Now, the question that comes to mind is:

How can a firmware upgrade fix the fact that Mai's sDRAM controller lacks an on-chip buffer?  Does it override the safety mechanism on the northbridge to make this unbuffered ram work, thereby causing potential damage to the DIMM's over prolonged operation?

Ok, I just answered my own question.  They turned-off the energy saving mechanisms inherent in the Mai chip.  How did I find this out?

I just downloaded the CVS to U-Boot then read the mailing lists and compared notes to what I knew about the Articia.

*edit due to having stuck foot in mouth*

Overall, looks like a decent project, now just need to see the Frieden Bros. re-submission into the CVS tree.  But the code they have there already is damned impressive.

Note,
here is the projects homepage

pst, I made sure the link worked first.

I still find OF a better overall solution, but to each their own.

Why are you making it seem like Hyperion are claiming all the credit, when they have said many times over what the base of their Firmware is?


I'm not blaming hyperion, I blame the fanatics that believe that PPCBoot/U-Boot is 100% hyperion's work.  I've been browsing the sources the past 15 minutes, and have to say that the Frieden bros produce some damned good code.  I'm actually impressed.

But after seeing everyone slapping Hyperion on the back, why not visit the PPCBoot homepage and thank those hard working people as well?
