Serial monitor 'No monitor available for port protocol serial` #2100

Closed m410 closed 1 year ago

m410 commented 1 year ago

Describe the problem

I'm not able to use the serial monitor with arduino-pico. I've only tried using 'raspberry pi pico w'. Scripts build and flash the device as expected but the serial monitor never attaches.

Error from commandline:

To reproduce

Follow these install instructions: https://github.com/earlephilhower/arduino-pico#installation I've tried library versions 3.2.2 & 3.2.1.

I used this basic blink sketch, but others show the same behavior. This same sketch works for me on IDE 1.8.19.

#include "Adafruit_TinyUSB.h"
#include "hardware/pio.h"

void setup() {
  Serial.begin(115200);

  while (!Serial);
  delay(100); 

  Serial.println("Startup");
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  Serial.println("Looping...");
  digitalWrite(LED_BUILTIN, HIGH); 
  delay(1000);   
  digitalWrite(LED_BUILTIN, LOW); 
  delay(1000); 
}

Expected behavior

Serial monitor should work.

Arduino IDE version

2.1 & 2.1.1-nightly

Operating system

macOS

Operating system version

Ventura 13.4

No monitor available for the port protocol serial

Thanks for reporting it to us. Interesting one. Please check what IDE2 logs when you plug/unplug the 'raspberry pi pico w' board.

You can start IDE2 by adjusting the log level to debug. On my macOS, it looks like this:

/Applications/Arduino\ IDE\ 2.1.0.app/Contents/MacOS/Arduino\ IDE --log-level debug

When IDE2 has started, please clean the terminal, and plug/unplug the board. IDE2 will log things. Please share everything, but I am looking for such events in particular. These are the events when I plugin in the RP2040 board:

2023-06-16T13:15:40.306Z discovery-log INFO {"eventType":"add","port":{"matchingBoardsList":[{"name":"Arduino Nano RP2040 Connect","fqbn":"arduino:mbed_nano:nanorp2040connect","isHidden":false}],"port":{"address":"/dev/cu.usbmodem14301","label":"/dev/cu.usbmodem14301","protocol":"serial","protocolLabel":"Serial Port (USB)","propertiesMap":[["pid","0x005E"],["serialNumber","FFFFFFFFFFFFFFFF"],["vid","0x2341"]],"hardwareId":"FFFFFFFFFFFFFFFF"}},"error":""}

Or the Board config changed: is also very interesting in this case:

2023-06-16T13:15:40.317Z root DEBUG Board config changed:  {"selectedBoard":{"name":"Arduino Nano RP2040 Connect","fqbn":"arduino:mbed_nano:nanorp2040connect","port":{"address":"/dev/cu.usbmodem14301","addressLabel":"/dev/cu.usbmodem14301","protocol":"serial","protocolLabel":"Serial Port (USB)","properties":{"pid":"0x005E","serialNumber":"FFFFFFFFFFFFFFFF","vid":"0x2341"},"hardwareId":"FFFFFFFFFFFFFFFF"}},"selectedPort":{"address":"/dev/cu.usbmodem14301","addressLabel":"/dev/cu.usbmodem14301","protocol":"serial","protocolLabel":"Serial Port (USB)","properties":{"pid":"0x005E","serialNumber":"FFFFFFFFFFFFFFFF","vid":"0x2341"},"hardwareId":"FFFFFFFFFFFFFFFF"}}

Thank you for helping!

(Normally, I would have asked you to attach the log files, but messages with debug level are missing from the log 🤦)

Update:

but messages with debug level are missing from the log

Hi! I’m away from my computer, I’ll rerunnwirh debug on by Monday morning EST

m410 commented 1 year ago

Here's the output arduino-ide-debug.txt

Update: I initially had the pico connected when I started Arduino IDE. disconnected then reconnected it.

Thanks for the logs, @m410.

I have received some internal assistance, and the problem seems to be in the platform.txt of the core. All discoveries and monitors must be specified in the platform.txt. Something like this:

# Required discoveries and monitors
# ---------------------------------
pluggable_discovery.required.0=builtin:serial-discovery
pluggable_discovery.required.1=builtin:mdns-discovery
pluggable_monitor.required.serial=builtin:serial-monitor

Here are a few PRs as an example of how people ported a legacy platform to the newer pluggable discovery and monitor:

If you wonder why the same sketch works in IDE 1.x but not in 2.x, well, I had the same question, and maintainers of the core logic explained to me that this is expected.

Since the necessary changes have to be performed in the core, I decided to close this IDE2 issue.

You know where to make the changes if you are the core maintainer. If you are a user of the core, please request a change on their GitHub page, or ask around on the Arduino forum: https://forum.arduino.cc/c/software/ide-2-x/93.
