Help!
I have been experiencing a failure like Michael Browne, but in order to not hijack his thread and add confusion I thought it best to start my own. After an initial problem connecting with the wireless and an issue entering the SSID, I initially got my board working, connected to the Husarion cloud, and ran the test (pushbutton) program successfully.
The following night I returned home to try changing the SSID to use WPA. But the CORE2 would not reach the state where the Blue and Yellow LEDs are blinking so that I can connect my phone. Also, the Husarion server cannot connect to it. I have tried hold the hcfg button during power on for up to a minute or more, but I have only red ‘pwr’ LED on solid and l2 blinking green on about a 4 second frequency. So I’m locked out for anything.
So having read Michael’s thread, I saw the instructions to see of it was possible to flash the CORE2 over serial using Visual Studio. After some fiddling around (having never used Visual Studio before), I believe this worked fine (see below), although I don’t know how to run the program.
~/husarion$ sudo kextunload -b com.apple.driver.AppleUSBFTDI
Password:
~/husarion$ ninja flash

So I resigned my self to follow more instructions and and “…Please check the voltage on this pin…” using the image posted by @Dominik2:
If hCfg is pressed, the voltage between this pin and GND is about 0V.
If hCfg is released, the voltage between this pin and GND is about 3.3V.
But my test result is not so good:
hCfg is released: 2.4 V
hCfg is pressed: 2.4 V (Failure, it would appear)
This is with a power supply 6V @ 2amp. Does the 2.4V reading suggest this is not adequate?
Can you tell me which pins to short out on hCfg to get past that? Is it just the two connection points visible on the underside of the board? Any other suggestions very much appreciated.
Also, can you confirm that the image labeled “Stable v 1.0.0” “CORE2-ROS image”
