19817: compile_and_test_for_boards: Add no-compile flag r=benpicco a=MrKevinWeiss ### Contribution description Since we have a no-test flag that prevents executing tests, I think a no-compile flag is a nice compliment. Why? Well if I want to use this script for running multiple boards at the same time, RIOT is not so great handling parallel compile steps with conflicts on lockfiles happening, mostly due to packages. With this I can compile a list of boards sequentially, then flash and run tests in parallel, skipping the compile step. ### Testing procedure Run the following once to compile and clean: ``` ./dist/tools/compile_and_test_for_board/compile_and_test_for_board.py . native --applications tests/sys/shell --clean-after ``` Then try to run without the compile step and it should fail due to lack of the binary ``` ./dist/tools/compile_and_test_for_board/compile_and_test_for_board.py . native --applications tests/sys/shell --no-compile ``` ### Issues/PRs references 19826: ztimer/periodic: reinit remove from right clock and handle aquired ztimer r=benpicco a=kfessel ### Contribution description #19806 added some retinit handling for ztimer periodic removing the timer from the new clock This tries to detect if this is a reinit and remove the timer from the old clock this also removes the ztimer_acquire/_release handling by removing now calls in favour of set return value and now values that are allready in ztimer, that also has the potential to reduce the jitter of the periodic calls and bus-usage (for cpus that take their time to get "now") ### Testing procedure read run tests/sys/ztimer_periodic ### Issues/PRs references Fixes #19806 19841: boards/adafruit-itsybitsy-nrf52: Add configuration for DotStar LED r=benpicco a=jimporter 19842: cpu/stm32: fix ld script for SRAM4 r=benpicco a=gschorcht ### Contribution description This PR fixes the LD script for STM32. Since the CCM and SRAM4 length are defined as symbols with perifx `_`, the LD script didn't use them correctly. Instead of using `ccmram_length` and `sram4_length`, `_ccmram_length` and `_sram4_length` have to be used. Furthermore, the location counter for the SRAM has to be set to the beginning of SRAM4 to work. BTW, I don't understand why the `ccmram` region is defined. There is no section definition that would use it to place code or data with attribute `.ccmram.*` there. Without the fix in this PR, defined symbols in `tests/sys/malloc` for the `b-u585i-iot02a` board were: ```python 00000000 T _sheap2 <== wrong start position because of wrong location counter 28000000 T _eheap2 <== wrong end position because of `sram4_length` is 0. ``` Although the `tests/sys/malloc` crashes for `b-u585i-iot02a` at the end of the heap (known problem, see [here](https://github.com/RIOT-OS/RIOT/pull/17410#issuecomment-996556823)), it uses only the backup RAM before it crashes: ``` Allocated 512 Bytes at 0x200bf600, total 756072 Allocated 512 Bytes at 0x200bf818, total 756592 Allocated 512 Bytes at 0x200bfa30, total 757112 Allocated 512 Bytes at 0x200bfc48, total 757632 Allocated 512 Bytes at 0x40036408, total 758152 Allocated 512 Bytes at 0x40036610, total 758672 Allocated 512 Bytes at 0x40036818, total 759192 ``` With the fix in this PR, defined symbols in `tests/sys/malloc` for the `b-u585i-iot02a` board are: ```python 28000000 T _sheap2 <== correct start position 28004000 T _eheap2 <== correct end position ``` `tests/sys/malloc` also crashes for the `b-u585i-iot02a` at the end of the heap, but it uses also the SRAM4 before it crashes. ``` Allocated 512 Bytes at 0x200bf600, total 756072 Allocated 512 Bytes at 0x200bf818, total 756592 Allocated 512 Bytes at 0x200bfa30, total 757112 Allocated 512 Bytes at 0x200bfc48, total 757632 Allocated 512 Bytes at 0x40036408, total 758152 Allocated 512 Bytes at 0x40036610, total 758672 Allocated 512 Bytes at 0x40036818, total 759192 Allocated 512 Bytes at 0x28000008, total 759712 Allocated 512 Bytes at 0x28000210, total 760232 Allocated 512 Bytes at 0x28000418, total 760752 ... Allocated 512 Bytes at 0x280038e8, total 774272 Allocated 512 Bytes at 0x28003af0, total 774792 Allocated 512 Bytes at 0x28003cf8, total 775312 ``` ### Testing procedure 1. Flash `tests/sys/malloc` and use `MAX_MEM` limit to stop `malloc` before the crash: ``` CFLAGS='-DMAX_MEM=774800 -DCHUNK_SIZE=512 -DDEBUG_ASSERT_VERBOSE' \ BOARD=b-u585i-iot02a make -j8 -C tests/sys/malloc flash ``` Without the PR it crashes at the end of the backup RAM. With the PR it works. 2. Check `_sheap2` and `_eheap2` with ``` nm -s tests/sys/malloc/bin/b-u585i-iot02a/tests_malloc.elf | grep heap2 | sort ``` Without the PR it will be: ``` 00000000 T _sheap2 28000000 T _eheap2 ``` With the PR it should be: ``` 28000000 T _sheap2 28004000 T _eheap2 ``` ### Issues/PRs references Co-authored-by: MrKevinWeiss <weiss.kevin604@gmail.com> Co-authored-by: Karl Fessel <karl.fessel@ovgu.de> Co-authored-by: Jim Porter <jporterbugs@gmail.com> Co-authored-by: Gunar Schorcht <gunar@schorcht.net> |
