I created two projects, and want to work simultaneously on them (Split screen code & split terminals).
I was able to upload the code to both boards using the following commands, but it stopped working after a couple of uploads.
pio run -t upload -e slave
and
pio run -t upload -e master
My paltformio.ini files look like this:
[env:master]
platform = teensy
board = teensy35
framework = arduino
build_flags = -D TEENSY_OPT_FASTER
upload_protocol = teensy-cli
upload_port = COM17
monitor_port = COM17
monitor_speed = 115200
and
[env:slave]
platform = teensy
board = teensy35
framework = arduino
build_flags = -D TEENSY_OPT_FASTER
upload_protocol = teensy-cli
upload_port = COM16
monitor_port = COM16
monitor_speed = 115200
I also tried uploading using the following command:
pio run -t upload --upload-port COM16 -e slave
But it fails as below. (Unable to access COM17, which is not the port I want to upload to!)
PS C:\Users\x\Documents\PlatformIO\Projects\timesync_slave> pio run -t upload -e slave -v

(hint: press the reset button)
Note that despite having upload port set to COM16 in both my ini file and command line argument, it tries to upload to COM17, which is not the port I’m trying to upload to. What am I missing?
Thanks!
