Re: Direct ISR support on ARC

Thank you Ruud for sharing and sorry for replying late.
You nail it: I was checking Zephyr 2.0.0. I will get the latest copy and give it a try.

Many thanks again,
Justin

Hi Justin,

 

What version are you using? ARC support for direct interrupts was added in v2.1

(and note that Z_ARCH_IRQ_DIRECT_CONNECT was renamed to ARCH_IRQ_DIRECT_CONNECT).

 

Regards,

 

Ruud.

Hi,

 

It appears to me that there is no support of 'direct ISR' by Zepher for the ARC processors: I do not see the definition of Z_ARCH_IRQ_DIRECT_CONNECT in the irq.h for ARC. 

Could someone please share why it is not supported?

 

Thanks,
Justin
