  • EVK-MIMXRT595 board

  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J40) on the board

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Launch the debugger in your IDE to begin running the demo.

Running the demo

The log below shows example output of the frequency measure demo in the terminal window:

Capture source: External clock (clk_in) (main system clock reference), reference frequency = 198000000 Hz
Computed frequency value = 23999410 Hz
Expected frequency value = 24000000 Hz

Capture source: LPOSC clock (main system clock reference), reference frequency = 198000000 Hz
Computed frequency value = 813468 Hz
Expected frequency value = 1000000 Hz

Capture source: FRO192M clock (main system clock reference), reference frequency = 198000000 Hz
Computed frequency value = 152082435 Hz
Expected frequency value = 192000000 Hz
