Getting Battery Voltage Displayed in QGC

QGroundControl
1

Pixhawk 6X Pro and PM02d high voltage version plugged into Power 1 on a Holybro Jetson baseboard.

PX4 firmware version 1.15.4
QGC version v4.4.4

I’ve ensured:

  • SENS_EN_INA228 = 1
  • SENS_EN_INA226 = 0
  • BAT1_SOURCE = 0 (Power Module)
  • BAT2_SOURCE = -1 (Disabled)

But in the battery widget on Fly page, I’m seeing:

In Mavlink console, typing dmesg, I get these relevant lines:

INFO [ina228] Failed to init INA228 on bus 1, but will try again periodically.
ina228 #0 on I2C bus 1 (external) address 0x45
INFO [ina228] Failed to init INA228 on bus 2, but will try again periodically.
ina228 #1 on I2C bus 2 (external) address 0x45

I’ve been on this for hours. Can anyone shed any light? Expert advice would be hugely appreciated!
