Hi Jeff,
The current configuration in U-BOOT works, and boots Linux with no problem. It will, however, not work on a virgin ADS development board. You have to change one jumper to get the CPU to use the Hardware Configuration word from Flash, and not from BCSR... (JP3 I think).
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.
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.
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.
The u-boot-0.3.0 did not use PBI mode by default. That might be an explanation for that.
