Attached you find a patch which enables ECC for our board.
Sorry, can't decode the attachment. Could you please send it inline? Thanks.
At the moment it is pretty PPC405GPr specific, as I have no other board around to test. I have also a Yosemite and a Sequoia, but they do not seem to have a correct SPD-info.
The 440EP (Yosemite) has a DDR controller and the 440EPx (Sequoia) has a total different DDR2 controller. And both boards you mentioned are not equipped with DIMM modules and therefore don't have an SPD EEPROM.
I will submit a patch once I have our PPC440EPx board up and running.
How far are with your 440EPx porting?
What flash devices do you use on your board?
I have a 8 bit boot-eprom AMD AM29LV040B and 8,16 or 32 MB of CFI-Flash (one 16 bit-wide bank), e.g. Intel 28F028J3A
Autsch! I really don't like such braindead designs (8bit _and_ 16bit flash on one EBC). Makes software really complicated. Please don't do this on your 440EPx design. ;-)
BTW: Sorry, but I the review of your patch will take a little longer, since we are on the Embedded World fair in Nuerberg this week.
Best regards, Stefan
