i.MXRT116x

The NXP i.MXRT116x devices are dual core MCUs with an ARM Cortex-M7 and Cortex-M4 core.

QSPI support

The RT116x 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.

Signal = Pin	Loader name	Supported since software version
