Page 8: Getting Started
Console access The console port of the TX1 is UART 0. The J120 converts this UART port to standard 3.3V TTL levels. So a standard USB to TTL serial converter may be used to connect to the console. Just connect TXD, RXD and GND to the USB converter. - Page 9 CSI-2 connector The J120 features one CSI-2 connector with 4 data lanes. It is a 22 pin FPC connector with 0.5mm pitch. It has the same pin out as the 22 pin CSI-2 connector found on the carrier board for the Raspberry Pi compute module.
- Page 10 A 9 axis sensor is connected to the SPI0 bus of the TX1. Pin 8 (VddIO) of the IMU is connected to 1.8V. Please set the INT output of the IMU by software to „totem pole“ mode as there is no pull-up on the INT output. This IMU is optional. Only some J120 models are equipped with this function. Function...
- Page 11 70: -- -- -- -- -- -- -- -- The J120 features 1 or 2 CAN interfaces. As the Jetson TX1 does not have native CAN interfaces, the J120 features 2 SPI based CAN controllers (Microchip MCP2515). Please install the Kernel and support package with the MCP2515 driver, which is provided by Auvidea.
