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 interrupt controlelr, timers, UARTs etc. None of the makefiles were touched. > Which core? ARM7TDMI.

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. -I/home/grante/ecos/ecos/packages/ecos-snds/../language/c/libm/current/tests -mcpu=arm7tdmi -mbig-endian -Wall -Wpointer-arith -Wstrict-prototypes -Winline -Wundef -ffunction-sections -fdata-sections -g -O2 -Wp,-MD,vectors/libm_acos.tmp -o vectors/libm_acos.o /home/grante/ecos/ecos/packages/ecos-snds/../language/c/libm/current/tests/vectors/acos.c
