#177660 - C8051F120 Flash ScratchPad access |
I am trying to write a 4 byte value to the Flash scratch pad area and read it back. But it does not seem to happen. I am using the "F120_Flash Primitives.c" downloaded from SiLabs site. It has the following functions :
Flash_ByteWrite( FLADDR addr, char byte, bit SFLE) char Flash_ByteRead ( FLADDR addr, bit SFLE) Flash_PageErase( FLADDR addr, bit SFLE) I am using the flash address of 0x000A and for erase I am using the address 0x0400 as per the data sheet to erase both the 128 sectors of flash. I am using the following functions of mine : //====================== void StoreOffTime (void ) { char i; for ( i=0 ; i<4 ;i++) { FLASH_ByteWrite ( OffTimeAddr, OffDigit[i], 1); ++OffTimeAddr; } } //====================== void ReadOffTime (void) { char i; for ( i=0; i<4 ; i++) { OffDigit[i] = FLASH_ByteRead (OffTimeAddr,1); ++OffTimeAddr; } } //====================== But the Write or Read does not seem to happen as I get only zeros after the read. And I am not sure if there is any way to know if the Flash Write or Read was successful? Whats wrong and where ? Thanks Raghu |
