器件型号：TMS320F280025C
主题中讨论的其他器件：C2000WARE

您好！

我尝试实现引导加载程序、该加载程序应支持通过 SCI 传输的 DFU。我将使用以下示例通过 SCI 传输数据并将应用程序写入闪存：

C2000Ware_4_00_00_00\driverlib\f28002x\examples\flash\flash_kernel_ex3_sci_flash_kernel

据我所知、应用程序会等待 SCI 连接和特定命令、并执行 DFU 和引导应用程序。如果我不想直接跳转到应用程序

然后、我可以使用 DFU 阻止调用"EntryAddr = sciGetFunction (SCI_BOOT_ALT1)；"

FLASH_kernel_ex3_sci_flash_kernel 的主函数：

uint32_t main(void)
{
//
// flush SCIA TX port by waiting while it is busy, driverlib.
//
//    sciaFlush();
//
// Step 1. Initialize System Control:
// Enable Peripheral Clocks
//
    Device_init();
//
// Step 2. Initialize GPIO:
//
    Device_initGPIO();

//
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
//
    DINT;

//
// init interrupt and vectorTable, driverlib.
//
    Interrupt_initModule();
    Interrupt_initVectorTable();


//
// Disable CPU interrupts and clear all CPU interrupt flags:
//
    IER = 0x0000;
    IFR = 0x0000;

   Flash_initModule(FLASH0CTRL_BASE, FLASH0ECC_BASE, 4);

    initFlashSectors();

    uint32_t EntryAddr;

//
// parameter SCI_BOOT for GPIO28,29
// refer to cpu1bootrom.h for alternate SCI Boot Pin configurations
//
    EntryAddr = sciGetFunction(SCI_BOOT_ALT1);


    return(EntryAddr);
}

现在、TI 提供了 serial_flash_programmer、地址为 C2000Ware_4_00_00_00\utilities\fel_programmers\serial_flash_programmer、它似乎也希望始终首先发送引导加载程序。

我可以通过某种方式阻止 Flasher 工具首先发送引导加载程序、然后直接发送应用程序吗？当我不使用命令"-k bootloader_hex.txt"时、我收到 serial_flash_programmer.exe 的运行时错误。提供了 serial_flash_programmer 的源代码、但我想阻止我自己重新编译它。

编辑：

我现在可以启动闪存中的引导加载程序、但当我通过 SCI 写入时、我现在会得到 CRC 错误。因此、由于某些函数未在 RAM 中运行、因此在某种程度上存在问题。对于此引导加载程序示例、我需要将什么加载到 RAM 中？

您好！

我们将其分配给了我们的闪存内核专家。她会在一天或两天内回来。

谢谢、此致、

我现在可以使用串行闪存工具成功刷写应用。我现在遇到的问题是、将引导加载程序移植到闪存中进行启动、因为此时它仅位于 RAM 内部。当 codestart 位于 0x080000 (begin)时、应用程序将只运行、并且引导加载程序可能也需要完全相同的地址。当引导加载程序已经加载到该应用程序时、我是否可以移动该地址？我认为有中断矢量地址、那么应用程序如何访问它？

我在上面的主线程中添加了两个链接器文件、您能不能帮助我如何修改 begin for both 文件以便能够从引导加载程序加载应用？

您可以为此使用 serial_flash_programr_appln.exe。此程序仅加载映像、并假定器件已运行闪存内核。您仍然需要传递-k 参数、但这实际上不会拉入内核文件进行写入。

当闪存内核在闪存中运行时、您需要确保闪存 API 被复制到 RAM 中。您可以参考闪存编程示例、以了解如何在运行时将闪存 API 复制到 RAM 中。

我在上面的主线程中添加了两个链接器文件、您能不能帮助我如何修改 begin for both 文件以便能够从引导加载程序加载应用？

[/报价]

您可以更改应用程序映射到的扇区、使其不会与闪存内核重叠。您可以将 code_start 段更改为 begin 以外的扇区。您的器件是否设置为闪存引导？如果是、如果您希望应用程序在器件复位时启动、您可能需要修改闪存内核的闪存内核链接器命令文件。
