3.1.2.1 Booting of TIDA-050043

Insert the SD card into the SD card slot provided in the board and set the boot switches to boot from SD card. If executables are not found in the configured boot source, then the software is automatically fetched from the SD card.

Connect micro-B side of a USB cable to debug port of the board and Type-A side to a host PC. The connections on the board at this step will look like Figure 31.

Use TeraTerm or Putty to open a Terminal and get the debug log from the device node if the host PC is running Windows. Change port number according to the COMxx port found in Device Manager for the FTDI chip.

For example, when I am testing this board I can select the COM7 port with a baud rate of 115200 and leave the other Putty settings as the default option.

If the debug prints are coming when the board is powered on, then that interface is working. When prompted to logon, enter ‘root’ and press the Enter key.

There are many other Linux functions and commands that are useful for testing the power supplies and consumption of TIDA-050043, and the next section provides some examples.
