flexspi_xecc_single_error#
Overview#
The XECC project is a simple demonstration program of the SDK XECC driver. It uses single error injection in the external memory and then access the external memory to demo single error interrupt.
Supported Boards#
MIMXRT1170-EVKB
Hardware requirements
Mini/micro USB cable
MIMXRT1170-EVKB 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
The log below shows the output of the hello world demo in the terminal window:
XECC single error example started!

Correcdted read data: 0xddccbbaa
Uncorrecdted read data: 0xddccbbae
Single error address: 0x3000a000
Single error read data: 0xddccbbae
Single error ECC code: 0x22cc44aa
Single error bit postion: 0x4

XECC single error example successfully.
Note: this example need to burn XECC_ENABLE(840[3]) in fuse to enable XECC module, which is disabled by default.
