Device Logs
There are a few different ways to connect to a device:
- Accessing text logs and ePackets over RTT/Serial/PyOCD using
infuse gateway. - Accessing the text logs over Bluetooth using
infuse bt_log.
This method uses infuse gateway to receive text logs and command gateways over serial links.
This method can be used to only receive text logs by using the -d flag (while will display data only).
Text logs and ePacket data are exchanged over the
epacket_serial device in devicetree. Refer to hardware
configuration of the firmware to determine which peripheral to use if there are multiple present.- Note the name of the microcontroller you are connecting to. e.g. for the nRF52840 -
nRF52840_xxAA. - Connect your JLink programmer
- To connect to an
nRF52840_xxAAboard run:
infuse gateway --rtt nRF52840_xxAA
or replace with your board name as required.
- Connect your device to your computer via serial/usb
- Note the name of the serial port your device is connected to.
- To connect to
/dev/ttyACM0run:
infuse gateway --serial /dev/ttyACM0
or replace with your serial port as required.
Attaching and detaching the device will cause the serial device to appear and disappear.
Checking which ports are present in Device Manager (Windows) or
ls /dev/tty* for macOS/Linux
can be a good way to identify which port to use if there are multiple options.If multiple ports appear at the same time, it's typically the one with the smaller value.- Note the name of the microcontroller you are connecting to e.g.
stm32l451ceux - Connect your programmer
- To connect to a
stm32l451ceuxboard run:
infuse gateway --pyocd stm32l451ceux
or replace with your board name as required.
You should now be connected to the board, wait for data to appear in the terminal.
This cannot be used to run gateway commands, and can only be used to view text logs.
- Note the Infuse-ID of your device.
- Run the command:
infuse bt_log --id 0x1234567890ABCDEF
