I've noticed one thing in swps051k: the 8.1.2.3 "Device Naming
Convention" chapter states that there can be a part number with
"Device Speed" "0" which means "Nominal speed grade (Max MPU OPP =
OPP_NOM)" instead of "High speed grade (Max MPU OPP = OPP_HIGH)".
OPP_NOM is 1GHz and OPP_HIGH is 1.5GHz, this effectively means some
OMAP5s don't support 1.5GHz.

I remember that we already discussed this a while ago.

Which part number do we have?

Hm. Very good question!

Here is a photo of the chip we have got in the newest production run:

Maybe we can read the speed from it?

BTW, here you can see the battery of decoupling capacitors around the OMAP. There are much less,

but you also see that there are signal traces directly near them so adding more of them

becomes difficult. And doing it exactly as recommended (individual VIAs for every capacitor)

is impossible. The 3 copper layers below the surface layer are for connecting the DRAM chips

and there are also constraints how to route them. So we mix two set of design rules in this

area.

The OMAP5430 would have made life much easier in this aspect - but buying RAM chips for it

would have been a nightmare.
