i.MX50: Enable INTs in TZIC_INTCTRL

Hello Champs,

 

I'd like to make non-secure interrupts occur in i.MX50

 

Even though interrupts are enabled by setting EN bit of the TZIC_INTCTRL register, I can't get an interrupt from TZIC.

 

However I found following descriptions for TZIC_INTCTRL in the i.MX53 RM.

 

31bit NSEN MASK(0:NSEN bit unaffected , 1:NSEN bit updated)

16bit NSEN(0:Non-Secure interrupts disabled , 1:Non-Secure interrupts enabled)

 

Then I set the 31th and 16th bit in addition to EN, now I can get interrupts.

 

In the i.MX50 RM, these two bits are "This field is reserverd".

 

Should I just follow the way i.MX53 RM describes in order to make non-secure interrupts occur?

 

Best regards,

Nori Shinozaki
