No, not from me while porting to Canyonlands. Could be that AMCC tested it on their 460EX Maple reference design. Please contact AMCC on this. As you already noticed, cpu/ppc4xx/cp44x_spd_ddr2.c has some DDR1 support. But I'm not sure if this will work "right out of the box". Could be that some changes are needed. > Another question is - are there DDR1 DIMMs that can be used on > Canyonlands ? No. This is not possible.
