NVIDIA Jetson TX2开发套件C02 载板无法上电自启动

C02 board does not support Auto-Power-On function directly, it requires a few more changes to enable that:

1. Install 0 Ohm, 0402 resistor at R313
Asserts ACOK to allow Jetson TX2 or Jetson TX2 4GB to Auto-Power-On.
2. Move R501, 10k, 0402, resistor to R287
Enables the VDD_IN supply to the module connector as soon as the power is applied (disables hot-plug protection)
3. Remove R383
Disables the ON control from the pushbutton Micro-Controller
4. Remove R384
Removes the VDD_IN Bleeder resistor to keep this from consuming power during normal operation.
5. Add wire across Q47 pin 2 and 3.
Force Button Micro-Controller in Mobile PMIC Mode (allows Jetson TX2i to function as if it were in a P2597_B04 carrier
board – will boot when power is attached without button press)
