arduino:dfu-util@0.9.0-arduino2 not available for arm64

[arpit6232]

Bug Report

Unable to install arduino:mbed core on arm64 arch.

Current behavior

Arduino BLE 33 sense was connected to NVIDIA Jetson Nano.

./arduino-cli core install arduino:mbed

Installs perfectly on x86. But leads to a failure on Arm64 devices.

Expected behavior

To perfectly install areduino:mbed@1.3.2.

It is expected to perfectly install all the libraries for the core.

Environment

Host: Jetson Environment : Linux jetson-nano-qspi-sd 4.9.140-l4t-r32.4+g166b394331e2 SMP PREEMPT aarch64 GNU/Linux

• CLI version (output of arduino-cli version): arduino-cli alpha Version:0.18.0 Commit: 46c23166
• OS and platform: aarch64 GNU/Linux

You can see there is no build for the aarch64-linux-gnu host type of your Jetson, so getting this error from Arduino CLI is normal and expected.

I see you have already reported the lack of ARM Linux 64 bit support on the arduino/ArduinoCore-mbed issue tracker: arduino/ArduinoCore-mbed#176
