extension board #1

Open gkasprow opened 1 year ago

This board is for debugging only. For the moment we have to remove the backplane to debug DIOT cards. image

Does it also work for a peripheral board that only has the one connector? That's here: https://github.com/sinara-hw/DIOT_PERIPH_extender_card/

gkasprow commented 1 year ago

the peripheral boards use 2 connectors: P1 and P6 by default. image image

P1 looks similar but they differ substantially. image image

@filipswit is it worth making an assembly variant for the peripheral board? It seems that only slow signals would be affected

filipswit commented 1 year ago

Actually I was thinking about making an assembly variant. There are few differences on P1 connector: Missing GA2, GA3 (On SB they are tied to GND) Servmod (not connected) CLK (not connected) PS_ON_N and RST should be routed as a Diff (on Peripherial it is LVDS 15)

I'm not sure if we should care about P3 and P4 connectors since we don't use them for now. But on P3 and P4 connector we have Vaux[1..4] supply on differental lines. All of IOs would be routed as differential pairs, but I don't think it is an issue.

P3 and P4 pinout: image

And of course overlay will be tricky

@filipswit please make the release

Done.
