4.2.2 MCU Firmware

The easiest way to boot the Sitara MCU is to prepare an SD card containing the bootloader (tiboot3.bin) and an application (app). Use the bootloader, which is part of the Sitara SDK. For the application, the SDK provides examples used in this reference design. The interface through the PHI connector can be tested by using the PRU_IO example, interfacing an ADS127L11 through this interface and showing the samples. For more information and how to get started, refer to the SDK. documentation.

To test the Ethernet circuit of the design, use this example from the SDK with only slight modification to support the DP83TD510E Ethernet PHY.
