Hey, thought I’d ask if anyone knew what these footprints (seems like an IC and then a fairly pin-dense connector) on the bottom of the mainboard are meant for? Can’t find any reference to them in the published schematics or from my quick skim through EC firmware
Maybe an unpopulated jtag/debug connector? Also quite curious now.
If it’s debug I’d imagine it would have to be for something other than the EC, considering JECDB and JSWDB are both at the top edge of the board, nestled between JPD1, whatever that is (maybe debug for a usb pd controller?)
the pin density does make me wonder… that’s a lot more than standard jtag, unless there’s multiple interfaces on the one connector. Either way yeah I’m intrigued
Maybe they just reused a connector they were already using instead of getting a specific one, one less reel on the pick and place machine…
