#✅ - Alisha Mk XI not recognized

So I've had the crashworks Alisha MK XI since August last year and it was working great straight out of the box. I had accidentally reset the board and was trying to set the code back on it and I keep getting the same message,

avrdude: ser_open(): can't set com-state for "\.COM4" Failed uploading: uploading error: exit status 1

I've tried both USB ports on my computer
Uninstalled and reinstalled both drivers
Reset Arduino IDE and my computer

I've tried using another nano board I have and it works fine, so I don't know if it's a hardware or software issue. Since the other one I used works I'm guessing it's hardware but I'm not sure what to do.

Are you plugging into the USB port on the MK-XI board (Top left corner) -or- plugging into the USB port on the Nano attached to the board ?

Also , make sure nothing is connected to the MK-XI when uploading code, disconnect the Servos and LEDs

Does the nano come off the Alisha board, could I try it that way?

tardy beacon

Sure, you can carefully remove it, it is in a socket

#

Also try setting the Arduino IDE to use the "Old Bootloader"

And no other applications are running in the background. I tried the other nano I have to see if it uploads anything and it still works. Just not the one that came with the Alisha

Ok after I took the faceplate off my helmet the motors still work even though I had accidentally hit the reset button a couple of times, one of the arms came loose on my test helmet.but I was originally trying to adjust the opening angle because it opens way to much for the helmet I'm trying to fix up.

Can you copy and paste the full output from the IDE here?

Yes.

Some of these questions/things to try may be redundant to what you've already tried but...

  • Double check that it is the correct com port
  • Inspect the Arduino Nano itself, make sure there's no visible damage to the USB port or other components
  • Double check that there are no other applications running that are consuming the com ports like Cura
  • I'm not a Windows user but the error could be something in your Windows OS preventing access to this particular Arduino Nano device
  • Try a different com port
  • Try uninstalling and re-installing your CH340 drivers

(It's possible the other Nano that does work is using FTDI drivers instead)

  • Send us a pic of the Nano giving you trouble, we may be able to identify which Nano it is and provide further steps or notice something wrong with it.

I don't know if it's visible but it looks like the board is slightly splitting I don't know if it's the cause. But it's still works with the code that's already on there.

The one that came with the Alisha is on the bottom. The one on top is the one that works

#

The one that works has the ch340 on the chip itself

#

But not the one that doesn't work. I don't know if it was rubbed off or something

I'm also getting a new error message as well

Have you tried the different booloader options? (new vs. old?)

hallow kraken
#

I was about to give up thinking that I had no other solutions left, and I had a board that would only work in a specific helmet.

#

Again thank you so much

#

One more thing where can I change the opening angle amount for the faceplate in the code, I can't see it anywhere. I'm sure I'm just blind and passing over it. It's the reason I'm going through all this
