Hi All,

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 u-boot stuck at “Starting Kernel” message, there after no messages in u-boot prompt.

I followed below steps.

  1. tftp 0x80007fc0 uImage
    2)tftp 0x80F80000 am335x-boneblack.dtb
  2. bootm 0x80007fc0 - 0x80F80000.

After step 3, u-boot stuck with below message.

HI Robert,

One more thing, I did printenv and checked the loadaddress ( there are 3 addresses kloadaddr, loadaddr and rdaddr which one should I consider ) and device tree address, which address I should consider( you mentioned address or my addresses which I see in printenv)?. can you please see below log which I have highlighted in red color.
