Mandatory Flash Programming Functions (Called by FlashOS):

int Init (unsigned long adr, // Initialize Flash
|

unsigned long clk,

|
unsigned long fnc);
|
|
int UnInit (unsigned long fnc); // De-initialize Flash
|
|
int EraseSector (unsigned long adr); // Erase Sector Function
|
|
int ProgramPage (unsigned long adr, // Program Page Function
|
|
unsigned long sz,
|
|
unsigned char *buf);

|
|
Optional Flash Programming Functions (Called by FlashOS):
|
|
int BlankCheck (unsigned long adr, // Blank Check
|
|
unsigned long sz,
|
|
unsigned char pat);
|
|
int EraseChip (void); // Erase complete Device
|
|
unsigned long Verify (unsigned long adr, // Verify Function
|
|
unsigned long sz,

unsigned char *buf);

|
|
|
- BlanckCheck is necessary if Flash space is not mapped into CPU memory space
|
|
- Verify is necessary if Flash space is not mapped into CPU memory space
|
|
- if EraseChip is not provided than EraseSector for all sectors is called
