nRF9160 DK schematic sheet 2 missing pin names for WP and HOLD of nRF91_EXT_MEM in the On-board interface (far right page 2)
could someone post what nRF9160 pins are used?
nRF9160 DK schematic sheet 2 missing pin names for WP and HOLD of nRF91_EXT_MEM in the On-board interface (far right page 2)
could someone post what nRF9160 pins are used?
I dug into:
D:\ncs\v1.5.0\zephyr\boards\arm\nrf9160dk_nrf52840\nrf9160dk_nrf52840_0_14_0.overlay
board-control {
nrf_interface_pin_9_routing: switch-nrf-if9-ctrl {
compatible = "nordic,nrf9160dk-optional-routing";
control-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
status = "disabled";
};
io_expander_pins_routing: switch-io-exp-en {
compatible = "nordic,nrf9160dk-optional-routing";
control-gpios = <&gpio0 14 GPIO_ACTIVE_HIGH>;
status = "disabled";
};
external_flash_pins_routing: switch-ext-mem-ctrl {
compatible = "nordic,nrf9160dk-optional-routing";
control-gpios = <&gpio0 19 GPIO_ACTIVE_HIGH>;
status = "disabled";
/* status = "ok"; to switch access the nor chip? */
};
};
Who knew I'd be modifying nRF52840 code to gain access to the nor memory with the nRF9160 and I was sneaking up on kconfig... Now I'm going to find the definition of all the kconfig macros like external_flash_pins_routing
