Production version of CC3200 will have 256Kbyte of RAM.16KB is shared with bootloader.
CC3200 does not have the user application flash memory so that we need to use internal RAM for code memory and share the 256KB RAM
SRAM size of 240KB for CC3200 ES 1.33 device
On CC3200 the code is always loaded from the serial flash into SRAM by bootloader and then executed in SRAM
Your program ( code + stack size + dynamic memory needed ) should be within 240 KB (lower 16 KB is used by CC3200 boot-loader)
If you want to use the the lower 16 KB also, please refer to section "6.1.2 Boot Loader / User Application – Sharing MCU RAM " in CC3200-Programmers_Guide.pdf and 'camera_application' from the SDK
The code can't be run from sFlash directly, CC3200 boot-loader loads the application in full from sFlash to SRAM before executing.
