Please RTFM, the UPM table is just half of the story.
for all of it working, I am going to run the u-boot memory test on the whole thing to see if there are any problems. Do you have any other suggestions that might make it more apparent if my memory is not correct?
Check if there are mirrored areas.
Am I right in saying that the following problem is indicative of a memory problem? When I plugged the BDI into the board in an attempt to figure out
No. Memory problems is just one of the possible explanations.
Call backtrace: C3BEC5D0 C0065DC8 C0045BBC C00360A0 C0036758 C00367D0 C004AAC0 C004AE38 C011DF84 C00026A0 C0002280 C0006B60
And what did the backtrace show?
I read in the FAQ that memory misconfigured PowerPCs tend to have floating point exceptions. I am not able to look at the memory indicated in the call backtrace without killing the board. Is there some other way to better
Why not? You can type "halt" at the BDI any time...
I am starting to be convinced that somehow to SDRAM is not initialized correctly, but past the UPM RAM words and writing the MAR and MCR, I am not sure what else has to be done to initialize it correctly. Any guidance
Read the chip manufacturer's manual again.
