panic: runtime error when running the CLI daemon on my Pi #820
Description
Bug Report
Current behavior
I am trying to use the Arduino CLI daemon on armv7l over gRPC. I had this error in the Pro IDE:
daemon INFO panic: runtime error: invalid memory address or nil pointer dereference

Disabling the telemetry did help:
cat ~/.arduinoProIDE/arduino-cli.yaml
board_manager:
additional_urls: []
daemon:
port: "50051"
directories:
data: /home/pi/.arduino15
downloads: /home/pi/.arduino15/staging
user: /home/pi/Arduino
logging:
file: ""
format: text
level: info
telemetry:
addr: :9090
enabled: false
Expected behavior
Environment
- CLI version (output of
arduino-cli version):arduino-cli Version: 0.11.0 Commit: 0296f4d - OS and platform:
Linux raspberrypi 4.19.118-v7l+ #1311 SMP Mon Apr 27 14:26:42 BST 2020 armv7l GNU/Linux
Additional context
I used the https://downloads.arduino.cc/arduino-cli/arduino-cli_0.11.0_Linux_ARMv7.tar.gz URL to get the CLI.
Update: I have corrected my original description; disabling the telemetry helped to work around the problem. I can confirm, without the telemetry, the daemon runs on ARM.
