LPC1788 IAP问题求助

suebillt

这套SD IAP程序可以升级一些不带中断的和串口中断的程序，但是稍微复杂一些比如SD卡FATFS和带Ucos的就不行了，调试很久无果
mian.c:

01	__asm void JMP_Boot( uint32_t address )

02

{

03	LDR SP, [R0]                ;Load new stack pointer address

04	LDR PC, [R0, #4]          ;Load new program counter address

05

}

06	void Boot( void )

07

{

08	SCB->VTOR = APP_START_SECTOR & 0x1FFFFF80;

09	JMP_Boot(APP_START_SECTOR);

}

11	int main(void)

15	lpc1788_SDRAM_Init();

16	lpc1788_Lcd_Init();

20	fs_test();

22	else              {LCD_ShowString(10,218,608,16,16,"Have not Updata APP!"); Boot();}

while(1);
