|

## Enable the rt feature of [`rp-pac`](https://docs.rs/crates/rp-pac). This brings in the [`cortex-m-rt`](https://docs.rs/cortex-m-rt) crate, which adds startup code and minimal runtime initialization.
|
|
rt = [ "rp-pac/rt" ]
|
|
|

## Enable [defmt support](https://docs.rs/defmt) and enables `defmt` debug-log messages and formatting in embassy drivers.

|
|
## Reexport the PAC for the currently enabled chip at `embassy_rp::pac`.
|
|
## This is unstable because semver-minor (non-breaking) releases of `embassy-rp` may major-bump (breaking) the PAC version.
|
|
## If this is an issue for you, you're encouraged to directly depend on a fixed version of the PAC.
|
|
## There are no plans to make this stable.

## Enable the timer for use with `embassy-time` with a 1MHz tick rate.

## Enable ROM function cache. This will store the address of a ROM function when first used, improving performance of subsequent calls.
|
|
rom-func-cache = []
|
|
## Enable implementations of some compiler intrinsics using functions in the rp2040 Mask ROM.
|
|
## These should be as fast or faster than the implementations in compiler-builtins. They also save code space and reduce memory contention.
|
|
## Compiler intrinsics are used automatically, you do not need to change your code to get performance improvements from this feature.
|
|
intrinsics = []
|
|
## Enable intrinsics based on extra ROM functions added in the v2 version of the rp2040 Mask ROM.
|
|
## This version added a lot more floating point operations - many f64 functions and a few f32 functions were added in ROM v2.
|
|
rom-v2-intrinsics = []
|
|
|
|
## Allow using QSPI pins as GPIO pins. This is mostly not what you want (because your flash is attached via QSPI pins)
|
|
## and adds code and memory overhead when this feature is enabled.
|
|
qspi-as-gpio = []
|
|
|
|
## Indicate code is running from RAM.
|
|
## Set this if all code is in RAM, and the cores never access memory-mapped flash memory through XIP.
|

## This allows the flash driver to not force pausing execution on both cores when doing flash operations.

#! ### boot2 flash chip support
|
|
#! RP2040's internal bootloader is only able to run code from the first 256 bytes of flash.
|
|
#! A 2nd stage bootloader (boot2) is required to run larger programs from external flash.
|
|
#! Select from existing boot2 implementations via the following features. If none are selected,
|
|
#! boot2-w25q080 will be used (w25q080 is the flash chip used on the pico).
|
|
#! Each implementation uses flash commands and timings specific to a QSPI flash chip family for better performance.
|

## Use boot2 with support for Renesas/Dialog AT25SF128a SPI flash.

## Use boot2 with support for Gigadevice GD25Q64C SPI flash.

## Use boot2 that only uses generic flash commands - these are supported by all SPI flash, but are slower.

|
|
## Use boot2 with support for ISSI IS25LP080 SPI flash.
|

|
## Use boot2 that copies the entire program to RAM before booting. This uses generic flash commands to perform the copy.

## Use boot2 with support for Winbond W25Q080 SPI flash.
