My questions are:
1. Why message: "...hello.bin": not in executable format: File format not
recognized." turn up?
gdb wants the elf file, not the binary you produced.
Ok, finally I use the hello.out, which is the elf file (I guess so...)
I successfully load it using gdb (and tsim eval version, I haven't use the
real target). Eventhoght it can be loaded, but tsim refuse to run it. Here
is the message:

1. Why this tsim said: "Program received signal SIGILL, Illegal instruction"
2. How to create 'the executable file'? I was successfully created ecos
bootable disk (run in PC, showing hello ecos). I enter command (in cygwin
environment):
[cygwin-agus]$ dd conv=sync if=hello.bin of=/dev/fd0
What should I do to produce the same executable (or bootable <?>)
file?
How do you intend to get the image onto the system? Does it have a
floppy and a BIOS to boot it? Are you going to burn it into an EEPROM?
Do you have a JTAG interface to load the program into RAM?
If I successfully run this 'hello.out' file, the next step I plan to load
ogg-vorbis decoder into Altera Stratix FPGA board. I don't know yet where I
will put the image (?) into this board (wether into SRAM or EEPROM or
something else). This ogg-vorbis decoder will run under eCos (and LEON
implemented on this board).
Thank you, Andrew
