Hi,
I am designing custom carrier board with Jetson TX2 that should auto-start on power up.
Description on p16 “OEM PRODUCT DESIGN GUIDE. NVIDIA Jetson TX2” says:

It looks like mutually exclusive in relation to Jetson TX2.

Does it means Option 1 CHARGER_PRSNT# pin tied to ground completely enough to meet “minimum delay of 300ms” requirement or some delay circuit like described in Options 2, 3, 4 required too?

hello e3737c,

you’ll need CHARGER_PRSNT# pin tied to GND to make this function work for Jetson-TX2.
thanks
