commit e9913a1579d07c3967fecbfb5b8798e94944e45a Author: Marco Casaroli <[email protected]> AuthorDate: Sun Sep 27 11:56:33 2026 +0200 tools/nxflat: Add a driver for the NXFLAT test suite. Building an NXFLAT module takes four tools in sequence, and there was no way to exercise them without a board. testsuite.sh builds every module of apps/examples/nxflat/tests for cortex-m3 against a configured tree's headers, and reports the stage each one stopped at and the relocations it carried.
