Auto-Focus (AF) feature of AR1335 IAS camera module not working #9

I have successfully ran the app in petalinux on Kria KV260 Vision AI Starter Kit but the AR1335 module does not seem to focus dynamically on the objects and its focus remain static. I have gone through the datasheet of the camera module and found that the AF feature is managed by the Voice Coil Motor (VCM) module. The power to the VCM module is provided by the 34th pin of the IAS0 connector on the KV260 carrier card. Upon looking at the schematic of the carrier card, it was found (to the best of my knowledge) that the 34th pin is only connected to the test-point pin (TP28) on the carrier card and can't be accessed by Kria K26 SOM. The pin requires around 2.8V +- 0.1V in order to power-up the VCM module. Are we suppose to provide power to the test-point TP28 externally or is there a way to power it internally?

We acknowledge that limitation on the KV260 Starter Kit and while we would love to support auto focus, we have nothing to announce at this point. We will keep the community informed of any potential news on this front. Currently, auto focus can only be enabled by developing a custom carrier card for K26 or K24 SOM. Please reach out to kv260_apps@amd.com if there are any more questions.

Thanks. Can we connect the IAS_2V75 (TP23) point on the KV260 carrier card (of 2.75V) to TP28 to power the VCM module externally to check whether the AF feature of the sensor module is working or not?
