NON XIP via JTAG RT1176

[AnteoJ]

According to this application note: https://www.nxp.com/docs/en/application-note/AN14069.pdf , NON XIP images can only be loaded via MCU Boot Utility via UART and USB. 

I was looking to confirm that there is no way to load an XIP Image to flash via MCU Link or Jlink within MCUXpresso IDE? 

If MCU Link must be used, I'd like to confirm these are the correct UART pins bellow to route out. I do not see an option for Boot through USB on the datasheet: https://www.nxp.com/docs/en/data-sheet/IMXRT1170AEC.pdf (apologies if I missed it). I've seen a few things online mentioning boot via USB is just connecting USB to the same UART Pins?

Thanks,

Anteo

Hi @AnteoJ ,

Thanks for your interest in NXP MIMXRT series!

Non-XIP images such as those booted from SD card need to be flashed with MCUBootUtility or NXP's official MCUXpresso Secure Provisioning tool.

If the image is XIP, it can be programmed to flash by debugger such as JLink/DAP. It's easy to do in MCUXpressoIDE or any other IDE.

If you are using RT1170-EVK/EVKB, you will find that there is an MCU-Link on the board, which is an on-board debugger, which is convenient for customers to flash programs and debug directly through the on-board debugger without using an external debugger. Moreover, MCU-Link can be changed to JLink or CMSIS-DAP debugger by programming different firmware.

For details, you can check EVK/EVKB hardware schematics.

Best regards,
Gavin
