Note:

To support i.MX 8M Plus, the patch for IAR and Segger J-Link should be installed. The patch named iar_segger_support_patch_imx8mp.zip can be used with MCUXpresso SDK. See the readme.txt in the patch for additional information about patch installation.
For the security reason, only after the U-Boot is boot up, the JTAG can be allowed to connect to M core.
