Problems with EP862 and ELDK

Problems with EP862 and ELDK

[Jeff Stevens Stevens]

Does anyone have PPCBoot and ELDK up an running on an
EP862 board?

I have PPCBoot working with SDRAM and Flash, but when
I compile it to read the environment variables from
the EEPROM, it won't boot.  Does anyone have this
working?

I can however get it to boot if I compile it to get
its environment variables from flash (it just
complains and then loads some defaults).  However,
when I TFTP ELDK over to the EP862 and "GO 00400000",
it complains.

Here is the screen dump:

What is the proper way to create the zImage for
PPCBoot (U-Boot)?

Please note that PPCBoot is a dead  project.  You  are  wasting  your
time. Please use the successor project U-Boot instead.

Works fine on many boards.

As it should. "go" is not the command used to  boot  a  Linux  kernel
image.

It's a two-step procedure.

The first step is reading the documentation,  i.  e.  especially  the
README and then the DULG - see
http://www.denx.de/twiki/bin/view/DULG/Manual

The second step is using "make uImage" in you kernel tree  (or  "make
pImage" if the new alias is still not there).


Finally, please note that this is off topic here.  Please  send  such
requests to the u-boot-users mailing list instead.

Best regards,
