Here is an extract of my code:
I have tried WordWrite located both in RAM and Flash.
__ramfunc void FLASH_MYWordWrite(u32 XtargetAdd, u32 Xdata)
{
// FLASH_WaitForLastTask();
// set the Word Programming bit 'WPG' in the CR0 Reg
FLASHR->CR0 |= FLASH_WPG_Mask;
// Load the destination address in AR
FLASHR->AR = XtargetAdd;
// Load DATA to be programmed in DR0
FLASHR->DR0 = Xdata;
// Set the Write Mode Start bit 'WMS' in the CR0 Reg to Start Write Operation
FLASHR->CR0 |= FLASH_WMS_Mask;
// Wait until the write operation is completed
// FLASH_WaitForLastTask();
}
unsigned char USB_Set_SerialNo( char *buf )
{
unsigned char success = 0;
long address = 0x0030064;
char tmp[20];
int i, j, pos;
long data1;
if ( (strncmp( ''Set_SerialNo'', buf, 12)) == 0 )
{
success = 1;
if ( strlen( buf ) != 20 )
return( 2 );
/* Disable the FLASH protection on Bank 0 sector 7 */
FLASH_WritePrConfig (FLASH_B0F7,DISABLE);
pos = 13;
for ( j=0; j
{
i=0;
tmp[i++] = buf[pos++];
tmp[i++] = 0;
tmp[i++] = buf[pos++];
tmp[i++] = 0;
memcpy( &data1, tmp, 4 );
FLASH_WaitForLastTask();
FLASH_MYWordWrite (address, data1) ;
FLASH_WaitForLastTask();
address +=4 ;
}
FLASH_WritePrConfig (FLASH_B0F7,ENABLE) ;
}
return( success );
}
