hello 756948396,
there’re functions to handle rtcpu messages, which is the firmware you could find in the rce-fw partition (camera-rtcpu-rce.img).
you might refer to [Xavier Series (SoC) Technical Reference Manual] and check the [Multimedia Complex]-> [Camera Subsystem]-> [Real-Time Camera Engine (RCE)] for details.
suggest you should debug your sensor drivers and sensor device tree,
could you please check from kernel side to see if there’s suspicious failures.
please also refer to Sensor Driver Programming Guide and review your drivers.
in addition, please follow below steps to enable VI tracing logs to gather more details from rtcpu side.
enable VI tracing logs.
