Reset button and pin stopped working

[ardyouino]

Hi,

Just when I didn't want it to happen the reset button AND the the reset pin don't work either. This was working fine until last night. I took the entire board out of the project, checked nothing was short circuiting, and it still no result.

With the Nano IoT 33 BLE can anyone suggest the best procedure for dealing with this. The only reference I can find to similar symptoms is from 2014 with a deleted follow up post by 'System'

After some further investigation, it turns out that it is partly working but not fully:

1. It interrupts code in progress
2. When a hardware switch is used if it is closed and reset pin is grounded it compiles but then says "No device found" until it is uploaded without being grounded.

So somehow the symptoms are:

1. When the reset pin or the button is used it is doing half a reset
2. It doesn't show as disconnected in the IDE at the bottom as it used to do but when it comes to uploading it is.

Perhaps if anyone can recommend a way to re-flash, do a hard reset on this board that might work. I can see this procedure:

1. Unplug USB from the Arduino.
2. Press and hold the reset button.
3. Plug in USB and power up.
4. Continue holding and upload the sketch. Once it's done uploading, release the reset button.

But it doesn't work for me.

Thanks for your help.

I fixed the problem by reinstalling the IDE. It was a problem with the software on the computer not a problem with the board. After when HW button is pressed or when either reset pin is grounded it moves in the bottom left of the screen to say [not connected] as it did before.

These things are sent to try us, its like the old pull the plug out, switch everything off and hey, it works haha.
