evmOMAPL138板子使用startware的bootloader问题

是编译的哪个工程？

StarterWare目录下的bootloader

工程路径：

C:\ti\OMAPL138_StarterWare_1_10_03_03\build\armv5\cgt_ccs\omapl138\evmOMAPL138\bootloader

编译结果：我咋没看到编译信息里提到你说的函数：

spi flash copy的函数如下。你的starterware是不是用的别人改过的啊

#if defined(SPI)
static unsigned int SPIBootCopy(void)
{
BL_SPI_Header spiBootHeader;
rprcFileHeader rprcHeader;
rprcSectionHeader section;
int offset = IMAGE_OFFSET;
int sectionCount;

/* Spi Initialization */
BL_PLATFORM_SPISetup();
BL_SPI_Configure();

// check magic number and read image size from SPI header
SPI_readBytes(&spiBootHeader, &offset, sizeof(spiBootHeader));
if ((spiBootHeader.magicNum != MAGIC_NUM_SF) &&
(spiBootHeader.magicNum != MAGIC_NUM_GF))
{
UARTPuts("Invalid magic number in boot image\r\n", -1);
BootAbort();
}

// read application image header
SPI_readBytes(&rprcHeader, &offset, sizeof(rprcFileHeader));

// check magic number
if (rprcHeader.magic != RPRC_MAGIC_NUMBER)
{
UARTPuts("Invalid magic number in boot image\r\n", -1);
BootAbort();
}
else if ( 4 < rprcHeader.text_len)
{
UARTPuts("WARNING: RPRC Boot image header has larger text section than expected.\r\n", -1);
}
else if ( 4 > rprcHeader.text_len)
{
UARTPuts("ERROR: RPRC Boot image header is malformed.\r\n", -1);
BootAbort();
}

/* Get loadable section count */
SPI_readBytes(&sectionCount, &offset, 4);

/* Skip over any remaining text header */
offset += (rprcHeader.text_len - 4);

/* Read entrypoint(s) and copy sections to memory */
while (sectionCount> 0)
{
/* Read new section header */
SPI_readBytes(&section, &offset, sizeof(rprcSectionHeader));

if (section.type == RPRC_RESOURCE)
{
/* check that resource has BOOTADDR type (ignore other resources) */
SPI_readBytes(&section.type, &offset, sizeof(int));
if (section.type == RPRC_BOOTADDR)
{
if (entryPoint == 0)
entryPoint = section.addr;
else if (DspEntryPoint == 0)
DspEntryPoint = section.addr;
else
UARTPuts("Ignoring extra entrypoint in boot image\r\n", -1);
}

/* Skip the rest of the resource section */
offset += section.size - sizeof(int);
}
else
{
/* Copy section to memory */
SPI_readBytes((void *)section.addr, &offset, section.size);
--sectionCount;
}
}

return E_PASS;
}

能不能给我看下你的工程Properties里面的build->C6000 Compiler->Predefined Symbols里面都预定义了什么？？

我这边装的starterware里的工程都不能正常打开

默认配置：

自己连上仿真器通过寄存器看是不是UART boot模式，主机UART baud rate设的对不对，无非就是这些东西。

您好：请问

1.这个startware bootloader 工程就是烧写在arm rom中的bootrom 的源代码吗？如果不是拿这个工程的作用是什么？

2.该工程中的RPRC IMAGE 的magic num是0x43525052，这个跟AIS 的magic num 不一样，就是说该工程不能加载AIS 镜像？

3.看到网上资料说 bootloader包括了 RBL、UBL和u-boot ,请问这些boot函数都是通用的吗？不在乎加载的操作系统镜像是什么？请问哪里可以看这些boot函数源代码？ 

#1. 这个不是烧写在ROM中的源代码，这是一个二级boot的例子。类似于UBL之类的。它的作用仅仅是一个例子。不是必需的，也可以说不是必要的。我就几乎没看过这个工程。我也很少见别人用这个工程。它应该是结合tools目录下的ti_image和flash_writer来使用的。用ti_image打包你的应用程序成这个bootloader可识别的格式，并用flash_writer写到相应的偏移地址，这样这个bootlaoder才能从这个地址去读image，并解析它。

#2. 这个magic number应该是跟ti_image相关了。

#3. bootloader是个概念，只要是功能上是为了boot，都叫bootloader，RBL只芯片ROM里的bootloader，UBL指user bootloader，可以称之为second bootloader，之所以有UBL存在的必要，因为ROM本身不会去初始化PLL， DDR等，如果代码过大需要放到DDR上，则需要启动运行一个程序来初始化它，再搬移真正的应用代码到相应的位置运行，这个程序除了初始化，和搬代码，一般也不需要其它功能，所以俗称之为second bootloader.

当然在L138上，RBL支持AIS，可以在AIS里传配置给RBL里的初始化函数，UBL也是可以不要的了。

UBOOT则功能上更宽一些了，其主要目的是用来启动Linux，也有其它操作系统也借用UBOOT来启动，其目的不在于启动芯片这个层面了，UBOOT里支持各种接口如UART， 网口，USB等，其本身几经比普通的应用程序都要复杂而强大了。

谢谢您
