As technology advances, more and more commercial and industrial applications are utilizing embedded microcontrollers and Digital Signal Processors (DSPs) for control purposes. However, utilizing these components requires careful consideration of the hardware and software configuration. Evaluation boards, such as the AM335x-SOM-EVB, are employed to provide the necessary tools to evaluate and test embedded microcontrollers and DSPs. This article will discuss the applications and working principles of the AM335x-SOM-EVB, an evaluation board specifically designed for AM335x Sitara processors.

AM335x-SOM-EVB is a single board computer based on the Sitara AM335x processor from Texas Instruments. The board is designed to be suitable for evaluation and verification applications that involve data acquisition, industrial control, and data communication. The evaluation board provides all the necessary components such as memory, GPIO, and data communication peripherals. It also supports JTAG debugging and can be connected to a PC or an embedded development kit with USB or Ethernet interfaces.

The Sitara processor used in the AM335x-SOM-EVB features an ARM Cortex-A8 core clocked at up to 600 MHz. It has 64 KB of instruction and 64 KB of data cache which provides a combined 128 KB of on-chip memory. The processor includes six integrated peripherals which include MMC, SPI, I2C, UART, SDIO, and USB 2.0. The evaluation board also features two DDR2 SODIMM memory sockets, an on-board ethernet MAC with PHY and two SATA connectors.

The evaluation board enables developers to rapidly prototype their applications with minimal external components. It has an on-board memory of 2 GB DRAM and 4 GB NAND Flash. Additional memory can be added with two 128 MB DRAM and two 8 MB NAND Flash memory extensions. The GPIO header enables connection of the evaluation board to other peripherals such as sensors, LCD displays, and input devices.

The processor used in the AM335x-SOM-EVB can be operated in either standalone mode or connected to a debugger. The board includes two additional debugging interfaces, JTAG and UART. The board is also capable of running software in the on-board NAND Flash or external NOR Flash or Serial Data Flash. The board has two USB ports which can be used to connect the board to a PC for development, testing and programming.

The AM335x-SOM-EVB evaluation board is an ideal platform for prototyping and debugging applications. It provides all the necessary components for the evaluation and testing of embedded microcontrollers and DSPs. It is easy to set up and operate, and provides a wide range of features and capabilities. This makes it a great choice for applications where quick turnaround and rapid prototyping are critical.
