Implement the same initial clock configuration as what imxrt1176 has. Make an own table for PLL and root clock configurations for m33 and m7 targets. For the PLLs the code still only supports configuring the ARM_PLL. The difference to imxrt1176 is, that instead of just boolean .enable field, this table uses an .action field with 3 states: CONFIGURE, DISABLE and IGNORE. The reason is, that some root clocks can't be just forcefully stopped, but need a root-clock-specific sequence. This is solved by just leaving these clocks marked as IGNORE, so they retain their current state. Specifically, disabling the SEMC and NETC roots by M33 will prevent the M7 from booting. Also FLEXSPI shouldn't be touched, if the code is being executed from there. Also add a function for enabling 24 MHz oscillator clock, and an extendable function to enable the clock sources based on the clock configuration table.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
