Bootloader gives error about serial port already being open. Linux and Windows

Development Boards Artemis
1

I’ve tried to upload an example sketch to my board under Windows through the Arduino IDE and Linux through arduino-cli. I’m using v 1.0.11 of the board support package. I get the following errors:

Windows:

Sketch uses 7392 bytes (0%) of program storage space. Maximum is 960000 bytes.


Artemis SVL Bootloader
COM1 is currently open. Please close any other terminal programs that may be using COM1 and try again.

Linux:

> arduino-cli -v upload --fqbn SparkFun:apollo3:amap3nano --port /dev/ttyUSB0 ./libraries/Examples/examples/Example8_BLE_LED


Artemis SVL Bootloader

phase:  setup
        cleared startup blip

phase:  bootload
/dev/ttyUSB0 is currently open. Please close any other terminal programs that may be using /dev/ttyUSB0 and try again.

Am I missing something?

User error on the windows side. I had the wrong COM port selected. Linux issues still remains.

Try this.

It turned out that I was seeing a combination of arduino-cli not copying the .bin file and artemis_svl giving confusing error messages. artemis_svl already had the port open when it did the phase: setup. Due to some unfortunate error handling logic, it was giving the serial error message when it was failing to open the .bin. I sent a PR (https://github.com/sparkfun/Arduino_Apollo3/pull/67) to clear up the the error messages and hacked my local arduino-cli to give me the bin file.
