1. ) I've typed the fastboot in u-boot prompt but there is error message        

                      U-Boot# fastboot
                      Unknown command 'fastboot' - try 'help'

                  But i guess we can configure in u-boot source file to work the fastboot. if it can what is procedure or what is the patch to do?

Not sure which sources you are using here.

Fastboot support was added recently in the latest branch on the u-boot tree :

https://gitorious.org/rowboat/u-boot/commits/am335x-v2013.01.01

However, I am not sure about BeagleBone Black eMMC support in the current version. You may have to make some changes in the sources.

Hello Vishveswar

                    I got the u-boot from your link and i can get fastboot support in my beaglebone white board. but using the same code i cant enter into beaglebone black board.

                    How to add the fastboot support in beaglebone  black? what are files need to change ? 

Hello 

          How the Fastboot protocol initiate in u-boot. ist read the USB details from the board then it will initiate fastboot function? Because for same code Beaglebone white got fastboot function initiated, but fastboot not working in beaglebone black.

          I need to configure fastboot in beaglebone black. 

Please verify that you are indeed booting with the MLO/u-boot on the mmc card and not from eMMC.

Press switch S2 while powering on the Beaglebone Black. You should be able to see the u-boot information in the serial console:

I2C:   ready

I have just found that the current rowboat u-boot tree (2013.01.01) supports only sdcard  (mmc0) flashing using fastboot.

We shall update when BBB eMMC support is available.

Thanks Mr.Vishveshwar

          When will we have update for eMMC fastboot fashing for BBB ?

Is there any estimated time?

Hello 

             This link http://processors.wiki.ti.com/index.php/AM335x_Android_eMMC_booting Explain the procedure for fastboot for eMMC from u-boot. But that u-boot source is not support the Beaglebone Black because of 1GHz speed i think so. 

            Is there any way to modify that source code to Beaglebone black or TI planning  to update this issue? 

Kindly let us know the status.

Thanks,

Hello Vishveswar

Hello Pankaj Bharadiya

               Thanks for your alert. I'll try this with my Beaglebone black.

Sir, there is a typo in your git command line:

$ git clone git://gitorious.org/rowboat/u-boot.git -b am335x-v2013.01.01
