Hello again!
I configured the eCos installation with the "i386PC target" template, put
the Startup Type to FLOPPY and
built it.
I wrote a simple hello world program, compiled it ok and then make the
i386-elf-objcopy -O binary hello hello.bin
and then:
dd conv=sync if=hello.bin of=/dev/fd0
for it to run booting from the floppy disk...
The program is a simple thread in a loop that prints out "Hello World"...
It should boot up and start printing "HelloWorld"... but it doesn't!
After booting nothing is on the screen... just the cursor blinking...
I launch the threan on the cyg_user_start... I think I am doing
everything
by the book...but it does not work.
can you help me?
Did you configure it to use the screen as it's debug I/O device?
Note that the default is to use COM1 (the first serial port) since
it is more common to have only serial connections than VGA screens
for truly embedded systems.
