Push Buttons
The RTG004 contains two push buttons SW1 (SYS_RST#) and SW2 (FORCE_RECOVERY).
Force Recovery Mode
The USB OTG Port of the RTG004 can be used to reprogram the TX2/TX1 when put into force recovery
mode. To enable force USB recovery mode on the VPG003 follow the steps below:
1) Power down the system completely. The system power MUST be OFF, not in suspend or sleep mode.
2) Connect the OTG USB port to an x86 host device with Nvidia Jetpack installed.
3) Hold the Recovery button Power on the system with the Recovery button still depressed. After three (3)
seconds release the Recovery button.
4) The TX2/TX2i/TX1 will be detected on the other host system via lsusb as a new NVIDIA Target device.
5) After successfully updating the system software, power off the system. A clean power up will revert the
OTG port back into host mode.
RTC Backup Battery
The RTG004 contains a small CR1225 backup battery to feed the VBAT signal to the TX2/TX2i/TX1s RTC if
so desired. Install J4 to allow the battery to be connected to the RTC. An option to use the 3V3_AUX as
opposed to the RTC battery is available by installing the VBAT to 3V3_AUX jumper on J2.
