Console interface[edit | edit source]

Description[edit | edit source]

The Console interface is available on the Evaluation Kit at the connector J35.

J35 is a 4 pin (4x1x2.54mm) header connector for the two-wires UART2 port, used for debug purposes (bootloader and operating system serial console).


Console connector

Signals[edit | edit source]

The following table describes the interface signals:

Pin# SOM Pin# Pin name Pin function Pin Notes
1 J15.250 UART2_TXD Transmit line
2 J15.248 UART2_RXD Receive line 10K pull-up to 3V3_CB
3 - 3V3_CB Power output for transceiver supply BOARD_PGOOD driven rail
4 - DGND Ground

Device mapping[edit | edit source]

UART2 is mapped to /dev/ttymxc1 device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.

Device usage[edit | edit source]

To connect to the debug serial port:

  1. connect an UART transceiver (eg: TTL-232RGVIP-WE) to J35 and to a workstation
    • leave J35.3 unconnected if the transceiver is self powered
  2. start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,8N1
