Can it be used with Arduino Pico 5.10?

[ebiyans]

I am using eOS on Pico2 with ArduinoIDE.
After compiling with Arduino-Pico 5.10, it stopped working.
It seems like OSC communication over USB (SLIP) isn't working.

It worked with 5.00.
Is there a way to get it to work with 5.10?

Hi, I work on PlatformIO with bo problems using 5.10 and Pico2.
Can you compile it? Did you close the Arduino IDE after uploading?

Compilation is complete.
Arduino IDE is closed after uploading.

From the EOS log,
it seems like the "OK" reply after ”ETCOSC?" is not working properly.

Are you using macOS or WIN?

If your code have following lines comment them out and try again

// This is a hack around an Arduino bug. It was taken from the OSC library examples
#ifdef BOARD_HAS_USB_SERIAL
#ifndef TEENSYDUINO
while (!SerialUSB);
#endif
#else
while (!Serial);
#endif

I am using WIN
I commented it out but the situation was the same

The EOS daignostics shows the following:
//EOS v3.3 (ETCnomad) daignostics
OSC USB Deveice Handshake Initiated [ETCOSC?]
COM Port[1] Write failed with result 8, error 0x1

The problem rarely occurs and happens when things changes too fast.
After uploading for the IDE to Pico, close the IDE and then replug the Pico.
Now you can start EOS, you can also replug your Pico while EOS is running.
I added an USB test sketch, the delay() after SlipSerial.begin() should not needed, it is optional.
I tested with WIN11 and macOS and it works.

After uploading, I closed the IDE and restarted the power, but it still didn't work (Arduino Pico 5.1).
It works fine with Arduino Pico 5.0.

Board:
W5100S-EVB-Pico2, W6100-EVB-Pico2, WaveShare RP2350-Plus, RasPi-Pico

The USB test sketch was helpful, thank you.

Sorry that I can't help you, for me it works. Maybe you can make an issue on https://github.com/earlephilhower/arduino-pico
