Orange Pi - Allwinner H3 Interrupt base address (baremetal)

varghese

I am writing a baremetal Timer/Interrupt code

Allwinner H3 datasheet does not have any Interrupt Register List  , but A13 has some details and its base address is 0x01C20400 ..

from linux H3 dtsi files
gic: interrupt-controller@01c81000 {
                        compatible = "arm,cortex-a7-gic", "arm,cortex-a15-gic";
                        reg = <0x01c81000 0x1000>,


But I tried writting to 0x01C20400 & 0x01c81000   both are not writting , it seems something wring with the address ..   

Anyone has any idea on this ?

Allwinner A13 is cortex-a8, gic (Global Interrupt Controller) other. Allwinner H3 has GIC-400.
