TM4C1294NCPDT: SRAM Size Issue and Found Unkown Data Allocation in .map File

Part Number: TM4C1294NCPDT

Hi,

I am working with the TM4C1294 microcontroller, which has 256KB of SRAM memory. I was developing application code and got a SRAM size issue. But I am not handling that much data. then I checked the the .map file. There I found the unknown allocation of data in .bss region, and it's huge.

I could not understand this.

1. What are these startup_ccs.obj (.bss:buf$1$90$0)? 

2. Is it related to startup_ccs?

3.  Why are not these allowing me to use SRAM?

4. What should I do to solve this issue?

Please, assist me to fix this.

Thanks in advance
