Where can I get the most up-to-date firmware for the VOXL2 IO breakout board? The board we recently bought still seems to have outdated firmware on it, and it isn't working with an updated VOXL2. The VOXL2 is running voxl-suite version 1.5.0. When I run voxl-px4 in daemon mode (voxl-px4 -d) I'm seeing error messages about an invalid firmware version from voxl2_io (see attached)

I tried updating to the firmware available on the public downloads page mentioned in the documentation and get a similar error

I've managed get things to work using the firmware here: https://forum.modalai.com/topic/2446/connecting-i2c-device-on-voxl2/20, however the post seems to imply that it's a test firmware. Where else would I be able to obtain the current VOXL2 IO board firmware? Or should I carry on using the firmware from the post?

@Andrew-Jue , you can find the latest firmware for the IO board in `/usr/share/modalai/voxl2-io-tools/firmware/modalai_m0065_firmware_v0_2_RC1_f94baad1.bin` on your VOXL2 or on gitlab: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl2-io/-/tree/master/voxl2-io-tools/firmware

You can update the firmware using our `voxl-esc` tools, as documented here : https://docs.modalai.com/voxl2-io-firmware/#how-to-update-firmware

This version of the firmware is the latest and has been stable for over one year.
