It seems to go through the motions, downloading etc and when it is due to reconfigure itself, it disappears.
This is a new installation on a new laptop (previous computer worked ok).
Tried un-installing and re-installing uVision and Si8051F_uVision.exe driver.
Suggestions?
The C2D sharing should not be an issue, it's set to an output and it does not matter if this changes during programming.
I've tried a different SiLabs programmer and same issue. I don't have another PCB to try at present.
I've tried using the SiLabs programming utility and I can download, run/halt, disconnect/reconnect and re-download without issues.
There seems to me to be a uVision or uVision/driver setting issues?
Yes, it does sound like it.
As it's specific to the SiLabs kit, I'd second Erik's suggestion to post in the SiLabs forum.
Don't forget to link this thread, and to post a link here ...
Or, if you have a paid-for Keil licence, contact Keil support.
Similar behavior here, with uVision 5.26.2 and ARM MDK. When debugger starts and menus/windows rearrange, in ~ 1 case of 5-6 IDE hangs for while then silently dies. Since last week I work on a small laptop screen, I guess this bug is triggered by small screen size. Did not seen it with a large monitor.

And I don't have any 3rd party add-on in uVision. Not Silicon Labs or anything. Debugger device is ST-LINK v2.
