Muneendra, If you haven't already tried it, enable the debugging output for your kernel. To do this, open the .config file in the top directory of your linux source code on your host system.
Then, change # CONFIG_DEBUG_KERNEL is not set # CONFIG_DEBUG_INFO is not set # CONFIG_DEBUG_LL is not set To: CONFIG_DEBUG_KERNEL=y CONFIG_DEBUG_INFO=y CONFIG_DEBUG_LL=y You will have to recompile your kernel, but this will give you a more verbose output so that you can see exactly where it is hanging. Also, the Davinci express DSP WIKI has some helpful info: http://tiexpressdsp.com/index.php?title=FAQ_for_DaVinci_Linux Regards, Joe Young -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Friday, April 24, 2009 8:22 AM To: [email protected] Subject: Davinci-linux-open-source Digest, Vol 40, Issue 163 Send Davinci-linux-open-source mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of Davinci-linux-open-source digest..."

Does it stop after the NFS boot procedure? If you have moved to a new kernel, you might want to use the target file system associated with this kernel.

It is just uncompressing the kernel and trying to boot as shown below Starting kernel ... Uncompressing Linux....................................................................... ......................... done, booting the kernel. It stops here. I just checked the ram area where the kernel is loaded by doing md 0x8070000 and found kernel is available there.. Are there any patches to be applied for this latest 2.6.28historic davinci kernel??. which file we can look for memory map change??
