Hi! Looks like druntime fork dedicated "to support almost any system" (https://github.com/denizzzka/druntime) works well with ARM Cortex-M3 backend! Almost all unittests is passed on QEMU emulated hardware (except threads and fiberes, see more: https://github.com/denizzzka/d_c_arm_test/issues/5) So, it will be cool if some real project will have its firmware implemented on D! ARM Cortex or MCU based on RISC-V is preferred, but another architectures is also appropriate. Any ideas?

(Time & date, Bluetooth communication/integration with phone, heart rate measuring, etc.) I wanted to start on that a while ago but haven't gotten around to it yet. Now there is even OTA flashing shipped with the watch in the included (community) OS which makes it even easier as you don't need to get a flashing device + cable anymore. (It's very cheap, 15€ for one with integrated debugger by a big trusted company for open source/personal use, but putting the cable in the watch and flashing with it is kind of a pain) [1]: https://www.pine64.org/pinetime/

It looks like this: $ qemu-system-arm -machine mps2-an511 -nographic -rtc clock=vm -icount shift=2 -semihosting -kernel firmware.elf unexpected pointers 0x2184e008 and 0x21865008 Not safe to migrate Fibers between Threads on your system. Consider setting version CheckFiberMigration for this system in thread.d 28 modules passed unittests $ There are a few more unfinished parts but they are not fundamental: - disabled demangle tests (demangle consumes huge memory amounts sometimes, https://github.com/dlang/druntime/pull/3262) - disabled some TickDuration tests - don't know how to fix it, but remember what TickDuration is deprecated - core.sync.condition is not implemented - more what is not used in current unittests but depends from OS (just errors is not triggered in this case) More info at: https://github.com/denizzzka/d_c_arm_test (look into "issues" section)
