mecc_single_error#
Overview#
The MECC project is a simple demonstration program of the SDK MECC driver. It uses single error injection in the on-chip ram and then access the OCRAM 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:
MECC single error example.
Original ocram data correct.
Single error injection success.
Original ocram data correct.
Single error information success.
Single error address: 0x20240020.
Single error ecc code: 0xc9.
Single error low 32 bits data: 0x44332215.
Single error high 32 bits data: 0x11223344.
