Cannot connect JLink to Red-V Thing Plus

Development Boards

I’m unable to connect to my RED-V ThingPlus. JLink fails to find the device. When I plug the device in, only the following item shows up under lsusb:

Bus 001 Device 032: ID 15a2:0073 Freescale Semiconductor, Inc. Kinetis Bootloader

And this is the output from sudo dmesg:

[14762.216571] usb 1-6: new full-speed USB device number 33 using xhci_hcd

Please check power, connection and settings.

When plugging the usb cable in, the orange light flashes briefly, and I saw the blue LED light up once when attempting to replug the USB. Double-tapping the reset button does not change the behavior of this connection.

That board requires Freedom Studio software (windows) or a Zephyr RTOS build environment set up to program the board and interface with it.

Try the Zephyr (or Freedom if you have a Windows machine around!) and see how that goes

I run into the same issue with zephyr. The Jlink software cannot find the device:

$ lsusb

$ west flash

When I plug and unplug the device, the only entry in lsusb that changes is ID 15a2:0073 Freescale Semiconductor, Inc. Kinetis Bootloader

I confirmed that I installed the JLink software from Segger (the link incorrectly takes you to the flasher tool, which seems to provide a much smaller set of udev rules and also didn’t help). I also uninstalled the latest version and installed the version described in the article, and it didn’t change the behavior. I’ve also rebooted my machine and reinstalled zephyr and still run into this issue. Any idea what could be missing? Is it possible I was given a board that’s missing the segger software?

TS-Russell, I would also try to use Freedom Studio, but it seems to require a corporate account to download (I couldn’t register with my personal gmail). I’m only doing this for personal exploration, so I’m not able to gain access.
