I haven't connected any devices apart from my multimeter to my SLSTK2000A (EFM8UB1 kit) yet, but I have been tinkering with the sample code using the on-board LED.
I was using the Linux version of Simplicity Studio in Ubuntu 16.04 (Simplicity Studio 4). It was working fine one evening while I had it plugged in via the kit USB connector, and all of a sudden it wouldn't flash it anymore. I then plugged it into my laptop that runs Windows 10, and it won't work on that either.
The SLSTK2000A kit looks normal (the LCD displays the Silicon Labs logo, the blue LED to the left comes on, and the yellow LED to the left blinks like it usually does).
It detects it correctly when I use the 'Add Device' option, but it just won't upload the code.
I really hope it isn't permanently damaged. Thank you for your time...
This may seem like a tedious step, but can you go to the Launcher and select the Devices tab. From there select Refresh to see if the board is displayed once again. After the board is detected and you highlight the top level J-Link as shown in the picture. From there, go back to the IDE and select the Debug icon. This should load the flash and start the debugger.
If it does not connect, can you then try going to the project settings and selecting the correct part (it was probably correct, but just trying it again). Select the Board / Part / SDK as shown in the figure below and select the correct part.
Thanks for your reply. I tried that, and it was set to the correct board, but the Universal Bee was not listed in the board options. The correct MCU was available in the MCU options list, though.
This is the error I get when trying to debug.
I just let it try to install something that like firmware tools for the kit (it suddenly asked me if I wanted to download it), it said it failed, and now the kit can't be detected at all. The yellow LED I mentioned to the left no longer comes on. The LCD is now blank.
Have you tried to uplug and plug the USB connection to the PC after the failed download attempt? If so, does it try to download again and pass?
Try that and let me know if it recovers.
From the launcher select to Change the adapter firmware.
If that doesn't work please submit a support ticket so that we can determine if the board is bad.
Thank you. It successfully reinstalled the adapter firmware and now the LCD/yellow LED are working again.
It still won't upload any code samples, though.
That is good news. Let's start from the beginning just to make sure. Can you select the blinky example project and bring it into the IDE? Try to build, download, and run the code to see if that basic project works?
Yes, and I am now able to select the board in the project properties as you said to.
I have now created the Blinky sample project, but I get the following error:
'Failed to connect to device
TCF error report:
Error text: No adapter found
Error code: 131073'
In the Launcher window can you go to your devices tab and select Refresh? See if the debugger shows up there. Highlight it and then go to the IDE and try to download? If you can send a screen capture of the Device window that would be helpful too.
Ok. It's giving me the same error.
