Always write the path as "abosolute" (relative to the root of pico-sdk) as that makes searching for it (when building the RP2040 datasheet) much faster. This matches the behaviour of extract_build_defines.py and extract_cmake_configs.py
* Small whitespace fixup
* typo bugfix
* Small refactoring of check_board_header.py
* Make structure of rp2040_interface_pins.json more explicit, so that it can be more easily extended
* Move definition of valid-pins from python to json
* Check that each interface includes all (minimally) expected pins
Note that UART_CTS, UART_RTS & SPI_CSN are classed as optional
* Split "expected_functions" into "required" (all of these pins must be present) and "one_of" (at least one of these pins must be present)
Without this change, using cyw43 has a dependency on printf code for printing
error message. Everywhere else in cyw43-code this dependency is masked with the
CYW43_PRINTF-macro. This PR extends the usage of the CYW43-PRINTF macro to the
SPI-support code.
* Fix PICO_DEOPTIMIZED_DEBUG not updating compiler flags
Setting CMAKE_${LANG}_FLAGS_DEBUG_INIT specifically only sets the flags for the Debug config the first time it is configured by CMake, pulling the initially-configured flags from CMakeCache.txt on subsequent configurations. This causes PICO_DEOPTIMIZED_DEBUG to not have any effect after the initial configuration, causing breakpoint issues when debugging certain functions.
Clearing the cache of the debug flags allows the flags to be updated every configuration, and appended to appropriately (such as with "-g").
See Issue #1618 and the comments of Pull Request #1620 for further details.
Fixes#1618
To make stdio logging quicker it's probably a good idea to set the default
uart speed 921600, but it's only configurable by adding this define to
your project. Make it configurable from the cmake command line.

with this change we can use PICO_SDK_FETCH_GIT_TAG to specify a release tag for the Pico SDK to download.
example usage:
```
set(PICO_SDK_FETCH_FROM_GIT true)
set(PICO_SDK_FETCH_FROM_GIT_TAG "1.5.1")
include(pico_sdk_import.cmake)
```
* Build boot_stage2 with Bazel
Introduces the initial foundations of a Bazel build, including a
toolchain, critical generated headers, platform patterns, and enough
BUILD files to build boot_stage2.
* Bazel libraries to support picotool
* Move SDK defines to toolchain
* Switch to `archive_override` in MODULE.bazel
Uses archive_override where applicable to allow transitive bzlmod deps
to propagate.
* Multiplatform objcopy selection in Bazel build
Makes an objcopy alias that redirects to the objcopy tool for the
current exec platform, which allows boot_stage2 to build on Linux,
macOS, and Windows.
* Generate Bazel build files
Adds initial set of generated Bazel build files. Note that these do not
yet build, as dependency cycles are present.
* Fix dependency cycles in Bazel build
Fixes many dependency cycles, some were unintentionally created by the
build file generator, others are true dependency cycles that require
manual workarounds.
* Silence warning in pico_stdio Bazel build
Silences a stray warning in the Bazel build.
* Fix wildcard Bazel build
This makes `bazel build //...` succeed, and also prevents the fetching
of toolchains that aren't compatible with the current execution
environment (i.e. Windows computers will no longer try to download macOS
toolchains).
* Get the SDK working
Finishes out the remainder of the work required to successfully compile
a working blinky example.
* Fix UART stdio dependencies in Bazel build
Fixes some dependencies around pico_stdlib so that pico_stdlib links
properly and UART stdio works.
* Add linux support to Bazel build
* Get Bazel deps from registry
Adds external an external registry for resolving Bazel module
dependencies.
* Fix host configuration for picotool
Provides the appropriate defines for host builds to support the picotool
build.
* Remove -ffreestanding from Bazel toolchain
The -ffreestanding toolchain flag is quite strict, so remove it from the
Bazel toolchain.
* Remove unused .bzl file
* Reduce Bazel compiler flags
Cuts out most of the Bazel toolchain flags and only specifies the
bare-minimum set of flags. Also, adds wrapper linker flags for functions
the SDK wraps.
* Get USB serial working
Adds initial TinyUSB support and enough integration to get USB serial
working.
* Remove "Generated build file"
Removes comments that indicates BUILD.bazel files are generated. This
was used during initial bringup to indicate hand-crafted vs
automatically generated BUILD.bazel files.
* Do not build USB libraries unless configured
Prevents USB libraries from being built unless the build is properly
configured to use them.
* Switch to rules_cc toolchains
Moves toolchain configuration to use the new rules in rules_cc.
* Minor cleanup in parse_version.py
Cleans up trailing whitespace and runs the black formatter on
parse_version.py.
* Simplify constraint dimensions in Bazel build
Consolidates the class/chip constraint settings to be a single
constraint_setting with a config_setting that represents the rp2 class.
* Update pin of rules_cc in Bazel build
Includes a necessary fix for the target_compatible_with expression in
the cc_toolchain to work as intended.
* Move toolchains from pico.bzl to BUILD.bazel
Moves toolchain definitions from pico.bzl to BUILD.bazel to make them
easier to find and read.
* Run buildifier on Bazel build files
Fix trivial formatting issues by running buildifier on all BUILD.bazel
files.
* Make objcopy rule
Makes a simple objcopy rule to remove direct references to the ARM
toolchains.
* Fix link flags in Bazel build
Critical flags were not being applied to link steps. This applies -mcpu
and -mthumb to the link steps to make the produced binaries work again.
* Mention missing host build support
* Fix various Bazel library rules
* pico_bit_ops was incomplete.
* pico_double and pico_float were trying to link in the "none"
implementation.
* Extend Bazel build documentation
Improves documentation and comments across the Bazel build.
* Clean up auxilary tools in Bazel build
Switches genrules to use skylib rules to simplify things. Reworks
version header generation to use the Bazel module version rather than
parsing CMake.
* Update boot_stage2 Bazel build file
Moves `includes` to be enumerated on the correct library.
* Add WORKSPACE version fallback
WORKSPACE Bazel projects don't support querying module version, so add a
fallback of '0.0.1-WORKSPACE' so the build can succeed.
* Fix malloc handling in Bazel build
* Fix Bazel dependency cycle in pico_malloc
* Prevent malloc from being linked into boot_stage2
Prevents Bazel from ever trying to link malloc into the boot_stage2
binary.
* Remove custom bootloader platform
A dedicated boot_stage2 platform introduces a lot of complexity that
needs to be more thought-through.
