nRFgo can't see J-Link Lite CortexM board

I'm happy with the status of my app on the evaluation board and I'm ready to start downloading it to my target board. I plugged the Segger J-Link Lite CortexM board into one of my USB ports and the (Windows 7) driver seemed to load correctly. However, I can't see the J-Link board in the nRFgo tool. Is it required that I have my target device connected to the J-Link in order for nRFgo to see the J-Link? Note that nRFgo can see other Segger devices in the eval board and the BLE dongle.

I notice that Segger has a number of debug and management tools for download on their website but I hesitate to add any more software into what is already a complex mix without a recommendation from others in the same situation.

  • I just thought of another thing - I checked the Windows Device Manager while plugging and unplugging the J-Link board and I don't see any new devices appear in the list of Com ports. Maybe I have a bad board?

  • I'm running Windows 7 on a Macbook. I tried the board on a Dell laptop running Windows 7 and it appears in the device manager. So it's a driver problem. I'll put in a ticket.

  • I've been trying to get it to run in 64-bit Windows 7 on an MBP under VitualBox without success.

    I finally got the driver issues (all) resolved and now for some reason there seems to be lower level USB issues that the SEGGER driver reports (something about asserting a certain level...TD0 if memory serves me correctly?).

    Are you trying in Bootcamp or under a virtualization layer out of interest?

  • I'm using Bootcamp. And it's 64-bit Windows. The Dell is old, probably 32-bit. That might be a factor.

  • I've found the installer for 64-bit flakey. I literally cracked open the MSI in WinRAR and hand installed the driver.

    I would love to get my full Nordic environment running on my MBP -- if anyone has (with Keil, but I'd consider another IDE) I'd love to hear from there.
