Good day. I have committed to using these nice little boards for my LED applications. However I have been having issues uploading my sketches reliably.
One moment I upload and it gives me the Java error dump, I click upload again, and it goes into an infinite port seeking. Then I click upload about 1 to 20 times more with the Java or infinite port seeking until it gives up and actually finds the correct port and uploads.
I find unplugging the USB cable and plugging it back in makes the success rate a little bit faster. But this has really slowed down my prototyping speed.
Here is a section of the successful upload:
Forcing reset using 1200bps open/close on port COM37
PORTS {COM1, COM37, } / {COM1, COM38, } => {COM38, }
Found upload port: COM38
The odd thing here is in the drop down menu, it only shows me port 37, but then finds the next incremental port and successfully uploads. When it goes into the infinite port seeking error, it just looks for 37. I wonder if there is a way I can force it to choose the next port up?
Here it is when it fails:
Forcing reset using 1200bps open/close on port COM37
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}

PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}
PORTS {COM1, COM37, } / {COM1, COM37, } => {}

And here is the Java error:

I am using Arduino IDE 1.8.16
Latest board as of this writing.
I tried plugging into different USB ports on my pc, ensuring the controller is getting enough voltage. Because I use LEDs there are times it may drop the voltage too low.
I have ready thru the forums here and some people have had issues, but really there doesn’t seem to be a clear fix for this issue. Is this just an inherent flaw that we have to live with? Or is there some special thing I gotta do to make this reliable? Maybe not use the Arduino IDE?
