Hi,

I'm currently trying to program an STM32F103ZD with 284k Flash. In the beginning programming worked just fine but debugging was quiet slow. Thus, I checked the configurations and found out, that the controller has 284kB of flash memory but in the 'utilities' register the chip was set to 512kB and so I changed the settings of the memory address range to start at 0x08000000 with a size of 0x00047000.

I tried to program, it seemed to work in the first place.

Now, every time I try to program the device via JTAG interface it gives the error message ''flash timeout...'' or ''flash programming failed''. The full chip erase seems to work but nothing else.

I tried the flash loader demonstrator but doesn't even get a connection.

Is there any way I can revive the chip?

Your help is much appreciated.

Thanks.

Steve

I just checked the eva-board again and recognized, that the controller on the board is not an STM32F103ZD, but an STM32F103ZE. Hence, the controller I tried to configure got completely wrong flash informations.

Is there any way to completely reset the chip to the factory settings?

Apparently, the controller seems to have changed its mind and today it's programmable again

Problem solved. Thanks anyway.

Hi Steve,

that's what I found so times. One day a feature works and the other it don't. The whole environment I'm working with (RIDE7/GNU) seems to be not very stable up to this time.
