* Make STM compile again and update toolchain. The binary is too big for the flash. WIP * Making progress with OSFS, still WIP * more progress, still too big. Adding RAK3172 to the equasion * Make STM compile again and update toolchain. The binary is too big for the flash. WIP * Making progress with OSFS, still WIP * more progress, still too big. Adding RAK3172 to the equasion * still too big * minimize build * trunk fmt * fix a couple of symbol clashes * trunk fmt * down to 101% with a release vs. debug build and omitting the flash strings * fix compilation * fix compilation once more * update protobufs linkage * - Toolchain updated - Fixed macro error * silence compiler warning note: do something about this assert... * new toolkit and fix Power.cpp * STM32WL make it fit (#4330) * Add option to exclude I2C parts The I2C hals and related code uses a significant amount of flash space and aren't required for a basic node. * Add option to disable Admin and NodeInfo modules Disabled by default in minimal build. This saves a significant amount of flash * Disable unused hals These use up significant flash * Add float support for printf for debugging Makes serial look nice for debugging * This breaks my build for some reason * These build flags can save a bit of flash * Don't disable NodeInfo and Admin modules in minimal build They fit in flash * Don't include printf float support by default Only useful for debugging --------- Co-authored-by: Adam Lawson <dev@goshawk22.uk> --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com> Co-authored-by: Adam Lawson <dev@goshawk22.uk>
