VIDIOC_STREAMON returned -1 (Broken pipe)

All messages was saved to this log file:

tda4vl_imx390_test.log

How to solve it? Thanks!

Jeff

Hi Jeff,

I am currently out of office on business travel. Please expect a ~1-2 day delay in my response.

Thank you,

Hi Jeff,

Which imx390 module are you using? The rugged camera module should use "rcm" rather than "cm" in the device tree overlay name: k3-j721e-fpdlink-imx390-rcm-0-0.dtbo.

Thank you,

Fabiana

Hi Jaimes,

We use imx390 D3CM cameras, not imx390 D3RCM cameras. When we use 4 x k3-j721e-fpdlink-imx390-rcm-0-X.dtbo, it got error while booting, look like i2c slave addr isn't correct.

BR,

Jeff

Hello,

Make the change to the format across the media entities in your media-ctl pipeline using the media-ctl tool to match that of the sensor (fmt:SRGGB12_1X12/1936x1100). After verifying that you have changed all the relevant entities by running media-ctl -p once more, try running a GStreamer pipeline similar to the one below to stream from imx390 to a connected display.

gst-launch-1.0 v4l2src device=/dev/video10 io-mode=dmabuf-import ! \
video/x-bayer, width=1936, height=1100, framerate=30/1, format=rggb12 ! queue leaky=2 ! \
tiovxisp sink_0::device=/dev/v4l-subdev10 sensor-name=SENSOR_SONY_IMX390_UB953_D3 \
dcc-isp-file=/opt/imaging/imx390/linear/dcc_viss.bin sink_0::dcc-2a-file=/opt/imaging/imx390/linear/dcc_2a.bin \
format-msb=11 ! tiovxldc dcc-file=/opt/imaging/imx390/linear/dcc_ldc.bin sensor-name=SENSOR_SONY_IMX390_UB953_D3 \

Hi Fabiana,

We reference this ticket: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1173511/faq-tda4vm-steps-for-executing-linux-csi-on-sdk/4416478?tisearch=e2e-sitesearch&keymatch=media-ctl%2525252520AND%2525252520SRGGB12#4416478, and we can capture /dev/video8 image by initializing it:

media-ctl -V '"ds90ub953 5-0044":0 [fmt:SRGGB12_1X12/1936x1100 field: none]'

media-ctl -R '"ds90ub960 5-003d" [0/0 -> 4/0 [1]]'

media-ctl -V '"ds90ub960 5-003d":0 [fmt:SRGGB12_1X12/1936x1100 field: none]'

media-ctl -R '"4500000.ticsi2rx" [0/0 -> 1/0 [1]]'

But we can't capture from other 3 cameras. Like /dev/video9:

media-ctl -V '"ds90ub953 5-0045":0 [fmt:SRGGB12_1X12/1936x1100 field: none]'

media-ctl -R '"ds90ub960 5-003d" [1/0 -> 4/1 [1]]'

media-ctl -V '"ds90ub960 5-003d":1 [fmt:SRGGB12_1X12/1936x1100 field: none]'

media-ctl -R '"4500000.ticsi2rx" [0/1 -> 2/0 [1]]'

Could you tell us how to setup for other 3 cameras?

BR,

Jeff

Hi Jeff,

I recommend a running a script to set up all connected cameras at once with ease. Take a look at the script linked below and let me know if you have any questions.

https://github.com/TexasInstruments/edgeai-gst-apps/blob/main/scripts/setup_cameras.sh

Thank you,

Fabiana

Hi Fabiana,

After running setup_cameras.sh, it shows:

IMX390 Camera 0 detected
device = /dev/video-imx390-cam0
name = imx390
format = [fmt:SRGGB12_1X12/1936x1100 field: none]
subdev_id = /dev/v4l-imx390-subdev0
isp_required = yes
ldc_required = yes
IMX390 Camera 1 detected
device = /dev/video-imx390-cam1
name = imx390
format = [fmt:SRGGB12_1X12/1936x1100 field: none]
subdev_id = /dev/v4l-imx390-subdev1
isp_required = yes
ldc_required = yes
IMX390 Camera 2 detected
device = /dev/video-imx390-cam2
name = imx390
format = [fmt:SRGGB12_1X12/1936x1100 field: none]
subdev_id = /dev/v4l-imx390-subdev2
isp_required = yes
ldc_required = yes
IMX390 Camera 3 detected
device = /dev/video-imx390-cam3
name = imx390
format = [fmt:SRGGB12_1X12/1936x1100 field: none]
subdev_id = /dev/v4l-imx390-subdev3
isp_required = yes
ldc_required = yes
VIDIOC_SUBDEV_S_ROUTING failed: -25
Unable to setup routes: Inappropriate ioctl for device (25)

It shows error when it try to set routes for "cdns_csi2rx.4504000.csi-bridge".

I try this command, but it still report same error:

media-ctl -R '"cdns_csi2rx.4504000.csi-bridge" [0/0 -> 1/0 [1]]'

It seems that I can't modify routes for "cdns_csi2rx.4504000.csi-bridge", so only /dev/video8 can get stream by default setting, other 3 cameras can't.

Does cdns_csi2rx not support VIDIOC_SUBDEV_S_ROUTING in TDA4VL 8.6 Linux SDK?

How to fix it? Thanks.

BR,

Jeff

Hi Jeff,

Apologies for the delay in response. Could you try running this older version of setup_cameras.sh and let me know if it gives you the same message?

https://github.com/TexasInstruments/edgeai-gst-apps/blob/70a07bfead5e8ec6f6a4007d6164248912abb556/scripts/setup_cameras.sh
