Above is the output that i got over Jtag Uart. As u can see the initial message printed by the bootloader is in Little endian format.

i.e. U-Boot 1.1.3 is printed as -UoBto1 1.3.

All data that is read from memory and printed over Jtag are printed in Little endian format. I tried to debug using Insight.

Data that is printed is using printf statement. This calls vsprintf. When data is passed to printf it appears alright but when is passed to vsprintf it changes as above.

I also checked the code for vsprintf. It is correct.

Can any 1 tell me what can be the problem.
