Hello, I solved my issue by changing my J-Link V8 to J-Link V9. V9 has built-in capability for RTT and there aren't anymore overflows in SystemView. Thanks for the support via email. Regards

Hello, I have big overflows with segger sysview. Is it possible to modify RTT/SYSView configuration so as not to report OS_Use OS_Unuse events, so as to limit bandwith usage? Thanks

Hi, Okay i found the API tables and OS_Delayus() seems to work before call of OS_Start() I cannot reproduce the bug I had with OS_Delayus for the moment, maybe a stack corruption problem. I have another issue with software timers. In the manual, the API functions for software timers claim that OS_CreateTimer() and OS_StartTimer() can be called before OS_Start(). So I use it this way: Source Code (9 lines) If I call InitTimeout() before OS_Start(), I never enter the callback. If I call InitTimeou…

Hello, Does the function OS_Delayus() work correctly before OS_Start() is called? Do you have a list of all the embos functions than can be used before the OS is started? Best regards

Which start project do you use? Custom project Our code is : OS_Delayus(1); //CS disable time >50ns pCSpin->set( false ); OS_Delayus(1); //CS setup time >150ns We are stuck in OS_Delayus(1) When we debug step by step here, the program keeps entering and exiting OS_GetTimeCycles(), like it's not leaving …

Thanks for your confirmation. I have added a safe +1ms to the user requested period.

Hi, with embOS on stm32f103 when I create a timer with a period of 1ms ex: C Source Code (13 lines) what is the possible period between StartTimer() and TimerCallback(). Does it depend on the delay between OS Tick and call to StartTimer? Currently I am experiencing random periods between 0 and 1ms.
