Red LED and Hot IC's on Navio2

(Pierre-Emmanuel Lépicier) #22

Hi Andrew,

Any idea of what is the problem?
I need to know if the board is broken and if I need to buy one again, because my project is on standby…

Hi @pelepicier,

Can I ask you do the following steps once more:

  • double-check the board connection
  • format SD and reinstall image
  • ssh your Navio2
  • do sudo apt-get update && sudo apt-get dist-upgrade
  • do sudo emlidtool ardupilot
  • choose vehicle, version and board
  • do sudo nano /etc/default/arducopter
  • set your parameters
  • do sudo systemctl daemon-reload
  • do sudo systemctl start arducopter

Also, can you clarify if these steps work with your second RPi?

As for the chip, which one?

Hi Andrew,

I already have done these points twice, always the same problem.
The chip is the ARM X STM32F103.

@pelepicier, can you try to do sudo emlidtool rcio update -f?

I tried connecting with QgroundControl : same problem than before, no answer of the device, LED green when starting and turns off after 3 sec.
