Hi Particle Team and Community,
I am currently developing a bipedal robot named Spaz using the Particle Tachyon. Due to the active balancing and walking movements of the robot, I am experiencing significant "jello effect" and motion blur with standard rolling shutter cameras (OV5647).
I am looking to integrate the TechNexion TEVM-AR0234 camera module. This is a 2.3MP Global Shutter sensor (onsemi AR0234) that includes an onboard ISP (YUV422 output) and an onboard IMU (LSM6DSO16IS). It connects via a 22-pin MIPI CSI-2 adapter.
Technical Specs of the Module:
-
Sensor: onsemi AR0234 (Global Shutter)
-
Output Format: YUV422-UYVY (via onboard ISP)
-
Interface: 4-lane MIPI CSI-2
-
Onboard IMU: LSM6DSO16IS (accessible via I2C)
-
Connector: 70-pin standardized + 22-pin RPi Flex adapter

My Questions:
-
Has anyone successfully created a Device Tree Overlay (.dtbo) for the TechNexion TEVS driver on the QCM6490/Tachyon platform?
-
Since this module outputs YUV422 and handles ISP tasks internally, does it simplify the integration with the Qualcomm ISP pipeline, or do we still need a specific tuning file?
-
What is the recommended
target-pathfor a CCI camera node in the Tachyon overlays for Ubuntu 24.04?
I am happy to test any experimental overlays or provide logs if someone can point me toward the correct DTS structure for the Tachyon’s camera control interface (CCI).
Thanks heaps,
Marcus Gricks
