FreeRTOS v 7.1

Posted by manpreethazrah on January 21, 2016

Hi , I am using coocox coIDE for stm32f4 Discovery board. FreeRTOS v7.1 and 6.9 is present in the librairy, v6.9 is working fine but when i use v7.1 in my project while build there is an compiler error related to thumb instruction and floting point. Error is as below: Error: selected processor does not support Thumb mode vstmdbeq r0!,{s16-s31}' Error: instruction not allowed in IT block --stmdb r0!,{r14}' Error: selected processor does not support Thumb mode vldmiaeq r0!,{s16-s31}' Error: instruction not allowed in IT block --ldmia r0!,{r4-r11}'

Please help me out to shortout the problem.

The versions you are using are old so it will be difficult for anybody to answer directly from experience, especially as there was never a version 6.9, but as a guess I would say the compiler options were wrong in the project using v7.1.
