TMS570LS12 bootloader 问题

Yiran, 你好

TMS570和RM4x产品是不同的，其主频不同，且TMS570为大端模式，RM4x为小端模式。你使用的例程应该是不正确的，请查收附件，重新测试。谢谢。

你好，我现在用TMS570ls3137的开发板，烧进去UART Bootloader for' Hercules TMS570LS31x MCU文档中http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=spna193&fileType=zip提到spn193的uart bootloader例程，运行bootloader后Hyper terminal出现文档中说的主菜单，5项菜单都能够执行，但是执行完菜单1（下载应用程序bin文件到开发板中）hyper ternal显示下载成功，再在键盘上输入“3”（运行应用程序），这时应用程序不能运行，而且开发板上指示MCU错误的D1灯亮起。请问是怎么回事？按照例程压缩包中的readme.txt将bootloader里面bl_config.h中应用程序起始位置改成#define APP_STATUS_ADDRESS       0x00010000并将应用程序里面的memory也进行相应的修改（起始地址改为0x00020000 ）：

MEMORY
{
VECTORS (X) : origin=0x00020000 length=0x00000020
FLASH0 (RX) : origin=0x00020020 length=0x0017FFE0
FLASH1 (RX) : origin=0x001A0000 length=0x00180000
STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0003EB00

/* USER CODE BEGIN (2) */
/* USER CODE END */
}

原来没有修改的应用程序cmd：

MEMORY
{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH0 (RX) : origin=0x00000020 length=0x0017FFE0
FLASH1 (RX) : origin=0x00180000 length=0x00180000
STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0003EB00

/* USER CODE BEGIN (2) */
/* USER CODE END */
}

/* USER CODE BEGIN (3) */
/* USER CODE END */

应用程序是两个can模块通讯，成功后点亮LED灯，程序通过仿真器下载能正常运行，但是通过bootloader下载进去能运行到bootloader的跳转到0x00020000 处，但是再运行就会出现上面所说的现象，应用程序的main函数如下：

#include "sys_common.h"

/* USER CODE BEGIN (1) */
#include "sys_common.h"
#include "can.h"
#include "het.h"
/* Include ESM header file - types, definitions and function declarations for system driver */
#include "esm.h"

#define D_SIZE 9

uint8 tx_data[D_SIZE] = {'H','E','R','C','U','L','E','S','\0'};
uint8 rx_data[D_SIZE] = {0};
uint32 error = 0;

uint32 checkPackets(uint8 *src_packet,uint8 *dst_packet,uint32 psize);
/* USER CODE END */

/** @fn void main(void)
* @brief Application main function
* @note This function is empty by default.
*
* This function is called after startup.
* The user can use this function to implement the application.
*/

/* USER CODE BEGIN (2) */
/* USER CODE END */

int main(void)
{
/* USER CODE BEGIN (3) */

/* initialize can 1 and 2 */
canInit(); /* can1 -> can2 */

/* transmit on can1 */
while(!canTransmit(canREG1, canMESSAGE_BOX1, tx_data));

/*... wait until message receive on can2 */
while(!canIsRxMessageArrived(canREG2, canMESSAGE_BOX1));
canGetData(canREG2, canMESSAGE_BOX1, rx_data); /* receive on can2 */
hetInit();

/* check received data patterns */
error = checkPackets(&tx_data[0],&rx_data[0],D_SIZE);

/* ... run forever */
while(1)
return 0;
/* USER CODE END */

return 0;
}

麻烦能帮我看下是怎么回事吗，谢谢！！
