Overview
The sdramc example shows how to use SEMC controller driver to initialize the external SDRAM chip.
SDK version
- Version: 2.15.000
Toolchain supported
- IAR embedded Workbench 9.40.1
- Keil MDK 5.38.1
- GCC ARM Embedded 12.2
- MCUXpresso 11.8.0
Hardware requirements
- Mini/micro USB cable
- EVKB-IMXRT1050 board
- Personal Computer
Board settings
No special settings are required.
Prepare the Demo
- Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
- Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
When the demo runs successfully, the log would be seen on the OpenSDA terminal like:
