TMS320C6748 NANDFLASH BURN AND BOOT EXAMPLE

A good place to start would be with this wiki article: http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L138

Those tools might not work if you are running on a custom platform.  You can also check in the boot and flash utils package, and there are projects in there that will run under CCS using an emulator.  That might be simpler, but you would need a GEL file for your platform that would do all the low-level init (PLL setup, DDR setup, etc.).

Thanks for the prompt reply.

I built a ccs project (ccs v4.12)that include the .c and .h files referring to OMAP-L138_FlashAndBootUtils_2_36.

5481.nandflashwriter.rar

The projector can be compiled successsfully like this:

NAND boot preparation was successful!

_______________________________________________________

The C6748 runs at 456MHz, the DDR2 runs at 150MHz (top speed of the DSP's DDR controller).

My apply program is ys_c6748, the initial of the chip like this:

 

Any idea what I did wrong?

My c6748 initial like this:4784.ys_c6748_initial.rar.

The verision of rom is 006.

Below is AISGen steps.

what is the means for "CS3 Setup 0x3FFFFFFFC"?

The bootmode set:

BOOTMODE[7:0] =00001110

 

Anyone can help me ？

I need a hand!

 

do you work your problem out ?? we use same way to download the uboot and ubl , but the spi_flash writer project which provided by TI can not work ,the .out file can not prode my spi flash type on the EVM OMAPL138 board. can you help me ??

我已经解决了我的问题，烧写代码应该没有错误的。
