Cortex, events inside a interrupt

 Cortex, events inside a interrupt

Good day,

IÂ'm starting a project with Cortex M3 (STM32F103R more exactly) using the RTX.
IÂ'm having troubles when I set some event ("os_evt_set" or "os_mbx_send") inside a interrupt. Every time I do that, the program jump to HardFault_Handler.
I rewrote my program using polling method (just for test), instead of interrup, and the program works fine.

How can I work with events inside a interrupt ?

Thanks.

use the isr versions of the routines. (isr_evt_set and isr_mbx_send)

Thanks Robert,
Im new with Keil and I have not seen this detail.

Per Westermark,
you already know where to go.

Of course you fail! But what does the manual say about the use of os_xxx function inside interrupt handlers?

Have you ever wondered why there is a function os_evt_set() and another called isr_evt_set()?

And why there is a os_mbx_send() and a isr_mbx_send() function?

Temper, temper.

It is when you are new with a product, that it is extra important to read the manual. If you only read an individual page here and there, you will never know what information you will miss.
