a very tiny RTOS

demo

Run as Linux app on x86_64 linux HOST

make linux_app_x86_64
./out/linux_app_x86_64/linux_app_x86_64.elf
press CTRL+C to show RTOS status

Know issue: Crash during RTOS resources init sometimes.

Run by x86 Qemu

make x86_qemu
make linux_app_x86_64
qemu-system-i386 -nographic -m 64M -kernel out/x86_qemu/x86_qemu.img

Know issue: crash for tss invalid setting on new Qemu version

Workarround: use old Qemu. E.g. Qemu v2.0.0

TODO

Try to fix Know issues

STM32 version can work on my dev board with additional code for hw setup. It needs to clean up the code and enable it with ARM Qemu for users who have no HW.
