Hi i am trying to build Freertos task library to use on raspberry pi 4 which use ARM cortex A72 as processor . By building the project i got erro in tasks.c “portDisableinterrupt() : no such instruction” i tried to change the #define of these inatruction from task.h to tasks.c but i get the same problem . I used portable/GCC/Armc0 as port .
Can someone may be help me?
Thanks

That is not a function I’m familiar with. Where did I the port come from? Is it similar to our Arm Cortex-A5x port?
