TMS570ls0714 Bootloader CMD分区问题

Other Parts Discussed in Thread: TMS570LS0714

对TMS570ls0714的APP程序默认的CMD文件代码如下：

MEMORY
{
VECTORS (X) : origin= 0x00000000 length=0x00000020
FLASH0 (RX) : origin= 0x00000020 length=0x00BFFE0
STACKS (RW) : origin= 0x08000000 length=0x00001500
RAM (RW) : origin= 0x08001500 length=0x0002eb00

/* USER CODE BEGIN (2) */

/* USER CODE END */
}

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

/*----------------------------------------------------------------------------*/
/* Section Configuration */

SECTIONS
{
.intvecs : {} > VECTORS
.text : {} > FLASH0
.const : {} > FLASH0
.cinit : {} > FLASH0
.pinit : {} > FLASH0
.bss : {} > RAM
.data : {} > RAM
.sysmem : {} > RAM

FEE_TEXT_SECTION : {} > FLASH0
FEE_CONST_SECTION : {} > FLASH0
FEE_DATA_SECTION : {} > RAM

/* USER CODE BEGIN (4) */
/* USER CODE END */

进行Bootloader分区代码如下：

MEMORY
{
VECTORS (X) : origin= 0x00020000 length=0x00000020
FLASH1 (RX) : origin= 0x00020020 length=0x0009FFE0
STACKS (RW) : origin= 0x08000000 length=0x00001500
RAM (RW) : origin= 0x08001500 length=0x0002eb00

/* USER CODE BEGIN (2) */

/* USER CODE END */
}

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

/*----------------------------------------------------------------------------*/
/* Section Configuration */

SECTIONS
{
.intvecs : {} > VECTORS
.text : {} > FLASH1
.const : {} > FLASH1
.cinit : {} > FLASH1
.pinit : {} > FLASH1
.bss : {} > RAM
.data : {} > RAM
.sysmem : {} > RAM

FEE_TEXT_SECTION : {} > FLASH1
FEE_CONST_SECTION : {} > FLASH1
FEE_DATA_SECTION : {} > RAM

/* USER CODE BEGIN (4) */
/* USER CODE END */

只对APP程序编译后，将APP程序下载至Flash出现terminate按钮，resume一直为灰色，程序无法运行。分区未超限，请问这是什么原因？

APP程序除了设置cmd分区外，还需要进行其他设置吗？

Hi xing sun,

你要实现什么功能？

如果是实现Bootloader的话，bootloader程序的起始地址应为0x00000000，应用程序的起始地址应与bootloader工程里bl_config.h中APP_START_ADDRESS的地址保持一致。例如bootloader程序里bl_config.h中定义#define APP_START_ADDRESS 0x00020000， APP程序的CMD文件VECTORS起始地址即为0x00020000，则VECTORS (X) : origin= 0x00020000 length=0x00000020

如果你只是调试运行APP应用程序，其起始地址应为0x00000000，即APP程序的CMD文件应为：VECTORS (X) : origin= 0x00000000 length=0x00000020

你好，我现在想用Hercules TMS570LS31x的UART Bootloader下载应用程序到TMS570LS3137HDK中，根据bl_config.h中定义#define APP_START_ADDRESS 0x00020000，我把应用程序CMD文件VECTORS起始地址改为0x00020000，生成应用程序bin文件成功下载到板子中，但是应用程序好像不能正常运行，因为看不到程序运行的现象，而且一运行程序nerror引脚上的红色LED灯D1亮起，目测感觉是是存储空间分配的问题，我把bootloader 的CMD，应用程序原来的CMD和应用程序修改后的CMD贴上来，您能帮我看下吗？非常感谢！

Hi Hongke,

1. 先建立Uart_Bootloader工程，然后根据bl_config.h中定义#define APP_START_ADDRESS 0x00020000来设定应用程序CMD文件VECTORS起始地址，这一步是正确的；

2. 对于Hercules TMS570LS31x，你需要看一下对应datasheet里的Flash Memory的章节，TMS570LS31x的Flash中的BANK0，BANK1分别对应于CMD文件中的FLASH0，FLASH1。其中FLASH1的起始地址应为0x0018 0000，明显，你上面的定义的FLASH1的地址空间是有误的。

3. 你也可以在你的应用程序项目中生成的.map文件里查询你的memory的使用情况，核实一下你的memory配置是否正确。
