Hi:
I checked the zephyr.dts file, but I couldn't find the addresses for interrupt-controller(0xe000e100), timer(0xe000e010), and memory(0x20000000) in the nRF9160 Product Specification (nordicsemi.com).
#address-cells = < 0x1 >; #size-cells = < 0x1 >; compatible = "nordic,nrf9160-sica", "nordic,nrf9160", "nordic,nrf91", "simple-bus"; interrupt-parent = < &nvic >; ranges; nvic: interrupt-controller@e000e100 { #address-cells = < 0x1 >; compatible = "arm,v8m-nvic"; reg = < 0xe000e100 0xc00 >; interrupt-controller; #interrupt-cells = < 0x2 >; arm,num-irq-priority-bits = < 0x3 >; phandle = < 0x1 >; }; systick: timer@e000e010 { compatible = "arm,armv8m-systick"; reg = < 0xe000e010 0x10 >; status = "disabled"; }; sram0: memory@20000000 { compatible = "mmio-sram"; reg = < 0x20000000 0x40000 >; };
