I am getting Error: Timeout waiting for MCU, When I tried to flash the application program using mikro bootloader GUI. I am using PIC18F67K40 microcontroller. The below code I am using:
Code: Select all
#include "built_in.h"
#pragma orgall 0x1C000
#define BOOTLOADER_START_ADDR 0x1C000
#define START_PROGRAM_ADDR 0x1C300
static char block[64];
void Start_Program() org START_PROGRAM_ADDR{}
unsigned short UART_Write_Loop(char send, char receive){
unsigned int rslt = 0;
while(1){
Delay_5ms();
UART1_Write(send);
Delay_5ms();
rslt++;
if (rslt == 0x0200)
return 0;
if (UART1_Read() == receive)
return 1;
}
}
void Write_Begin(){
FLASH_Write(START_PROGRAM_ADDR, block);
//FLASH_Write_64(START_PROGRAM_ADDR, block);
//--- goto main
block[0] = 0x60; //0xF03EEF60
block[1] = 0xEF;
block[2] = 0x3E;
block[3] = 0xF0;
}
void Start_Bootload() {
char i = 0, xx, yy;
long j = 0;
while (1) {
if (i == 64) {
//--- If 32 words (64 bytes) recieved then write to flash
if (!j)
Write_Begin();
if (j<BOOTLOADER_START_ADDR){
FLASH_Write(j, block);
//FLASH_Write_64(j, block);
}
i = 0;
j += 0x40;
//j++;
}
//--- Ask for yy
UART1_Write('y');
while (!UART1_Data_Ready()) ;
//--- Read yy
yy = UART1_Read();
//--- Ask for xx
UART1_Write('x');
while (!UART1_Data_Ready()) ;
//--- Read xx
xx = UART1_Read();
//--- Save xxyy in block[i]
block[i++] = yy;
block[i++] = xx;
}
}
void main() org BOOTLOADER_START_ADDR {
UART1_Init(9600);
if (UART_Write_Loop('g','r')) {
Start_Bootload();
}
else {
Start_Program();
}
