Other Parts Discussed in Thread: OMAP-L138

Now i am using the flashwriter to flash the spioflash. My dsp is c6748. i hanve modify the two files metioned on this page-processors.wiki.ti.com/.../Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138#Modifications_for_Custom_Boards. And get my .ais file by the Aisgen. Then I flash the spi0flash with the flashwriter. message it give out like this:

---------

[C674X_0] Starting OMAP-L138 SPIWriter.
Will you be writing a UBL image? (Y or y)
n
Enter the application file name (enter 'none' to skip):
D:\Users\NORMAN.ARESINTEL\workspace_v5_5\test\Debug\test1.ais
INFO: File read complete.
Doing block erase.Doing block erase.Doing block erase.Doing block erase. SPI boot preparation was successful!

----------------

i think it means i have flash the memory successfully. then i set the boot mode to spi0 mode. but there is nothing happen. please give me some advice. is there any document more detail than the url it gives . thank you.

Yes, you are right. Now you are able to write/erase the SPI flash.
So please make sure that you have flashed the proper AIS image to SPI flash.
Try to create a simple LED toggling project and convert to AIS then flash into SPI.

OK,thank you Titusrathinaraj stalin. So now i have another question. How to use AISgen to make my .ais suitable. if i use spi0,how to set the params? I use AISgen d800k008. I think may be this is why my program can't run. And my app it is a simply program to light the led on my board. And can run under the simuliation status.

In this situation, is there have any problem with the .cmd file's setting? It is like this

MEMORY
{
DSPL2ROM o = 0x00700000 l = 0x00100000 /* 1MB L2 Internal ROM */
DSPL2RAM o = 0x00800000 l = 0x00040000 /* 256kB L2 Internal RAM */

Please make sure that you have enabled the PINMUX and appropriate PSC (i.e GPIO PSC, suppose you use the LED stuff in your code) in AIS settings.

The pinmux&PSC enable work,i have done in my code. is this enough? or i still need to enable these in the AISgen.exe?

I have attached a procedural document which has the section : - " SPIWriter Utility (Flash Programmer)" Please refer to it

Yes, you can try to enable it AISgen and see if it solve the booting issue.
Can you please share your LED project and let me try it on C6748 LCDK board.

Also you can flash your code through SFH utility.

I am sorry i can't find your attachment, i think "SPIWriter Utility" mey be more powerful ,so tell me where you have attached it .

I have read the bytes out of the spiflash. And the flash address i set is MSB1,MSB0,LSB=0X00,0X00,0X00. I am sure the bytes i read out is belong to my app image,which verified that the spiflash is successful. But it still not work.
Then i give it a compare with the bytes under the debug status, i find the address of the bytes i read out in this situaion is not the _c_init00,which is equal whit "0xc0006AD0", so i think may be this is the problem?
As i mentioned above, should i to do some modify in my .cmd document? For you know ,at the point of entry-point address? To find if this is correct?

Dear Titusrathinaraj:

I attached my code in the attachment, please look.

The url you give me, i had browse it before. i want to ask if i use spi0 to flash my spiflash on c6748. Whether or not should i modify the files and rebuld it? the cgwin, i have been deploying it for a whole day, it never complete by now ,so i think the spiwriter is more convient.

Thank you Shankari G, accord to the PPT you send to me, I have boot the spi0flash successfully. very appreciate it. I want to know more about the bootloader, can you give me some suggestion?
