Disable all hardware interrupts in MQX

aakankshagaur — Mon, 27 Jul 2015 13:54:56 GMT

Hello,

I want to perform RAM test at Run time. So I try to disable all MQX interrupt before jumping to the RAM test code using

_int_disable()

RAMTest()

_int_enable()

But still the MQX interrupt happen and my code stuck in between.

So could somebody tell me how to disable all the MQX interrupt even with priority levels upto 7 also before jumping to RAM test code.

Or is there any function or preprocessor directives in MQX to enter and exit from critical section?

These functions (_int_disable and _int_enable) enable and disable ALL interrupts EXCEPT NON MASKABLE interrupts.

I think you can try _mqx_exit(0), this function disable all the interrupts.

Regards

Daniel

Hi Daniel,

Thanks for your response but I guess _mqx_exit(0) would not help me because I have many periodic task in the code. And the task which would perform RAM Test will get executed in every 20 milliseconds.
