      Hi @SKA
      Apologies no one responded promptly.
      From what I gather, these are best to be sent back as an RMA and we can try to recover them.

      D1 (green) is an indication of the local 3.3V power being Good. So, that implies you have 3.8V input, and the 3.3V reg is OK.
      DS2 (RGB) is controlled by Qty-3 GPIOs from the SoC. This can briefly blink on boot until the GPIOs are configured by apps software.
      D2 (green) is the 5V USB VBUS USB1 (10-pin) port power indicator, which only comes ON after the QRB5165 boots and Apps controls the GPIO to turn the VBUS ON.

      On failed SW loads, it is common to diagnose that by seeing DS2 or D2 blink, which indicates boot loops. D1 should NEVER go off, if so, something is wrong in HW or cabling.

      We do caution any customer that sets up their own CI or internal validation automation to include a nice pause before repeated power cycles. A common 5 second rule is good to let the large caps discharge, or certain ICs will never fully reset. This is the most common cause of "bricking" devices.

      The RMA is your best bet here and we can try to recover them for you, or diagnose for any other issues: https://www.modalai.com/pages/rma

      Hi @SKA
      Alex's instincts are correct, we do not have a smaller plug in board for just tracking in a synce'd config. We only had an M0155 for one image sensor for a while, so your best bet is what Alex said and get the new M0188 for VOXL 2 Mini (VOXL 2 uses M0173, whereas VOXL 2 Mini uses M0188)
      It's quite cost competitive for what it does!!

      DFS undistort issue

      @SKA , this is most likely due to the max disparity value being too large - for 1280x800 resolution the maximum value is 32.

      the max disparity parameter limit is as follows:

      width <= 640 : max disparity = 64 (or less, in steps of 4) 640 < width <= 1280 : max disparity 32 (or less in steps of 4) 1280 < width <= 1920: 16, 12,8, or 4

      So in your case, you should update your max disparity parameter to 32 or less.

      I have been testing AR0144 DFS recently and i also found that i needed to increase the min_threshold and cost_threshold from the default of 10 that was used for OV7251. I found that values in the range of 50-80 produced good results.

      Here is some additional information regarding DFS:

      min_threshold:
      Lower bound for adjusting occlusion cost threshold.
      When set to < cost_threshold, the occlusion penalty
      is varied linearly from this minimum value from the first row
      to the last row.
      The last row takes cost_threshold.
      Range: 0 to 100
      Recommended range: 50 to 75
      min_threshold <= cost_threshold

      cost_threshold:
      Occlusion cost threshold.
      The higher the value, more smoothness is enforced.
      Range: 0 to 100
      Recommended range: 50 to 75

      @SKA What pipes do you see listed in /run/mpa? If you run the command voxl-inspect-vio does it show that VIO is running okay?

      @SKA Yes, VFT is actually deprecated in 1.4.1

      Please replace your ovins config with this and give it a try:
