Devaiah et al., the current RH GCC that is available standalone (build 317) and also part of CCSv6.0.0 does not yet support automatically distributing code beyond the "64KB boundary". This is a major limitation and that's one of the reasons why we still consider this toolchain "beta". However there is an enhancement request filed against the tools (#4562633 - Linker does not distribute code in available ROM memory regions GCC linker cannot access memory >64k automatically) and the folks at RH as well as our own TI folks are currently working on having this addressed for the "GA" version of RH GCC for MSP430 which is planned to be released sometime in July. While we are at it there are also some improvements to the GDB Agent on the near-term radar screen.
Sorry for all the confusion this 64K issue caused, I just had a quick look into CCS release notes and a few other places and I could not see this officially documented as an issue (but I may have missed it).

Please, find the my project settings in CCSv6 that I am currently using: 1. Under "General" Tab -> Variant: MSP430F5438A. In "Advance Settings(Under Genaral tab)" -> Compiler Version: GNU v4.8.0(Red Hat) Linker command file: msp430f5438a.ld Runtime support library: libc.a (NOTE: Compiler generates the following error when I choose the "libc.a" file present in "/large/libc.a" -- "cannot find -l/home/devaiahchendanda/ti/ccsv6/tools/compiler/gcc_msp430_4.8.371/msp430-elf/lib/large/libc" 2. Under "GNU Compiler --> Runtime" Target MCU(-mmcu) : MSP430x Symbols : [I have defined the following 3 symbols: ] __LARGE_DATA_MODEL__ __LARGE_MEMORY_MODEL__ __MSP430F5438A__ 3. I have also tried including the PATH -- "/home/devaiahchendanda/ti/ccsv6/tools/compiler/gcc_msp430_4.8.371/msp430-elf/lib/large" in "Directories-->Include path" but this didn't help. 4. Optimization Level: None also, I have enabled "-fdata-sections" & "-ffunction-sections". 5. under "Miscellaneous" Tab I have entered "-mlarge". 6. I have not changed anything in "GNU Linker" Tab. All settings are default. SORRY, for writing a very long mail, this is with an intention to let you know if I am missing anything here.

Note that adding -mlarge means that *all* objects and libraries must be recompiled with -mlarge, you can't mix and match large and small model. ------------------------------------------------------------------------------ Time is money.
