[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 App | Description |
|---|---|
| Hello World | run on:
|
| Blinking IMX demo | Uses GPT. Change blinking frequency of LED D1 on EVAL board |
| Low Power | Dual-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 | |
| Sema4 | Trigger mutex lock and unlock |
| Driver Examples | Description |
|---|---|
| ADC iMX7D | Prints ADC output every second for ADC1_IN3 |
| FlexCAN | Loopback and network modes |
| GPIO | Press 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. |
