BBB hangs at Starting Kernel

[Ratan Yadav]

Hi All ,


After doing a lot of googling , I am turning to this forum .

I am newbie in Linux and BBB , I am sure this topic might have come multiple times in this forum but unfortunately those could not resolve my issue .

I am facing problem while booting from TFTP .

My kernel is loaded but as soon as it reaches to "Starting kernel" it hangs up completely .

Details shown on terminal is as below .


U-Boot# setenv serverip 192.168.1.5
U-Boot# tftp 0x80200000 uImage-BBB
link up on port 0, speed 100, full duplex
