mbed is being turned off soon, so looking at Keil Studio Cloud. (We use the online ecosystem to ease the lab and installation burden on our students).
Copied the mbed2-example-blinky project from Studio Cloud (target: NUCLEO-L031K6). Hit "Run Project". I get message saying project compiled. Then a message "mbed2-example-blinky failed to run".
So, now what?
PS: I have praised mbed to everyone I have met for 10+ years due to its ease of use and how it almost always "just works", based on my very first usage all those years ago. RIght now, Keil Studio Cloud is looking to be a horrible replacement. Get with it ARM.
What is mbed2-example-blinky supposed to run on? What hardware? What debugger? I'm not familiar with cloud based dev myself, but there are details you could have provided.
NUCLEO-L031K6 as stated in my post. It's a NUCLEO, so the ST-LINK programmer/debugger. (Yes, my Nucleo ST-LINK is running the latest firmware, and I have selected the "DAPLink if available" setting in the project as instructed by the documentation.)
Supposedly, you can program, debug, monitor, etc the target straight from Studio Cloud. That is what I am trying to do.
The Studio Cloud will build a .bin file that downloads to my PC. Then, I can program it to my Nucleo board and it appears to work. But the online mbed IDE has been able to do that since 2009.
There's some troubleshooting information available here: https://developer.arm.com/documentation/102497/1-5/Known-issues-and-troubleshooting/Troubleshooting. In particular, the information on connect mode "underReset" might help in this case if you've not tried already.
