I think the low stack message may be a redherring. The error I saw was unexpected isr. It is in `imxrt_txpoll` in the Ethernet driver. @PetervdPerk-NXP - Does this ring...

Closing in favor of [1.15](https://github.com/PX4/PX4-Autopilot/pull/23110) - but 1.15 will need some commits.

@ndepal - Some background: The PX4 build supports the run time stack checking as documented http://nuttx.org/doku.php?id=wiki:howtos:run-time-stack-checking (I posted the original document) The trick is the whole system has to be...

Check the speed of the I2C it 100 kHz or 400 kHz? What voltages is connected to the Flow?

The slowest device on the line sets the rate If you have a scope or a logic analyser the best place to validate the clock is the SCL line.

@mrpollo - Would you please enumerate all the changes you unstreamed to QGC for V5X. FYI: @LorenzMeier a board_id (BOARD_TYPE in bootloader) 51 (0x33 hex) is used to select the...

This is a great move in the right direction. We are going to need a bigger ID and will have to rev the bootloader to do that. Also N.B. The...

@jfbblue0922 The should go upstream to Nuttx and com back to PX4 as a backport. Please have a look at the way the the part number [chooses the Pinning](https://github.com/PX4/NuttX/pull/304/files#diff-7b589cd0d04d9d7c39e76668e6cca5841ccae1854e6c4d304effdbbe040de283R111-R118) and...
