Did you set the chipselect?
It's been a while since I tried this and some folks have made some changes. I'll try to look and see if I can see anything obvious. Unfortunately I don't have an arduino ethernet to test

No i've not  set any chipselect.

For what Board that fw is ready TO go?
It's possibile that problem come from sdhc card?
Thanks again tor your time.

By default it's set up for Arduino Ethernet (someone else tested it, though I emulated it with a specially wired sd holder)
I think your problem might be that it is looking for the program name in eeprom. It is supposed to default to app.bin, but I'm not sure that's tested.

You are trying to load a binary file right? this firmware doesn't read hex files.
This was a feature that someone wanted, but I think I'm going to revert back to a fixed filename. Your program could always rename another  program to app.bin .

Sure i try TO upload a bin file, not an hex .

I thought that this bootloader does not read filename from eprom but it is already made fixed to app.bin.
I need to  see  deep the code...

Thanks again osbock.
