The NXP i.MXRT1170 devices are dual core MCUs with an ARM Cortex-M7 and Cortex-M4 core.

QSPI support

The RT117x does not come with internal flash but with external flash connected to the FlexSPI bus, only. The external FlexSPI controller allows to connect several different flash types like QSPI, HyperFlash and Octaflash. Furthermore, the external flash can be connected to different pin / ports of the FlexSPI controller which makes a auto-detection very difficult thus an out-of-the-box solution which works for all setups is kind of impossible. For that reason, the J-Link software supports the evaluation board setup, only. Other setups may work but without any warranty or guarantee from SEGGER. If you are working with a different setup and looking for support for this setup, please get in touch with SEGGER.

Supported FlexSPI1 pin configurations

QSPI flash programming requires special handling compared to internal flash. For more information about this, please see the QSPI Flash Programming Support article.
J-Link supports multiple pin configurations for FlexSPI1. For details on how to select a specific flash loader, please see here.

FLEXSPI_SS0 = GPIO_SD_B2_06
FLEXSPI_SCLK = GPIO_SD_B2_07
FLEXSPI_DATA0 = GPIO_SD_B2_08

Supported FlexSPI2 pin configurations

QSPI flash programming requires special handling compared to internal flash. For more information about this, please see the QSPI Flash Programming Support article.
J-Link supports one pin configuration for FlexSPI2.

FLEXSPI_SS0 = GPIO_SD_B1_00
FLEXSPI_SCLK = GPIO_SD_B1_01
FLEXSPI_DATA0 = GPIO_SD_B1_02

Reset

Rev B0 or later silicon:
When the RT1170 rev B is reset via debugger (SYSRESET_REQ), the boot ROM will not jump to the flash application although it is valid but enter a debug loop at a fixed PC address (0x00223104). The debugger then needs to initialize PC and SP manually in order to jump to the user application.
