There are two version of the i.MX RT1170 Evaluation Kit:
- MIMXRT1170-EVK (no longer available for purchase)
- MIMXRT1170-EVKB
The key differences between the two versions of are laid out in the MIMXRT1170-EVKB Board Hardware User Guide:
One important change is the QuadSPI flash used on each board. This means that if you attempt to use SDK projects created for the RT1170-EVKB, it will not run properly on an older RT1170-EVK board due to using the mismatched QSPI configuration data. And new releases of MCUXpresso SDK only support the newer EVKB board.
However there is a simple fix to get those newer i.MX RT1170 EVKB MCUXpresso SDK projects to run on the older i.MX RT1170 EVK hardware. Simply download the MCUXpresso SDK 2.16.00 for the original RT1170-EVK board, unzip the archive file, and then copy the evkmimxrt1170_flexspi_nor_config.h and evkmimxrt1170_flexspi_nor_config.c files found in \SDK_2_16_000_MIMXRT1170-EVK\boards\evkmimxrt1170\xip into your EVKB project's xip folder.
Then either delete/rename the EVKB version of the evkbmimxrt1170_flexspi_nor_config.c and evkbmimxrt1170_flexspi_nor_config.h files from the project to avoid compiler conflicts. This will update the QSPI configuration for that project to be compatible with the QSPI hardware on the original EVK.
As an exmaple, here is the RT1170 Hello World project with that change - the EVKB files were renamed with a .orig extension so they would not be included in the compilation:
Note that due to the new hardware features found on the EVKB board there are some EVKB SDK projects that simply can't be supported on the original EVK board. But this work-around will provide support for many MCUXpresso SDK projects that don't require those new EVKB board features.
