Linux

Device not found​

Meadow on Linux will typically appear as a serial device /dev/ttyACM* unless it's in BOOT mode.

There a couple of "gotcha's" which you should be aware of and may vary depending on your Linux distribution:

  1. You may not have user permission to access the serial device
  2. Port probing may be active (aka ModemManager) - this is the system trying to detect what you have plugged in and will block access

To overcome these issues, add new rules to udev.

Create a file:

/etc/udev/rules.d/99-wilderness-labs.rules

# Wilderness Labs
ATTRS{idVendor}=="2e6a", ENV{ID_MM_DEVICE_IGNORE}="1", ENV{MTP_NO_PROBE}="1", MODE:="0666"


# 0483:df11 - STM32F4 Discovery in DFU mode (CN5)
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE:="0666"

Reload udevd rules with

sudo udevadm control --reload
