How to call library functions LBDP-bootloader

LBDP-bootloader main functions are as follows:

1. Codes and check functions.

2. Functions Function library (including flash erase and program functions).

 

Library functions described in lbdp.h

#define LBDP_FUNC_ENTRY 0x8002B80

typedef void (*p_lbdp_remap)(void);

typedef void (*p_lbdp_writeFlash)(uint16_t addr,uint16_t writeFlashData);

typedef void (*p_lbdp_eraseFlash)(uint8_t page);

 

Main.c application needs in the following statement:

#include "lbdp.h"

p_lbdp_eraseFlash ex_lbdp_eraseFlash;

p_lbdp_writeFlash ex_lbdp_writeFlash;

//p_lbdp_remap ex_lbdp_remap;

 

ex_lbdp_eraseFlash = (p_lbdp_eraseFlash)lbdp_map(2);

ex_lbdp_writeFlash = (p_lbdp_writeFlash)lbdp_map(3);

 

lbdp_map (int index) to achieve is very simple:

lbdp_map uint32_t (int index)
{
return * (uint32_t *) (* index + LBDP_FUNC_ENTRY. 4); // this embodiment, the library function entry LBDP_FUNC_ENTRY defined in the flash.
}
