关于C6657 nor-flash boot

CCS5.5

C6657EVM

我现在需要把调试好的程序固化到芯片的nor-flash里

我用TI提供的norwriter_evmc6657l 工程

看了它提供的README.txt

NOR Writer Utility

NOR Writer is a simple utility to program a CCS format image/data file to the NOR flash.

Steps to program the NOR:

1. Be sure to set the boot mode dip switch to no boot/EMIF16 boot mode on the EVM.

2. Copy the binary file to writer\nor\evmc66xxl\bin directory, and rename it to app.bin.

3. Change the file_name and start_addr in writer\nor\evmc66xxl\bin\norwriter_input.txt if necessary. By default the NOR writer will load app.bin to DSP memory and write the data to NOR device start byte address 0, the start_addr should always be set to the start byte addess of a sector.

4. Open CCSv5 and launch the evmc66xx emulator target configuration and connect to core 0.

5. Load the program writer\nor\evmc66xxl\bin\norwriter_evm66xxl.out to CCS, be sure evmc66xxl.gel is used in CCS and DDR is intialized.

6. Open the Memory view (in CCSv5, view->Memory Browser), and view the memory address 0x80000000.

7. Load app.bin to 0x80000000:
* In CCSv5, right click mouse in memory window, select "load memory".
* Browse and select writer\nor\evmc66xxl\bin\app.bin (raw data format), click "next"
* Set the Start Address to "0x80000000", Type-size to 32-bits, leave swap unchecked, click "finish"

8. After the binary file is loaded into the memory, run the program (in CCSv5, press F8), it will start to program the NOR.

9. When programming is completed, the console will print "NOR programming completed successfully", if there
is any error, the console will show the error message.

这里的2. Copy the binary file to writer\nor\evmc66xxl\bin directory, and rename it to app.bin.这句话我不太明白，这里的binary file是指哪个文件？是指待加载的工程的.OUT文件吗？  直接将.OUT 文件强奸式地改名为 .BIN 文件吗？还是怎样？请大神指导！谢谢！

我也想问这个问题

我的理解是如果直接NOR FLASH BOOT 

binary file就是通过工具链最终转换的.dat文件？？？

是这样吗Allen Yin

回复 skysteed:

对，不能直接用编译生成的ELF文件格式，需要转换成boot table

回复 Allen35065:

Set the Start Address to "0x80000000", Type-size to 32-bits, leave swap unchecked, click "finish"

请问这句话中的 leave swap unchecked,是什么意思？

还有我将.bat文件load到0x80000000开始的地址后，然后查看0x80000000开始的地址后面的数据，发现很多数据和.bat中的数据对不上，请问这是怎么回事？

感谢大神为我解答~~

1. leave swap unchecked 是指 swap选项前的框不要勾选上；

2.可能是缺少“Load the program writer\nor\evmc66xxl\bin\nandwriter_evm66xxl.out to CCS, be sure evmc66xxl.gel is used in CCS    and DDR is intialized.”这个步骤。
