$ cd ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1
$ chmod 755 portenta_post_install.sh
$ sudo ./portenta_post_install.sh

This will create the file /etc/udev/rules.d/49-portenta_h7.rules as follows:

# Portenta H7 bootloader mode UDEV rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="035b", GROUP="plugdev", MODE="0666"

Supposing the ArduinoCore-mbed core version is 3.4.1. Now only one file must be copied into the directory:

• ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1/portenta_post_install.sh

Whenever a new version is installed, remember to copy this files into the new version directory. For example, new version is x.yy.zz

This file must be copied into the directory:

• ~/.arduino15/packages/arduino/hardware/mbed_portenta/x.yy.zz/portenta_post_install.sh

10. For RTL8720DN boards using AmebaD core

To avoid compile error relating to PROGMEM, you have to copy the file Realtek AmebaD core pgmspace.h into Realtek AmebaD directory (~/.arduino15/packages/realtek/hardware/AmebaD/3.1.4/cores/ambd/avr/pgmspace.h).

Supposing the Realtek AmebaD core version is 3.1.4. This file must be copied into the directory:

• ~/.arduino15/packages/realtek/hardware/AmebaD/3.1.4/cores/ambd/avr/pgmspace.h

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied into the directory:

• ~/.arduino15/packages/realtek/hardware/AmebaD/x.yy.zz/cores/ambd/avr/pgmspace.h

11. For SAMD21 and SAMD51 boards using ArduinoCore-fab-sam core

To avoid compile error relating to SAMD21/SAMD51, you have to copy the file ArduinoCore-fab-sam core pgmspace.h into ArduinoCore-fab-sam samd directory (~/.arduino15/packages/Fab_SAM_Arduino/hardware/samd/1.9.0/boards.txt).

Supposing the ArduinoCore-fab-sam samd core version is 1.9.0. This file must be copied into the directory:

• ~/.arduino15/packages/Fab_SAM_Arduino/hardware/samd/1.9.0/boards.txt

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied into the directory:

• ~/.arduino15/packages/Fab_SAM_Arduino/hardware/samd/x.yy.zz/boards.txt

12. For Seeeduino RP2040 boards

To be able to compile, run and automatically detect and display BOARD_NAME on Seeeduino RP2040 (XIAO RP2040, Wio RP2040 Mini) boards, you have to copy the whole Seeeduino RP2040 Packages_Patches directory into Seeeduino samd directory (~/.arduino15/packages/Seeeduino/hardware/rp2040/2.7.2).

Supposing the Seeeduino RP2040 core version is 2.7.2. These files must be copied into the directory:

• ~/.arduino15/packages/Seeeduino/hardware/rp2040/2.7.2/boards.txt
• ~/.arduino15/packages/Seeeduino/hardware/rp2040/2.7.2/variants/Seeed_XIAO_RP2040/pins_arduino.h

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz These files must be copied into the directory:

• ~/.arduino15/packages/Seeeduino/hardware/samd/x.yy.zz/boards.txt
• ~/.arduino15/packages/Seeeduino/hardware/samd/x.yy.zz/variants/Seeed_XIAO_RP2040/pins_arduino.h
