2025-08-25mimxrt: Restructure nxp_sdk to match official mcux-sdk.Yilin Sun
The official mcux-sdk follows a slightly different structure to the current nxp_sdk submodule, with many drivers moved to a common location. To ease updating the newer versions of the SDK and/or add new families the nxp_sdk submodule has been updated to follow the structure of mcux-sdk, just trimmed down to families used here to considerably reduce the size.

2025-07-24lib/pico-sdk: Fix Pico SDK fetching develop picotool.Phil Howard
SDK 2.1.1 shipped with PICOTOOL_FETCH_FROM_GIT configured to fetch the "develop" branch. This broke downstream CI, which was trusting Pico SDK to fetch the correct version. RPi have added a "2.1.1-correct-picotool" tag which fixes this. lib/pico-sdk: Bump to "2.1.1-correct-picotool" tag. Signed-off-by: Phil Howard <github@gadgetoid.com>

2025-05-09lib/littlefs: Fix string initializer in lfs1.c.Angus Gratton
Avoids the new Wunterminated-string-literal when compiled with gcc 15.1. It would be preferable to just disable this warning, but Clang -Wunknown-warning-option kicks in even when disabling warnings so this becomes fiddly to apply. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
2025-05-07lib/littlefs: Reuse existing CRC32 function to save space.Daniël van de Giessen

2025-05-07lib/littlefs: Update LittleFS to v2.10.2.Daniël van de Giessen
Going above the root directory (/../foo) now gives an error. This is an intentional change made by LittleFS. It required a update of the testsuite and is a (minor) compatibility break. Signed-off-by: Daniël van de Giessen <daniel@dvdgiessen.nl>

2024-09-23lib/libffi: Update libffi to 3.4.6.Alessandro Gatti
Libffi is updated to the latest stable version (v3.4.6) as the version of libffi that was linked by the repository predates the introduction of RISC-V processors (both 32 and 64 bits). This is necessary as the packaged version of libffi used by the CI for RISC-V 64 turned out to simply not work correctly, whilst a source-built version of libffi worked just fine.

2024-09-19all: Remove tinytest component.Damien George
With the recent qemu (d9a0fdda9a7b0db55c1115b55bb1b83cd5ce739c and 0426934969d06aa649ba903f5408cb331b5b9c2d) and zephyr (05cad7b56f5d460db26a468a05bfdeabe4a656db) changes to how their tests are run, two things became unused: - The tinytest framework, which embedded a set of tests and their expected output within firmware, so these tests could be run stand-alone. - The `--write-exp` and `--list-tests` options to `tests/run-tests.py`, which were needed primarily to generated the expected test output for tinytest (also the associated `tests/run-tests-exp.py/.sh` scripts are now unused). This commit removes the tinytest component and all its helper code. This eliminates a maintenance burden. Signed-off-by: Damien George <damien@micropython.org>

2024-06-06lib/libm: Define _IEEE_LIBM only if not set.Alessandro Gatti
fdilibm was originally meant to see _IEEE_LIBM defined from outside the libm code, not it being hardcoded in. Picolibc assumes this assumption holds true and attempts to define itself, conflicting with the existing definition. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>

2024-05-31lib/libm: Do not force floating point type size evaluation.Alessandro Gatti
Since C99, `FLT_EVAL_METHOD` should be left for the compiler/libc to define. Its redefinition breaks compilation with picolibc as the target's libc, since it defines said symbol in math.h before the libm define is evaluated by the compiler. In its place, there is a check to make sure floating point type sizes are what are expected to be, triggering a compilation error if those assumptions are no longer valid.

2024-03-16lib/berkeley-db-1.xx: Update submodule URL and version.Damien George
This updates the berkeley-db-1.xx submodule URL to a repository hosted under the micropython organisation, and makes the following changes: - Moves the berkeley-db header files to a single directory within the submodule, and references all these headers with a much fuller path, which prevents symbol clashes (eg with esp32 and queue.h). - Removes unused/non-working files from berkeley-db, which removes all symlinks in that repo (symlinks don't play well under Windows). - Allows injecting an external configuration header into berkeley-db, so the configuration doesn't have to be provided by -Dxx=yy flags to the compiler (and possibly clashing with other symbols). - Removes the advertising clause from the BSD 4-clause license of berkeley-db (see relevant commit and README.Impt.License.Change for details).

2024-03-15lib/open-amp: Add OpenAMP submodule.iabdalkader
OpenAMP framework provides a standard inter processor communications infrastructure for RTOS and bare metal environments. There are 3 major components in OpenAMP: libmetal, remoteproc and RPMsg. libmetal provides abstraction of the low-level underlying hardware, remoteproc is used for processor Life Cycle Management (LCM) like loading firmware, starting, stopping a core etc., and RPMsg is a bus infrastructure that enables Inter Processor Communications (IPC) between different cores.
