2008-12-30 01:55:33     issue with getting Kernel information

Dear all,

 

I am using 2008R1.5 release and configured the kernel for BF561. I had done the baud rate configuration as 11520 and used to view the kernel information using the same baud rate in teraterm window.

 

While booting of uImage, i am not able to get the kernel informations like memory map details and cache information.

 

Initial part of kernel information are displayed as corrupted one and other portion are displayed properly.

 

below are information, i am getting while booting of my uimage

if i set the baud rate as 57600, i can able view the initial kernel informations like memory map and cache deatils, but the other portion the information are displayed as corrupted one. Also i cant able get root prompt for further execution of the application.

 

below are kernel information, i had got while setting the baud rate 57600

Hi Mike,

 

Thanks for the reply.

 

Actually there is no problem with these uImage, since our standalone project are working with this uImage.

 

The only problem is we cant able to see the kernel details like memory map and cache.

 

I had attached the .config files build during this uImage.

 

 

 

Regards,Senthil
