Page 5: Change Log
• added LM75 temp sensor • only one CAN bus and connector (CAN2) to overcome problem with SPI1_CS0 line - one CAN bus supported with TX1 firmware provided by Auvidea J120 Rev 4 (38198-4) • changed I2C pullup resistors from 1k to 10k (to improve I2C signal low level) J120 Rev 5 (38198-5) •... - Page 6 So the J121 makes 2 USB 3.0 ports available at the expense of the M.2 slot being reduced from 4 lanes to 2 lanes. For the J121 to be working correctly it needs our new firmware. Please visit www.auvidea.eu/ firmware/ to get the latest version.

Page 9: Getting Started
Please put the the TX1 into the upgrade mode with the recovery button before connecting the USB cable to USB0. Alternatively please perform the firmware upgrade on the TX1 development board. Firmware upgrade is supported fine on the newer revs. AUVIDEA GMBH TECHNICAL REFERENCE MANUAL... - Page 10 TX1. A typical application for this task is the GStreamer. A driver developed by Ridgerun is provided and included in the Auvidea TX1 firmware. Please contact us for the source code of the driver.

- Page 12 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. Because of a bug in the SPI_CS_0 handling only 1 CAN controller is populated.

It is available in the Auvidea online shop and at digikey.com (497-10633-ND). To connect to the J120, please remove the 2 CN3 jumpers and connect SWCLK, SWDIO and GND to the 4 pin CN2 header.
- Page 26 MCU so that it may be bypassed. Alternatively the MCU may be removed. 2. please populate RN1 with a 10 Ohm resistor network (Panasonic: EXB-24V100JX, Digikey: Y5100CT-ND, Auvidea: 25151), to connect the UART0 port of the TX1/ TX2 to J7. Please note that this requires very good soldering skills and it should be performed by our technicians.
- Page 27 Q: Why does not USB work on my J120/J121? A: You have to flash your TX2 module with Jetpack 4.2 using NVIDIA's SDK manager and then apply our patch: J120: https://www.auvidea.eu/download/firmware/TX2/v2.0/J120_4.2.zip J121: https://www.auvidea.eu/download/firmware/TX2/v2.1/J121_v2_1.tar.bz2 Instructions on how to apply it are inside the downloaded .zip file.
