This command tells RedBoot to try and load a file, using a
network connection to some host computer via the TFTP protocol.
* Is your computer "host_ipaddr" running a TFTP server?
* Does it see the request coming from the target PC?
* Is the file 'redboot.bin' present on the TFTP server?
These are the sort of "setup" considerations which you need
to take for this to function.

Hi Robby,
I'm also testing eCos in a standard PC motherboard. It works flawlessly.
What I did:
- download the floppy image of Redboot
- make a floppy
- connect a null-modem serial cable between your PC workstation and the
SBC Com1:
- boot your SBC with this floppy
- run GDB (Insight) in your workstation
- using GDB, download any compiled software with eCos to the SBC
- single step, breakpoint, run, without any problem...
There are several messages discussing those steps, check the latest
massages posted by Jose Souto :)
Regards,
Jose Luiz
