Uploading error. Port not recognized?

Development Tools IDE 2.x
1

Hi, I am a super newbie so please be patient with me!
I have Arduino ELEG UNO R3 and I downloaded IDE 2.3.4. My computer is Apple M1 Max with Sonoma 14.5. What I want to do is to load Firmata. I choose Arduino Uno under Arduino AVR Boards but under Port I only see Bluetooth-Incoming but I am guessing that I am supposed to see something like COM5? I tried to load it by selecting Bluetooth-incoming and I keep getting the error as below.

fork/exec /Users/MBP15/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++: no such file or directory

Compilation error: fork/exec /Users/MBP15/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++: no such file or directory

I am really really lost... I went to Privacy & Security and changed it to allow accesories to connect to Always, but it doesn't work. Please advise. Thank you soooo much in advcance!

Have you connected a USB cable from your computer to the UNO?

You should change the title of your post, it has nothing to do with libraries, it's a simple upload error.

That seems to indicate a corrupt installation of the AVR board package. You can try to downgrade the AVR board package to version 1.8.3 using board manager in the IDE, test and next upgrade the board package again to version 1.8.6.

FYI, this is not an upload error.

@sonofcy, OP never mentioned libraries. It some Mac term :slight_smile:

Um, the title of the post is "Library uploading error. Wrong port?'
I do agree though in hindsight, this may not be your standard upload problem, it may well be an incomplete or incorrect install. Do we know that he chose the right architecture for instance, there are two Macs, x86 and ARM. His is an M1 therefore ARM

Yes, I installed arm64.

Omg, it worked!! I uninstall the 1.8.6 and downgraded to 1.8.3. I am using MadMapper and Firmata an now it's working. Thank you so much!!

Hi @curious3000. You actually have two separate and unrelated problems:

Board doesn't produce a port

Spurious compilation failure

I see you have already solved the "spurious compilation failure" problem. Are you still experiencing the problem of the "ELEG UNO R3" board not producing a port?

COM5 is a Windows port name. On macOS, the port will probably be named something like /dev/cu.usbmodem211410 or /dev/cu.usbserial-211410. The port named /dev/cu.Bluetooth-Incoming-Port is definitely not the port of the "ELEG UNO R3" board.
