- Page 1 User's Guide SPRUII2 – November 2017 AM437x IDK Evaluation Hardware This document describes the hardware architecture of the AM437x industrial development kit (IDK), part number TMDSIDK437x, which is based on the AM437x processor from TI. Contents ........................Introduction ....................Functional Block Description .......................
- Page 2 The EVM is equipped with a AM437x processor, from TI, and a defined set of features, to allow the user to experience industrial communication solutions using serial or Ethernet-based interfaces. Using standard interfaces, the IDK can interface to other processors or systems, and act as a communication gateway in this case.
- Page 3 Figure 2. AM437x Industrial EVM Block Diagram Processor The AM437x processor is the central processor for this EVM. All the resources on the board surround the AM437x processor to provide development capabilities for hardware and software. See the AM437x data sheet and TRM for details about the processor.
- Page 4 Reset Signals SYS_RESETn is a reset signal running to several peripherals and the AM437x which performs a reset on those peripherals. SYS_WARMRESETn is asserted by the push button and used to force a reset of the AM437x and the other peripherals. The AM437x can also pulldown on the RESET_INOUTn signal to cause the SYS_RESETn line to go active.
- Page 5 1. MMC0 2. USB_MS (USB1) 3. USB_CL (USB0) 4. QSPI See the GP EVM schematic for more details. See the AM437x TRM and data sheet for the definitions of each of the sysboot signals. 2.5.2 C Address Assignments In the AM437X Industrial EVM, each separate board has an I C ID memory that contains the details of the identity of that board such as its configuration.
- Page 6 SPI NOR Flash The Industrial EVM supports a 512-Kbit (128K × 4) SPI flash memory from Macronix (MX66L51235FMI- 10G) in a 16SOIC package. The SPI port of the AM437X device is used to interface with the flash. 2.7.3 Board Identity Memory Each board contains a 256KB serial EEPROM which contains board specific data that allows the processor to automatically detect which board is connected and the version of that board.
- Page 7 2.12 Camera The camera Interface from the AM437x processor is terminated on the 12 × 2 header, J5. The camera interface is supported using the J5 (AXK7L24223G) connector provided. The custom made Camera Module, from TI, shall be interfaced with this header.
- Page 8 Functional Interface Mapping Some signals of the AM437x device are connected to a fixed device on the EVM that cannot be changed. Some of the signals of the AM437x device, however, are connected to devices on the EVM based on the profile setting.
