I want to run program from External NOR flash. So how can i program the external nor flash using TMS320C6747 without JTAG Interface.

Is there any documents and articles related too.

Hi Ambati,

You can program TMS320C6747 NOR flash using serial flasher utility. You can find details about how to do this at:
processors.wiki.ti.com/.../Boot_Images_for_OMAP-L137
processors.wiki.ti.com/.../Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137
Also should be useful to take a look at TMS320C6747 Bootloader section 3.1 NOR boot at:

I have OMAP-L137(EVM)

I done programming through Serial port(UART2) arranged boot switches as below.

Pin#	7	2	1	0	3
Position	ON	OFF	ON	OFF	OFF

Using Serial Boot and Flash Loading Utility ,but after reset the board it was not running program from SPI flash,i have followed below procedure.

1)First i have loaded dsp-spi-ais.bin ,ubl-spi.bin and u-boot.bin from command prompt using this commands

D:\OMAP-L137_FlashAndBootUtils_2_40\OMAP-L137_FlashAndBootUtils_2_40\OMAP-L137\GNU>sfh_OMAP-L137.exe -flash_noubl -p COM5 dsp-spi-ais.bin

D:\OMAP-L137_FlashAndBootUtils_2_40\OMAP-L137_FlashAndBootUtils_2_40\OMAP-L137\GNU>sfh_OMAP-L137.exe -flash_noubl -p COM5 ubl-spi.bin

D:\OMAP-L137_FlashAndBootUtils_2_40\OMAP-L137_FlashAndBootUtils_2_40\OMAP-L137\GNU>sfh_OMAP-L137.exe -flash_noubl -p COM5 u-boot.bin

Successfully loaded.

2)In the next step using the same above command instead of bin file loaded my application.out file

this is also successfully loaded

3)Then i changed my boot switches to SPIBOOT0.

Pin#	7	2	1	0	3
Position	OFF	ON	OFF	ON	OFF

and reboot my board.

But it is not going to run my application from SPI flash,Can you suggest me where it is wrong.
