Issue template

Hardware description: Teensy 4.0 with PlatformIO
Version or commit hash: galactic

Steps to reproduce the issue

Create an empty project in platformIO with the configuration suggested in the README for Teensy 4.0 in patformio.ini:

[env:teensy40]
platform = teensy
board = teensy40
framework = arduino

lib_deps =
    https://github.com/micro-ROS/micro_ros_arduino

build_flags =
    -L ./.pio/libdeps/teensy40/micro_ros_arduino/src/imxrt1062/fpv5-d16-hard
    -l microros
    -D ARDUINO_TEENSY41

And a simple main program importing microros:

#include <Arduino.h>
#include <micro_ros_arduino.h>

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

Expected behavior

Successfull Compilation

Actual behavior

Following error appears:

.pio/build/teensy40/libFrameworkArduino.a(startup.c.o): In function `configure_external_ram':
startup.c:(.flashmem+0x4a0): undefined reference to `_extram_end'
startup.c:(.flashmem+0x4a4): undefined reference to `_extram_start'
collect2: error: ld returned 1 exit status
*** [.pio/build/teensy40/firmware.elf] Error 1

Without the build flag -D ARDUINO_TEENSY41, PlatformIO throws errors from the NativeEthernet library:

/home/user/.platformio/packages/framework-arduinoteensy/libraries/NativeEthernet/src/NativeEthernet.cpp: In static member function 'static int EthernetClass::begin(uint8_t*, long unsigned int, long unsigned int)':

Additional information

We were previously using an older precompiled version in galactic with PlatformIO without any problems. It compiles without errors using Arduino IDE. We also tried with a Teensy 3.2 with the same behaviour.

Thanks!

you can ignore NativeEthernet library. Here's a reference: https://github.com/linorobot/linorobot2_hardware/blob/master/firmware/platformio.ini#L59-L66

Thanks @grassjelly! It works as you suggest. Closing the issue.
