I tried to use the math-lib to calculate for example a square root, but it doesn’t work.
The result of this example which is calculated periodically inside a test task is y = 2.565…. while x is about 25.0
x = 25.0 + 0.001 * x; y = sqrt(x);
These are my linker-flags:
LINKER_FLAGS = -lm -lc -lgcc -mthumb -nostartfiles -Xlinker -o$(TARGET).elf -Xlinker -M -Xlinker -cref -lc -t -Map=$(MAP).map
I use an AT91SAM7S256 with yagarto
binutils: 2.20 gcc: 4.4.2 newlib: 1.18.0 gdb: 7.0.1 FreeRTOS V6.0.4
Does anybody have any idea how to solve this problem?
