Preparing bootable SDcard

[CktDesigner]

I'm using the iMXRT1060-EVKB to test software, etc. in preparation for a custom board based system.   The target processor will be the iMXRT1062.

I'd like to boot from SDcard into ITCM/DTCM and have read a number of posts, etc. on how this is done.   All seem to use the EVKB board to write the SDcard.

Is there a way to use the SDcard interface built into the PC from MCUXpresso IDE to directly write a bootable SDcard?     I'd also like to use the SDcard to deliver some data for the application.    So ideally, the boot image could coexist with a FatFS on the unused part of the SDcard.    Is this possible, and if so, are there any guides on how to achieve this?

I've also seen references to NXP-MCUBootUtility as a useful tool.  But when I attempt to download/unzip it, my virus detector warns about imgutil.exe being infected with Malware...   Is there a different source for this?

Thanks!

Hi @CktDesigner ,

1.  No, you can't use MCUXpresso IDE to download code to SDcard. But MCUbootUtility can, all-in-one step.

2, Yes, download image to SD card will not destroy the FatFS in SD card normally, because it put image into the area between DBR and FAT table1. But of course, if the image is too big, it may cover the FAT table.
