VAR-SOM-MX25 Windows Boot Debug Port
Serial debug messages are used by the boot loader and OS images to report status and error information. In addition, the boot loader uses serial input to allow user interaction.
1 Desktop Workstation Serial Debug Port
Any terminal emulation application can be used to display messages sent from the serial port of the target. Configure the terminal application with the following communications parameters:
- Bits per second: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: none
2 Target Serial Debug Port
The VAR-SOM-MX25 BSP has been configured by default to use internal UART1 routed to the P2 10-pin header for serial debug communication. Connect an enclosed flat cable to the header such that signed wire of the cable will be aligned to pin 1 of the header; the 9-pin female connector of the cable should be connected to the serial port of desktop workstation.
