[1] Interface requires additional configuration, such as pinmuxing. It may be possible to change the software configuration to utilize this interface even if it is not being set in the board's default configuration. Please see NXP's i.MX7D Technical Reference Manual processor technical reference manual for more information.

Supported Demos:

Demos have been adapted from the i.MX7D Sabre demos. For details on building and running demos, see PHYTEC's How-To article as well as NXP's Getting started and User's Guide for FreeRTOS_iMX7D_1.0.1 Release, located in the docs/ directory of the source code. 

Demo AppDescription
Hello Worldrun on:
  • Cortex-M4's TCM
  • QSPI
  • OCRAM
  • DDR
Blinking IMX demoUses GPT. Change blinking frequency of LED D1 on EVAL board
Low PowerDual-core power management
RPMsg

GPIO toggle (FreeRTOS) - Type command in Linux running on Cortex A7 to trigger toggling of LED D1 by FreeRTOS on Cortex M4

ping pong (Bare metal and FreeRTOS) - Transfer integer values back and forth between Cortex M4 and Cortex A7

str echo (Bare metal and FreeRTOS) - Receive and print out messages from Cortex A7

Sema4Trigger mutex lock and unlock
Driver ExamplesDescription
ADC iMX7DPrints ADC output every second for ADC1_IN3
FlexCANLoopback and network modes
GPIOPress button S1 to switch LED D1 on/off

GPT

Interrupt based polling of counter for two GPT instances
I2C(Interrupt and polling) Write data to EEPROM on SOM, connected to I2C1 address 0x50. Read data back to check that data matches.
UART(Interrupt and polling options) board will receive and echo characters typed from keyboard. Uses interface UART2
WDOGWDOG3 timer demo with ISR refreshing timer

Development Tools

Can be compiled with the following:

  • Makefile support with GCC ARM embedded toolchain (Tested with revision 5.4-2016-q2)
