Si,

In order to burn flash on the device for boot using UART, TI provides a flash and boot utility called serial flash utility. This is part of the boot and flash utilities that can be downloaded here:

http://sourceforge.net/projects/dvflashutils/files/OMAP-L137/

In order to create a boot image you need to convert you application out file to an AIS boot file using the AIS Gen tool. The process of doing this and flashing the device has been described with an LED blinking example on the following wiki:

http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L137

Hope this answers your question. Good luck!!.

Regards,

Rahul

Si,

The links that I posted on my earlier reponse were specific to OMAPL137/C6747 devices.

If you are using C6748 devices you have downloaded the correct AISGen package. For boot examples and links to tools and utilities on C6748 refer to this wiki:

http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L138

Please ensure you use the correct ROM ID while creating your image. All details of finding the ROM ID on your device is described in the boot loader app Note for OMAPL138. You should also find this wiki useful to understand the boot process on C6748

Si,

I strongly recommend following the instructions on that wiki rather than just reading the wiki. This is a very simple example and should take more than 15 min of your time. If you download the example package distributed on the Boot images wiki, there is a precompiled SPI flash boot image in it. When you follow the instructions instructions, the wiki provides links to the serial flash wiki that describes flashing SPI flash:

For OMAPL137/C6747:

http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137

For OMAPL138/C6748:

http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138.

These wikis provide all the boot switch options as well as the options that can be used with sfh tool that may be required.

Regards,

Rahul
