Dear Parimala Baggiri,

In my case RAM-based copy of u-boot is mapped to 0x80E80000(CONFIG_SYS_TEXT_BASE), which is not the upper RAM location. Is upper RAM means the last few megabytes of the total capacity?
Yes, upper RAM means the top end of the existing, usable RAM address range.
Any chance that you are using an older and/or out-of-tree version of U-Boot? We can only help you with mainline code...
In my standalone application, some debugging messages(printfs) are added, which are not printing in one function and even the application is not terminating for any reason. Hence, suspecting the stack size.
Attach a debugger?
Here are my processor details, Panda board ES which uses OMAP4460 processor, 4GB SDRAM, starts at 0x80000000.
4 GB RAM is special, as mapping the whole RAM would consume the whole 32 bit address space. What is the exact version of U-Boot (git commit ID) you are running? And which exact board configuration?
BTW - did you read the related FAQs?
Best regards,
Wolfgang Denk
