The MYD-C437X-V2-PRU Development Board is a complete
evaluation platform especially designed for users to take full advantages of the Programmable
Real-time Unit (PRU) as well as the 3D graphics acceleration features from Texas
Instruments (TI) Sitara AM437x ARM
Cortex-A9 processors. It can support -40 to +85 Celsius extended temperature operation and is ideal for industrial
communications, industrial control, and industrial drives applications.
The MYD-C437X-V2-PRU development board employs the MYC-C437X-V2 SOM as
the core controller board which is mounted onto the MYD-C437X-PRU base board
through two 0.8mm pitch 2*100-pin board-to-board connectors. The CPU Module has
the core components AM4377 processor, 512MB DDR3, 4GB eMMC flash, 32KB EEPROM,
Ethernet PHY and PMIC integrated on board. The base board has additionally extended
a rich set of peripherals through headers and connectors from the SOM and some extended controller chips including three serial ports, one USB Host ports, one Mini USB Device port, one Gigabit
Ethernet, two 10/100Mbps Ethernet ports from the PRU-ICSS subsystems, one CAN,
one RS485, one Camera interface, one Micro SD, LCD, Touch screen and more
others.
MYD-C437X-V2-PRU Development Board
The AM437x processor family consists of 4 pin-pin compatible devices (AM4376, AM4377, AM4378 and AM4379) with various
options including speed grades, packages, graphics and peripherals. MYIR delivers
the MYD-C437X-V2-PRU board with TI AM4377 processor by default which is able to
support EtherCAT through two PRU-ICSS Ethernet ports and run TI SYS/BIOS v6.45
Real-time Operating System.
AM437x Device
The MYD-C437X-V2-PRU board comes with necessary cable
accessories and a product disk containing the Linux 4.1.18 and TI RTOS (SYS/BIOS 6.45) software packages and detailed
documents. The complete platform provides a quick AM437x starter kit for users
when getting the goods out-of-the-box right away.
