Samsung SNDS eval board with Samsung KS32C5000 uController.

I configured eCos with the tcl script for arm/pidBE/ram.

I've modified some of the pid platform stuff having to do with the

touched.

Heres what a "make tests" did to compile the acos.c test file (FYI
arm-elf-gcc is gcc 2.25.1):

arm-elf-gcc  
 -c  
 -I/home/grante/ecos/ecos/packages/ecos-snds/install/include 
 -I.

 -Wall 
 -Wpointer-arith 
 -Wstrict-prototypes 
 -Winline 
 -Wundef
