We’ve been experiencing some unusual behavior with ZED X camera not loading sometimes (less than 1 in 10, quite rare). Usually resolved by reboot, however, that led us to inspect the logs and noticed the following:
ar0234issues:zedx_probe: ar0234 initialization failed
i2c clientissue:[ 13.408025] i2c i2c-13: Failed to register i2c client eeprom_zedx at 0x54 (-16)
How can we fix these?
We are running Jetpack 6.0 (L4T 36.3.0), latest Quad link drivers (stereolabs-zedlink-quad_1.2.1-SL-MAX96712-all-L4T36.3.0_arm64.deb) and 4.2 ZED SDK
