No, this is a CPU Rev. A board at 400 Mhz.
Probably with the same DDR2 frequency.
Correct, the important clocking is the DDR2 frequency and not the CPU frequency (i.e. the PLB of 200MHz set on this board).
code has a problem here. I reported this problem a few weeks ago. AMCC is currently working on a fix for this.
Should we not backout the autocalib patches that cause the problem until a stable working solution is found?
Not sure. My hope is that AMCC find a solution quickly. They should receive the failing board this week.
And they already did send a "fix" (more a workaround) for this problem:
[PATCH v2] ppc4xx: Fix DDR2 auto calibration on Kilauea 600MHz
which you rejected. So I suggest to wait for a few days.
Victor, Adam, did you already receive my board?
We have not received your board yet. Do you have a shipping tracking number we can check?
Thanks, Adam
Best regards, Stefan
