The board is in office so I could do it on next Monday.
I meant that I did reflash the firmware without updating, and my I lost connection from NAVIO with MP after conecting for a while. The LED light became solid yellow or no light.
And I also tested reflash firmware with update, still lost connection.
My project has stuck with the lost connection issue for already 2 months.
To make my deadline, I have to work against the clock.
I think that I applied myself to cooperating with you of testing, and I cannot waste time on it anymore …
Therefore, if you could not find the problem of the NAVIO2 board through internet could you
just replace a new one for me and test it by yourselves?
It may also save time for you…
It takes so long because this doesn’t look like a hardware issue. It’s rather strange and unexpected behavior. However, all tests you accomplished for now make me think that this is not software related.
The only assumption I have for now is that STM on Navio2 was burned. It might occur when you connected ESCs to servo rail wrongly:
Let’s try to check it. Could you please verify if the STM chip is getting hotter when the ardupilot fails?
