Posted on May 17, 2011 at 13:19Hi,
I have been working for a while with the Keil development board for the STM32F10x microcontrollers. I have just had some hardware manufactured but required more pins so have used a STM32F103ZC high density micro. I wrote a small test program and managed to program it initially first time. After that though it will not program or erase. I have worked out that the programming algorithm within uvision is for a 512K device. Initially i manually changed the address range within the device options. This caused a long list of errors. I then followed the instructions to write a programming algorithm and added the following code into the project:
#ifdef STM32F10x_256
struct FlashDevice const FlashDevice = {
FLASH_DRV_VERS, // Driver Version, do not modify!
''STM32F10x High-density Flash'',// Device Name (512kB/384kB/256kB)
ONCHIP, // Device Type
0x08000000, // Device Start Address
0x00040000, // Device Size in Bytes (256kB)
1024, // Programming Page Size
0, // Reserved, must be 0
0xFF, // Initial Content of Erased Memory
100, // Program Page Timeout 100 mSec
500, // Erase Sector Timeout 500 mSec
// Specify Size and Address of Sectors
0x0800, 0x000000, // Sector Size 2kB (128 Sectors)
SECTOR_END
};
#endif
I followed the instructions to build it, but now it will only load a low density device algorith, and gives an error message saying programming algorithm cannot be found.
Any light on this would be very helpful,
Thanks very much,
Charlie
