cortex-R5 ipi address in system-user.dtsi file

Jump to solution

Hi. 

I have a question about ipi address.

 

I knew that Cortex R0 ipi address begin is 0xFF310000 ans R1 ipi address begin is 0xFF320000. 

 

but example dtsi file (openamp-overlay.dtsi) has another IPI address, 0xFF34000000. I know  that 0xFF3400000 is PL0 IPI address.

 

I try to switch 0xFF310000 to 0xFF340000,  openAMP examples are not working. 

 

What is mean 0xFF3400000 IPI address in dtsi file?

 

Regards

 

Shin.

0xFF3400000 IPI (i.e. PL0 IPI) is used for APU since the default APU IPI is used by PMUFW and ATF.
