Hi Pooja,

I see you are missing some syscalls.
On SPC58 projects, those low-level functions are not provided automatically, so the linker complains.
One way to solve your issue is to provide those functions, defining them manually.

I suggest you take a look to these 2 AutoDevKit examples to understand how:
"SPC58ECxx_RLA SERIAL Test Application for DiscoveryPlus"  (where everything works fine)
or

"SPC58EC - AEK_POW_BMSWTX_SOC_Est_SingleAccess_CHAIN application for discovery "  
(where stdio.h and string.h have been included and *sbrk(size_t incr) has been defined)
