port st ARM7 with ride

Hello, I’m trying to port the freertos to str ARM 7 on RIDE. I took the one with IAR and did some changes for being compile with RIDE and I force the task to run in ARM mode because in thumb mode it is not working properly. port.c : #define portINITIAL_SPSR 0x1f In this case task are working properly, TaskSuspend-TaskResume is working properly, queue is working properly but vTaskDelayUntil is not working properly and I can’t understand why. Could you explain changes that I must dio to use properly the freertos in thumb mode or how to port to ride. Thanks a lot

What is RIDE? Can you post a short code snippet to show how you are using vTaskDelayUntil()?
