I just got a KEIL eval kit (MCBSTM32), and I'm having a little trouble getting started. Initially, I built the Blinky app and downloaded it into the eval board with no problems. I modified the program, and downloaded it without any problems too. Then I copied the project to a new directory to start making significant changes to it. Unfortunately, after it built with no errors or warnings, I couldn't load it into the eval board. I get a series of dialog boxes that say (in order)...
"Emulator lookup failed" + "Emu=JTAGjet;Port=USB emulator cannot be found" (with Retry and Cancel buttons).
After pressing Cancel...
"Select Communication Interface" shows up, with no available devices in the list, and pressing "Re-Scan devices" doesn't make any show up.
"Target Initialization Error" + "Cannot connect - ISigConnect::Connect() failed"
followed by...
"uVision3" + "Error:Flash Download failed - C:\Keil\ARM\Signum|SigUV3Arm.dll"
Sigh...
Going back to the original Blinky project, now that won't download to the target either. I checked *ALL* the project options between the two project and they're the same.
Now for the wierd part...
I can create a project from scratch for the part on the eval board, and it builds and downloads into the eval board just fine. The original and copied/modified Blinky projects won't though.
Anyone have any suggestions for making the Blinky project work again (besides re-installing the eval tools)...?
why don't you compare the project files of the working and the dysfunctional projects? actually, why don't you compare just about everything. There must be something wrong - maybe with the toolchain, which is worth reporting to Keil.
