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).
[[File:{Template:Nome-som-EVB-Console-connector.png|thumb|center|500px|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:
- connect an UART transceiver (eg: TTL-232RGVIP-WE) to J35 and to a workstation
- leave J35.3 unconnected if the transceiver is self powered
- start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,8N1
