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 a 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 QSPI setup
- J-Link Software: >= V6.64
- Hardware: NXP MIMXRT1170-EVK
- Flash: IS25WP128-JBLE (QSPI flash) connected to FlexSPI port A

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.
