🤠 nRF54L15 Xiao USB West Flash How to;

Hi there,

So for the Beginner crew on here, Check out this guys video, it’s a basic how too, using the West Flash and in m_y Test environment the openocd is a preinstalled windows version, so I had to provide the path to it in the previous step, before in order to flash.

he’s a little dry but it gets the point across, flash without debugger or SWD hardware connections just USB.

this issue,
FATAL ERROR: required program openocd not found; install it or add its location to PATH

gave me this

I was able to duplicate his examples , for both video’s the GPIO one also.

Hi there,

Here is Another known youtuber that covers the MAC users perspective,
He also covers a few key observations in the process of building and flashing, a few incites into the new dev environment

Hi there,

So More of an OpenOCD question to the group…
Here is my OpenOCD log when I flash

What does yours look like…?

Depends what I’m flashing, but only 1 line really varies, essentially where it says NRF 54l.cpu halted due to breakpoint,

Otherwise I get something pretty much identical to what you show. I actually got channel sounding running earlier on the Xiao nrf54L15. Mostly…

here’s the contents of the .overlay I use to compile channel sounding for the xiao:

&radio {
    status = "okay";

    bt_hci_sdc: bt_hci_sdc {
        compatible = "nordic,bt-hci-sdc";
        status = "okay";
    };
};

/ {
	chosen {
		zephyr,bt-c2h-uart = &uart20;
	};
};
// can't have two devices on the 20 id at the same time as per documentation.
&pdm20 {
    status = "disabled";
};

&cpuapp_sram {
	reg = <0x20000000 DT_SIZE_K(256)>;
	ranges = <0x0 0x20000000  0x40000>;
};

but so far the results are… unsatisfactory as this device is 200mm from the reflector not 2180,
