To clean things up, I'd be happy if you could accept one of the answers you've received, even your own, if you feel that was the best one.

Hi, I've entire toolchain running under OS X. It uses Eclipse as IDE, jlinkexe as flasher and jlinkgdbserver as debugger with arm-none-eabi-gdb.

Your idea to port it on Xcode in fantastic.

Happy to contribute to Xcode porting.

Bret,

I've gotten my JLink's working under Win 7 64-bit under VirtualBox on my MBP now. This appears to be a combination fo hand installing the drivers, making sure I copy the JLink driver to the Keil driver location, AND...making sure that the JLink is set to SWD in Keil. I noticed earlier today it seems to think its a JTAG unless I switch it -- not sure if this is something to do with sensing its capabilities under VirtualBox?

Maybe the above gives you some pointers on Bootcamp? PM me if you I can help.

Cheers,

-marc

P.S: I'm working on getting the entire toolchain working under OSX and XCode natively -- stay tuned!

Just for future reference, and especially considering your other update, I'm pretty sure it does show up in Device Manager, under USB Devices, as shown in the screenshot I posted in another answer.

As I said in a comment to another of your posts, the J-Link Lite isn't supposed to show up as a serial port, so this is actually to be expected. You should also be able to use it directly from Keil.

Anyway, I'd be happy if you could mark this answer as accepted, so that the discussion shows up as resolved. :-)

Here's an interesting update. I can download to my target using the JLink-Lite now that I know what to look for in nRFgo. The JLink does not show up in the device manager but it is accessible from nRFgo. Kind of counter-intuitive but I'll take functionality over elegant design.

On a Macbook you can natively run jlink. I've installed version 4.69b on MBP, runs well, remember only to disable CDC using Segger Mac OSX CDCDisable bash script.

As you can see, the JLink-Lite simply does not show up in the Device Manager at all. I do see the JLink-Lite in the Device Manager on a Dell laptop.

The J-Link Lite doesn't show up as a COM port, it's using another way of communicating. Please see my other answer, which I hope can help you.

Ole Morten — Fri, 28 Jun 2013 05:09:33 GMT

This may be a stupid answer, but beware that a stand-alone Segger doesn't show up like the Evaluation Kit and Dongle do in nRFgo Studio's Device manager. Instead it is usable from nRF51 Programming and from Module - nRF51822 selection, as shown in the attached screenshot.

If this is not the problem, can you please show me a screenshot of your Windows Device Manager? Do you see a J-Link Device at all, as in the other attached screenshot?

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.

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

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 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.

Bret Foreman — Thu, 27 Jun 2013 21:29:21 GMT

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?
