Thread:Talk:R-Car/Boards/Yocto-Gen3/I2C errors appeared with multiple usb devices/reply (2)

As a result of our confirmation again, it can be reproduced, even if the USB device is not connected. Let me share the reproduction the scenario below. In addition, I used another board butI2C error is still reproduced.

[ Reproduce environment ] - Renesas bsp 3.15 - Rcar M3 StarterKit + KF-M06 - CMOS Camera OV5642 https:// www.aliexpress.com/item/OV5642-5-Million-High-Sensitivity-Camera-Module-Image-Sensor-Module-Manual-Fine-tuning-with-JPEG-Interface/32909308847.html Connected CMOS Camera to CN 29 on KF-M06. - capture command Customized based on V4L2 video capture example in here. https:// linuxtv.org/downloads/v4l-dvb-apis-new/uapi/v4l/capture.c.html please see the attached file. # capture -d /dev/video0 -F -f rgb32 -L 0 -T 0 -W 12800 -H 720 -c 1000 -t 60 -z

[pattern1] [ 1491.549362] i2c-rcar e66d8000.i2c: error -11 : f

When capture command was executed, I2C bus error occurs probability as below. pattern1: 3/10. pattern2: 4/10.

Your feedback would be welcome. Thanks
