A-star 32u4 board not showing up on the board selection

Hi,

I am trying to program my romi with arduino and it was working fine before but when I tried to connect it again, the arduino suddenly stopped recognizing the romi board. The wire (micro USB to USB) works fine and the com port is working. I feel that it has something to do with the romi 32u4 board (maybe it got fried). Is it possible to check if the romi 32u4 board is still working or somehow get this board to connect?

Thanks

Now the romi update firmware is grayed out??? Everything was working fine a few hours ago, but now nothing is working.

Hello.

Could you try following the instructions in the “Reviving an unresponsive Romi 32U4” section of the user’s guide? There are a few different methods described there, and they all should work (but some have some caveats), so if you’re having trouble with one you can try another.

Also, could you clarify where you are seeing the “update firmware” text?

I just revived it, but when I try to upload code with arduino, the com disconnects immediately

I then get an error that says

Connecting to programmer: .
Found programmer: Id = “CATERIN”; type = S
Software Version = 1.0; No Hardware Version given.
Programmer supports auto addr increment.
Programmer supports buffered memory access with buffersize=128 bytes.

Programmer supports the following devices:
Device code: 0x44

Could you tell me what is going on with this? Thanks

It is normal for the board to reset when getting programmed, and nothing in that output looks abnormal or is indicating an error; are you sure the board is not getting programmed successfully? Could you try enabling verbose output during both compiling and uploading in the File > Preferences options, and post the full output you get when you try programming it again?
