I tried several USB cables. Different USB-ports and different computers.
I connected to the board successfully in the past. I even flew with it before. Thats the strange thing. I switched the receiver and now I can’t connect anymore. After removing the receiver it still does not work. I tried to connect via an external FTDI adapter. No luck, but maybe I did something else wrong with the FTDI adapter.
The LEDs blink in a particular pattern. I’ll let you know about the pattern as soon as I am at home 😉
@freakazoid that’s just what my STM32 experienced friend suggested when I told him about it. I also don’t quite understand what the triflight_0_6_RC1_RCEXPLORERF3.hex from here : https://github.com/lkaino/Triflight/releases is about, wether or not that is actually for the V4 idk.
Did you ever figure this out? I had this happen to me on one FC. The flashing indicates that the processor can’t detect the gyro. It will not initiate a USB connection until it can communicate with the gyro so it keeps looping looking for a gyro response. In my case I replaced the gyro chip and then it worked fine.
