  • USB Type-C cable

  • MCIMX93-EVK board

  • JLink Plus

  • 12V~20V power supply

  • Personal Computer

Board settings

No special is needed.

Prepare the Demo

  1. Connect 12V~20V power supply and JLink Plus to the board, switch SW301 to power on the board

  2. Connect a USB Type-C cable between the host PC and the J1401 USB port on the target board.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Boot Linux BSP to u-boot, and load M core image from SD card to run. (Put the image into SD card before.) => load mmc 1:1 0x80000000 /sdk20-app.bin => cp.b 0x80000000 0x201e0000 0x20000 => bootaux 0x1ffe0000 0
