Hi Folks-

FreeRTOS has a build config file (FreeRTOSConfig.h) that users can apply 
at build time to customize the RTOS.  The FreeRTOS web site has a page 
to describe the options (https://www.freertos.org/a00110.html).  What it 
doesn't have is any hints about how much RAM it might save me.

Does anybody have any first hand advice about how much RAM each option 
might contribute to the RAM footprint?  Google isn't helping me.

I'm trying prepare an STM32L151 to accommodate my as yet unwritten 
application code with FreeRTOS.  The map file is showing me that 
FreeRTOS is using 15,000 bytes of RAM.  The HAL and startup/interrupt 
codes use 2,400 bytes of RAM.  That leaves me with about 14,800 bytes 
for application code.  I would like to be prepared to reduce the 
FreeRTOS RAM footprint if I need to in the future.

I know I can elevate optimization (presently set to none) but I don't 
want to do that this early in the code-writing stage because it makes 
the debugger present better steppable code.

Thanks - JJS
