[beagleboard] BBB booting with own compiled uboot

[Pon Senthil Rajan Jeyaraman]

Hello All,

I have purchased a beagleone black board which comes with a debian OS in 
the eMMC, I want to replace the existing debian OS in the eMMC with my own 
compiled uboot and need to load the kernel image from the TFTP protocol.

For the above setup I'm struck with the below questions;
1. where could I get the uboot source for eMMC?
2. How to replace the existing eMMC image with my new compiled uboot image 
and boot the hardware with my uboot?

Could some one kindly provide your help.

Thanks and Regards.

[beagleboard] Support: Uboot TFTP Configuration in BBB

[Pon Senthil Rajan Jeyaraman]

Hello All,

I'm trying to configure network and TFTP in the uboot of eMMC of BBB with 
the below uboot commands.

setenv autoload no
dhcp
setenv netmask 255.255.255.0
setenv dnsip 192.168.0.1  
setenv gatewayip 192.168.0.1
setenv ipaddr 192.168.0.120 
setenv serverip 192.168.0.6 - (my PC address)
saveenv

after saving the above environmental variables, Tried the below steps to 
ensure the connection between BBB and my PC.
1. ping from my PC (192.168.0.6) to BBB - destination is not reachable.
2. TFTP also ends with result - "ERROR: The remote end did not respond in 
time."

why I'm not able to ping to the configured ipaddress of BBB, and I'm also 
not able to see the BBB entry in my router active list.

I have already worked with tftp in other boards in past, but for BBB not 
sure what i'm missing.
Could any one provide a suggestion.

Thanks.
