Hi,
I've recently got an Ebony board (440GP) with the original bootloader
(440GP 1.18 ROM Monitor) which I would like to replace with U-boot. Is
there a way to boot an U-boot image via TFTP to replace the bootloader,
or is it possible only with using a JTAG? I've googled through the
mailing list, but most of the related hits are dated back in 2004-2005,
they say no, one have to use JTAG, but some time passed since then, and
I would like to know if there is a way for this.
Thanks in advance,
Zoltan HERPAI

Does the original ROM monitor support writing to onboard FLASH? If yes, it
should be possible.
Best regards,

It doesn't. Theoretically, you can boot Linux and use MTD on the flash
to load U-Boot. I wouldn't recommend it without a JTAG debugger around
to fix things in case they get screwed up.
