Implementing a mutex

[Bret Foreman]

I need a mutex and I found this information at the ARM site: infocenter.arm.com/.../index.jsp

Is there anything I should be aware of in using this technique to implement a mutex?

Hi there,

Are you using the SoftDevice?

If so, there are already SVCs provided by the SoC framework that implement mutexes and critical regions:

sd_mutex_new sd_mutex_acquire sd_mutex_release

sd_nvic_critical_region_enter sd_nvic_critical_region_exit
