What could be the issue and please suggest ways to debug this. I have a AM1808 Rev A EVM of logicpd and using SDK 5.02 - latest drop from ti.com.

    Sanket,

    Please try removing the @0xc4000000 from your bootargs.  In my testing having this option causes the boot to fail while removing it causes the boot to succeed.  I have filed an issue to have this resolved in a future release.  So your bootargs should look like:

     

    setenv bootargs console=ttyS2,115200n8 rw noinitrd mem=64M root=/dev/nfs nfsroot=130.0.125.144:/home/sanket/ti-sdk-am180x-evm-05.02.00.00/targetNFS,nolock,rsize=1024,wsize=1024 ip=130.0.3.165:130.0.125.144:130.0.125.144:255.255.0.0:sanket::off

    Hi Sanket ,

    Looks like  linux is booting, the only problem is that the message is not being printed on the console, In the bootargs make ttyS2 to ttyS1
