Any body knows of a good tutorial on using the GNU blackfin toolchain with eclipse on Windows?
I'm trying to start with developing bare metal application on blackfin and I've installed the toolchain and eclipse C/C++ Juno but I'm unable to compile. Currently I'm getting the make: *** No rule to make target 'all' error but there are many other things I find myself lost at.
Many thanks in advance,
Hasan.
Edit: I've read a bit about the "make" programme, and decided to start a single-file test project to learn the command line toolchain (without the eclipse environment). Here is my main.c and associated makeFile:
//main.c
#include <stdio.h>
int main(void)
{
volatile int x = 42;
printf("%i\n", x);
return 0;
}
#makeFile
CPU = bf533-any
CROSS_COMPILE = bfin-elf-
CC = $(CROSS_COMPILE)gcc
LD = $(CROSS_COMPILE)gcc
CFLAGS = -c -Wall
bfin_test: main.o
$(LD) main.o -mcpu=$(CPU) -o $@
main.o: main.c
$(CC) $(CFLAGS) main.c -mcpu=$(CPU) -o $@
Here is the result of running the make command on the cmd console:

This produced the .o and (supposedly) the elf file. And here is the result of trying to run the elf file using the toolchain simulator:
D:\work\experiments\bfin_test_project>bfin-elf-run bfin_test
program stopped with signal 11 (Segmentation fault).
According to http://docs.blackfin.uclinux.org/doku.php?id=toolchain:sim, this should be running the simulator in the virtual mode. (Not sure if I should be providing other files)
Also I'm not sure if the output file (bfin_test) is actually an elf file or if it can be run using the simulator (bfin-elf-run). But if so, I'm wondering why am I getting a segmentation fault of such a seemingly simple programme. Any idea anybody? Note that I get the same error when changing main to contain only "return 0;".
Could someone please tell me where I'm going wrong.
Thanks again,
