- prefer "pico_cmake_set(var, value)" over "// pico_cmake_set var = value"
- prefer "pico_cmake_set_default(var, value)" over "// pico_cmake_set_default var = value"
- move these inside the header include guards as CLion complains
Note that the macros are defined in "pico.h" however that is not explicitly included by the board headers; this
will probably confuse some VS code syntax highligting, so lets see how it looks - i'd prefer to avoid having
to include a header just for this
* Propogate non-default pico_cmake_set_default values through to compile definitions
Add PICO_BOARD_CMAKE_OVERRIDES common scope variable, to contain any pico_cmake_set_default
CMake variables which have been overwritten. This allows passing CMake arguments to the
build, without needing extra target_compile_definitions.
Also add pico_cmake_set_default PICO_RP2350_A2_SUPPORTED to enable/disable the E10 abs-block fix
* Fix more board files missing pico_cmake_set_default PICO_RP2350_A2_SUPPORTED
* Apply @lurch's patch to check_board_header.py
* Update config-extraction scripts to work with multiple chips
* Standardise wording between common options
* Various config-related fixes
* Update pico_rand to use correct busctrl_hw struct-name
* Don't start config descriptions with "The ..."
* 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
* Fix various non-GCC warnings (no effect on GCC)
* Reduce use of typeof since non GCC compilers may not support it
* Introduce PICO_C_COMPILER_IS_GNU, PICO_C_COMPILER_IS_CLANG, PICO_C_COMPILER_IS_IAR to CMake as if (CMAKE_C_COMPILER_ID STREQUAL "xxx") is a bit verbose
* Use "unified_asm" macro for all inline asm (it is "volatile __asm" on GNU with a .syntex unified)
* Use NOLOAD instead of COPY in linker scripts (arguably more correct anyway)
* Use the same style for setting _etext in all 4 linker scripts (to the beginning of .data). Clang aligns .data on a 16 byte boundary. Note ideally we'd
add a new symbol __data_source, however that would break backwards compatibility with existing user linker scripts
* Use "a" for .stack, .heap sections because clang complains otherwise, and they are explicitly NOLOAD anyway
* Avoid duplicating __sev, __wfe, __wfi which Clang sometimes seems to provide as built-ins
* Add missing kitchen_sink_blocked_ram binary
* Allow build with LLVM Embedded Toolchain Form ARM v 14.0.0 (unsupported atm)
Add a -nostdlib specifically for the check to ensure that it builds
successfully.
The -nostdlib isn't needed normally, because linking against the pico
SDK will add in definitions for the previously-missing function
* Add missing DREQ_s
* store actual clock frequency in clock_configure (fixes#368)
* use dma DREQ values defined in dreqs/dma.h
* Fix hw_is_claimed, and add xxx_is_claimed APIs
* Add some PIO irq helper methods
* Add DMA channel IRQ status getter and clear methods
* Implement the correct PIO IRQ status/clear methods (good to have methods here as the h/w interrupt registers are super confusing)
* fix pico_multicore dependencies
* add missing wrapper func __aeabi_f2d
* Further DMA/PIO IRQ API cleanup (and review fixes)
* add PICO_INT64_OPS_IN_RAM flag
* Change some cmake output to DEBUG level
Make SDK build more consistent with other libraries (use an INTERFACE marker library for inclusion tests)
Add PICO_SDK_PRE_LIST_FILES, PICO_SDK_POST_LIST_FILES build vars
* fix typo
* remove leftover debugging message
* pico_stdio_usb: be more explicit about includes, fix warning (#257)
* pico_base: NDEBUG backwards for absolute_time_t (#255)
* pico_util: missing extern C in queue.h (#249)
* build: remove -march which was masking -mcpu, now SVC available (#253)
