Hi, want to use RTX V4.82 on STM32G071 Nucleo board.Two threads running, one thread calls osDelay(250)... and goes into os_error().This because in cmsis_os.h there is osFeature_Wait defined as "0".So, no RTX is possible (mailboxes, semaphores aso)Why is it defined as "0"?Best regards
#define osKernelSystemId "RTX V4.82" ///< RTOS identification string #define osFeature_MainThread 1 ///< main can be thread #define osFeature_Pool 1 ///< Memory Pools available #define osFeature_MailQ 1 ///< Mail Queues available #define osFeature_MessageQ 1 ///< Message Queues available #define osFeature_Signals 16 ///< 16 Signal Flags available per thread #define osFeature_Semaphore 65535 ///< Maximum count for \ref osSemaphoreCreate function #define osFeature_Wait 0 ///< osWait not available #define osFeature_SysTick 1 ///< osKernelSysTick functions available
Sorry, turned out to be a stack size error. Stepping through code showed - printf... - that thread needed 576 bytes stack, but only 512 were available.This lead to wrong call address (osWait() instead of osDelay(), so there osFeatureWait==0 forced osError()...Sorry for bothering you..Juergen
