LPC1788的IAP问题

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:

[mw_shl_code=c,true]__asm void JMP_Boot( uint32_t address ) { LDR SP, [R0] ;Load new stack pointer address LDR PC, [R0, #4] ;Load new program counter address } void Boot( void ) { SCB->VTOR = APP_START_SECTOR & 0x1FFFFF80; JMP_Boot(APP_START_SECTOR); } int main(void) { CLKPWR_ConfigPPWR(CLKPWR_PCONP_PCGPIO, ENABLE); lpc1788_Uart_Init(0); printf("uart0 init success!\n\r"); lpc1788_SDRAM_Init(); lpc1788_Lcd_Init(); LCD_test(); SysTick_Init(); exfuns_init(); fs_test(); if(updata_num==1) {LCD_ShowString(10,218,608,16,16,"Updata APP SUECCED!");updata_num=0;Boot();} else {LCD_ShowString(10,218,608,16,16,"Have not Updata APP!"); Boot();} while(1); } [/mw_shl_code]

SD 卡升级部分：

[mw_shl_code=c,true]void fs_test(void) { FRESULT ceshi; char folder[255] = ""; uint32_t addr,ii; uint32_t u32Status; ceshi = (FRESULT)SD_Init() if(ceshi == FALSE) { printf("sd init error.\n\r"); LCD_ShowString(10,26,200,16,16,"Has no SD found!"); } else { LCD_ShowString(10,26,608,16,16,"Press any key to updata system in 3S:"); // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"10S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"09S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"08S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"07S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"06S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"05S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} // LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"04S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"03S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"02S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"01S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} LCD_FillRectangle (LCD_PANEL_UPPER, 320,352,26,74, WHITE);LCD_ShowString(320,26,200,16,16,"00S");Delay(1000);if(flag==1){flag=0;goto updata_APP;} SysTick->CTRL=0;// return; updata_APP: updata_num=1; SystemCoreClockUpdate(); LCD_ShowString(10,42,200,16,16,"Updata APP:");LCD_FillRectangle (LCD_PANEL_UPPER,176,376,42,58,skyblue); ceshi = f_mount(&fs,"0:", 1); if(ceshi != FR_OK){printf("f_mount error = %d\n\r",ceshi);} ceshi=f_open (&file, "UNIGBK.BIN", FA_READ); RES_FALT(ceshi); SIZE_UNIGBK=file.fsize; printf("\n UNIGBK.BIN ?????ù???ó????%d×??? \n",file.fsize); ceshi=f_read(&file, UNIGBK, SIZE_UNIGBK, &br); RES_FALT(ceshi); printf("\nbr ??????%d\n",br);printf("\n"); f_close(&file);br=0; LCD_FillRectangle (LCD_PANEL_UPPER,176,186,42,58,NavyBlue); scan_files(folder); //±é?úSD?¨????
