Hi, I am using NuttX for micro-ROS on STM32 microcontroller on Olimex board. https://github.com/micro-ROS/nuttx_apps/blob/feature/foxy_rbs_one_sporadic_thread/examples/uros_rbs/main_rbs.c - sporadic thread 1 configuration: https://github.com/micro-ROS/nuttx_apps/blob/6f692d9bfcb0e3d1971e2b2a6448d1084d5a81ea/examples/uros_rbs/main_rbs.c#L367 - sporadic thread 2 configuration: https://github.com/micro-ROS/nuttx_apps/blob/6f692d9bfcb0e3d1971e2b2a6448d1084d5a81ea/examples/uros_rbs/main_rbs.c#L399 which is a very simple extension of the NuttX example for sporadic scheduling: https://github.com/micro-ROS/nuttx_apps/blob/feature/foxy_rbs_one_sporadic_thread/testing/ostest/sporadic.c In the experimental setup, the callback sleeps for 1ms and increments a counter. With this - I can test if budget enforcement is correct over a period of 10 seconds. - When I configure the application with one sporadic thread and one FIFO thread (with lower priority and 100% CPU utilization), budget enforcement works well. - When I configure the application with two sporadic threads and one FIFO thread (with lower priority and 100% CPU utilization) budget enforcement does not work any more. I tested with budget/period 10ms/10mms; 1s/5s. I came to the conclusion, that NuttX sporadic scheduling only works for one sporadic thread. For real applications, I would like to configure multiple threads with sporadic scheduling. Could you please check the implementation and give support? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
