Lib.rs

Generates a suitable default flash control block and boot stub for linking into applications intended to run on the MIMXRT595-EVK, which is the official evaluation kit for the NXP i.MX RT500 series of microcontrollers.

With the bootstub feature enabled (which is on by default), linking this crate into your application will use the bootstub_builtin and [fcb] macros from crate mimxrt500-bootstub to produce symbols that will be placed in the appropriate locations by the linker script provided by the mimxrt595-evk crate. The flash control block uses the values provided by mimxrt595-evk, in [FCB].

To use this, declare a dependency on this crate and then ensure it will be linked into your program by declaring it as an extern crate:

extern crate mimxrt595_evk_bootstub as _;

Your application must also use cortex-m-rt and a suitable build script to arrange for using its linker script link.x when building your application. That will include the memory.x linker script provided by mimxrt595-evk, which will arrange for the boot stub code and flash control block to be placed where the on-chip boot ROM expects to find them.

This library exports no symbols itself. It exists only to add some special static variables to your program. It's a separate crate so that applications with different needs can still depend on mimxrt595-evk but generate their own boot stub and flash control block, perhaps using the macros provided in crate mimxrt500-bootstub.
