STM32 F4 Discovery Demo

I've got a STM32 F4 discovery board for STM32F401with the 9 axis sensors on it. I want to open up the demo project using Keil uVision 4 and modify it. I'm getting an error as soon as I open the project that says Error: Device not found   Device: STM32F4_256KB  Vendor STMicroelectronics  Please update your device selection.

I've enclosed a screen shot of this error.I don't know what the heck that means. The board shows up in the device manager and is called STMicroelectronics STLink dongle which I think is correct. I've got version 5.1.0.0 of uVision. It is the Lite version.... actually now that I think about it maybe that's my problem. The Lite version is only good for 32K, right? There is a lot going on in this demo with the accelerometers and such. Is that what this error means? I'm not sure though, when I try starting the debugger I get an error ''Cannot Load Flash Device Description'' Any help would be appreciated.Mike #stm32-f4-discovery

So really the

then? Not sure what version of Keil supports the F401 chip, and if you have to install some other package/patch to Keil to address. In 4.71 you can just set the Target to a F405OE, truncate the memory settings to those of the F401, and select the regular 1MB flash algorithm. Make sure it has the right defines, and uses the appropriate startup/system files, and you should be fine.

The error you get specifically means it doesn't like the Device/Target selected for the project, or the Flash Algorithm picked to program it.

Thanks a lot clive1.

Yes, I do have the STM32F401C-DISCO.I went and set the target device to STM32F401VC which is what I believe is what is on the discovery board. Now I get a bunch of compiler errors every time stm32f4xx.h is included which is a lot. All the errors are 

expected a ''}''

.  in the #if defined (STM32F401xx) block. That makes me think there is some incompatible combination of #defines.Argh! I don't know why this is so hard! It's supposed to be a canned demo for this Discovery board.I will keep trying stuff in a semi random way.Mike  As an aside how do you get pictures to show up in the body of your post?

You need to make sure you only have one CPU type defined, otherwise it will try to include multiple groups of incompatible code. USE_STDPERIPH_DRIVER,STM32F401xx
