I've got a Thingy:91 plugged into my computer and can see its USB terminals (/dev/tty.usbmodem143101 and /dev/tty.usbmodem143104). I can also see the "ZEPHYR USB" volume and its contents. This indicates to me that the connectivity bridge running on the Thingy:91's nRF52840 is operational.
I'm attempting to write out to UARTE0_NS which has been configured as per the following Zephyr config:
&uart0 {
compatible = "nordic,nrf-uarte";
current-speed = <115200>;
status = "okay";
tx-pin = <18>;
rx-pin = <19>;
rts-pin = <20>;
cts-pin = <21>;
};
I'm also flashing the SPM sample, which I *think* permits the use of UARTE0_NS.
My program loops on waiting for the transmission to end. Am I missing anything so far?
Thanks.
