Hi Frederic
I'm trying to reply your experience but I always get this error:
error: '__NR_gpiosetbits' undeclared (first use in this function)
Your workaround (add #include <asm-cris/arch-v32/unistd.h> to
gpio_syscalls.h) don't work on my crisos copy
Can you send me the Makefile, sht17.c and gpio_syscall.h?
Many thanks
