Hey all, I am using a IMX678 and using a synchronized camera setup with L4T 35.4.1 and Jetpack 5.1.2 this is the error I am seeing anyone seen this before? also seeing this in dmesg: [ 449.798291] bwmgr API not supported [ 450.004057] imx678 7-0036: imx678_adjust_hmax_register: HMAX: 550 [ …

The frame rate control in sensor kernel driver actually. Thanks

Hello @josh244 , How is it going ? That is interesting, we have never seen that error before. However, doing some research we found in this post that according to NVIDIA that message should not be concerning, the actually error causing your camera system to fail might be somewhere else. Now, plea…

@proventusnova Thanks for your feedback! We are using a custom carrier board and have configured a working device tree and overlay for the our proprietary board Our manufacturer created the driver based on the source files from the camera vendor We did have to modify the device tree to enable the…

Dump the device tree to confirm the setting. sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

Attached! also result from command (converted to txt file for sharing here): extracted_proc.txt (426.1 KB)

Does slave address 0x36/0x37 working while launch both of them? Maybe have another camera connect to another bus to try.

yes you can see both are bound in dmesg logs: [ 7.532845] imx678 7-0037: probing v4l2 sensor [ 7.537566] imx678 7-0037: initializing mipi... [ 7.542260] imx678 7-0037: xmaster-gpio not found [ 7.548917] imx678 7-0037: tegracam sensor driver:imx678_v2.0.6 [ 7.601774] imx678 7-0037: im…

Could you verify by below command. v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=200 -d /dev/video0& v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=200 -d /dev/video1

Can increase the frame rate? And can open two cameras simultaenuously? v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=200 -d /dev/video0& v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=200 -d /dev/video1&
