micro-ROS uses clock_gettime() and added a custom one when there is no real posix timers support. The latest newlib missed the func proto and caused build error. This patch fixed this issue. Tested on both pico and pico2. In this timer.h #if defined(_POSIX_TIMERS) ... int clock_...
…work Running posix CPU timers in hard interrupt context has a few downsides: - For PREEMPT_RT it cannot work as the expiry code needs to take sighand lock, which is a 'sleeping spinlock' in RT. The original RT approach of offloading the posix CPU timer handling into a high priority th...

aSys_setalarm is related to the POSIX alarm system call, but the relation is a distant one. The POSIX call is mostly handled by the process manager, which maintains a queue of timers on behalf of user processes. The process manager uses a sys_setalarm kernel call when it needs to have...
