Can somebody confirm that the latest u-boot-0.4.0 with default settings on all
jumpers except for JP3 works correctly. I just downloaded the latest code
from CVS and it is not working for me.
Incidentally, u-boot-0.3.0 works on the board with the default jumper settings
(including JP3 on 2-3 BCSR) and no code changes right out of the box.
Also, does anybody have a BDI2000 config file for the MPC8266ADS that matches
the new configuration from u-boot-0.4.0?

We also had some trouble getting this board up and running with u-boot-0.4.0.
For our
case just the PBI (Page Based Interleave) SDRAM settings were not correct, since
the u-boot was only capable of handling DIMMS with four banks.
We changed the following line in board/mpc8266ads/mpc8266ads.c to get it to
work:
sdam = cols - 6;
to
sdam = cols + banks - 8;
But unfortunately this is up to now unconfirmed.

The u-boot-0.3.0 did not use PBI mode by default. That might be an explanation
for that.

Please make sure to use the revision tagged LABEL_2003_09_13_2100 or
a later revision. This will include Rune Torgersen patch to make the
default memory option on MPC8266ADS to NOT be Page Based Interleave
which doesn't seem to work with the standard 16MB DIMM.
Best regards,
Wolfgang Denk

I should have said, the latest u-boot-0.4.x. I did a cvs checkout last night
which shows me the LABEL_2003_09_13_2100 for mpc8266ads.c. And I confirmed
that mpc8266ads.c does indeed have the PBI turned off.

0.4.0 ist not the latest U-Boot-0_4_x either; the latest is
U-Boot-0_4_8

I think animal testing is a terrible idea; they get all nervous and
give the wrong answers.

Make sure you burn the flash image for U-Boot at the very start of flash (no
matter where that is). If you program it with the jumper in the default
position, start programming at 0xff800000. This will place the image
correctly. (New HRCW _must_ be at very start of memory)

Will verify latest later today.
