TMS570LS0432 BootLoad FLASH API函数调用有问题

参考TI 官方BootLoad 程序，使用HerCoGen 生产的底层程序，接受DOWNLOAD 消息时，调用函数

BLInternalFlashStartAddrCheck( g_ulTransferAddress, g_ulTransferSize ) 时， g_ulTransferAddress = 0x00020000;  g_ulTransferSize = 0x000003e8;

当debug 单步调试进入函数BLInternalFlashStartAddrCheck(uint32_t ulAddr, uint32_t ulImgSize) ，ulAddr = 0x09B56E12  ulImgSize = 0x00142000；

形参的数值发生了变化 ，很奇怪的值，不知道是什么原因造成的？

Flash API 运行在RAM中，cmd 配置如下：

–retain="*(.intvecs)"

MEMORY
{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH_API (RX) : origin=0x00000020 length=0x000014E0
FLASH0 (RX) : origin=0x00001500 length=0x0005EB00 //LS04x and RM42 Flash size is 0x60000
SRAM (RW) : origin=0x08002000 length=0x00006000 //LS04x and RM42 SRAM size is 0x8000
STACK (RW) : origin=0x08000000 length=0x00002000
}

} load = FLASH_API, run = SRAM, LOAD_START(api_load), RUN_START(api_run), SIZE(api_size)

.text > FLASH0
.const > FLASH0
.cinit > FLASH0
.pinit > FLASH0
.data > SRAM
.bss > SRAM
}

做了一个简单测试，将CMD 中FLASH API 相关删掉后，让函数运行在FLASH 中，入参带入就没什么问题，但是BootLoad 需要将Flash 函数运行在RAM中，问题一直无法解决。

Susan Yang：

能否给出详细的例程路径？我明天看看有没有这个板子做一下测试

回复 Susan Yang:

谢谢 已经解决了。 _copyAPI2RAM_ 没移植到 void _c_int00(void)中
