The stand-alone configuration can be used for most software development use cases which do not require the controlSOM to interface to other hardware. An XDS110 debug-probe (XDS110ISO-EVM) is required for this configuration. Power is provided to the controlSOM through XDS110 debug-probe. The XDS110 debug-probe is sold separately.

In this configuration, Code Composer Studio™ Theia connects to the controlSOM via JTAG and enables software development. The XDS110 debug-probe also enumerates a virtual COM port (VCP) for communication with the MCU via UART.

Follow these steps to enable this configuration:

1. Collect the required equipment:
   1. F29H85x controlSOM (F29H85X-SOM-EVM)
   2. XDS110 isolated debug probe (XDS110ISO-EVM)
   3. USB Type-C® cable
2. Verify the switch settings are correct on each EVM.
   1. F29H85X-SOM-EVM:
      1. Use S1 to select the desired boot mode.
      2. Use S3/S4 to select the desired ADC voltage reference mode.
   2. XDS110ISO-EVM: No switch configuration is necessary.
3. Connect the XDS110ISO-EVM to connector J1 of the controlSOM.
4. Connect the USB cable into connector J5 on the XDS110 isolated debug probe. The XDS110 isolated probe and the controlSOM are powered on.
5. Verify the power status LEDs (LED1 and LED2) on the controlSOM are turned on.
6. The controlSOM is ready for use. Follow the steps in Software to get started developing software.

Figure 2-1 Stand-alone Configuration

In the stand-alone configuration, the 12-pin prototype header (J2) on the XDS110ISO-EVM provides access a few ADC and GPIO pins on the F29H85x device. Table 2-1 lists the ADC and GPIO pins which can be accessed on this prototype header.
