ECU Block Diagrams

The microcontrollers are on a small module that plugs into a socket on the IO boards.

The first microcontroller module will be a stm32f4 and most likely followed by a MC9S12XDP512.

STM32F429NI  http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1577/LN1806/PF255172#

Same pinout as the soon to be released STM32F756NG  http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1858/LN1902/PF260794#

There are three IO board versions. 1-2Cyl, 1-6cyl and 1-16 cyl.

This way the same IO boards are used with any microcontroller and software project.

Carrizo is just around the corner so why use the older mobile APU?

1. Is it suitable for a mobile use? (A88X is normally seen in desktop mainboards)

Some people want desktop performance and lots of IO in their laptop. This gives it to them.

2. Will Carizzo already have something built in? E.g. Kabini is already quite a SOC and has built in an A68M (or something very similar) on the APU.

Carrizo has it's own FCH. But it has limited IO and performance compared to desktop. If enough people want it we'll make a cpu module based on it.

3. How many blobs are needed? E.g.: Is the USB3 AMD's own or is it Renesas?

Check with coreboot. When given the choice between open and performance most people asked for performance.
If enough people want a totally blob free version we can use an old fam10 cpu and make a cpu module for them.

Could Renesas be persuaded to open a blob?

You can try. Blobs are sometimes used to obscure the hardware design if patents are involved. Most often it's more a psychological problem. Blobs give a little more power and control to those who have the source, this makes them feel slightly better about themselves.

I haven't heard about M.2 before

M.2 is the replacement for mini-PCIe sockets.
