SECTION 4 Features
4.1 Booting via SSD
Auvidea ships some development systems with a pre-configured SSD. This contains a bootable
partition which can be larger than the storage capacity of the integrated eMMC flash memory on the
compute module. This allows the installation of all tools and supporting applications in the boot
partition:

Linux

Jetpack 4.x

A large selection of SDKs like listed in appendix D (CUDA, VisionWorks, DeepStream and
more)

3rd party applications and demo programs

Sample video files to immediately try out the AI models
The SSD typically included is a 128GB NVME SSD by Transcend (model: TS128GMTE110S). It offers
very high performance as it connects to the compute module with 4 PCIe Gen2 lanes (5 Gbit/s).
Installation:
Full length 2280 SSDs must be inserted carefully as the SO-DIMM socket of the compute module
blocks tilting. Please slide the SSD in carefully from the side and ensure, that it is seated properly
before applying power. Secure the SSD with a M3 (nylon) screw. Metal screws must be treated with
care, so that the head of the screw is small enough that it does not touch any traces or components
on the compute module
High power SSDs may require extra cooling by installing a thermal pad between the SSD and the
compute module or the carrier board.
4.2 Crypto chip
The crypto chip has been added to support software licensing and copy protection. Please check the
data sheet of the manufacturer for details.
Model: ATSHA204A-MAHCZ-T

4.3 MCU
A MCU for additional power management and watchdog functions is optional. It is standard on some of the
extended versions of the JNX30. The MCU can provide features like:

Powering control (up and down) of the compute module

Brown out protection

Clean boot after short power interruptions

Watchdog support: it can connect to the debug console of the compute module

Remote power cycle via LTE (requires LTE module with UART interface – like SIMCOM
modules)
