Q: What is the current draw limit on the 1.2V, 1.8V, and 12V power rails on header Z1?
A: 12V @ 2.0 A & 3.3V @ 1.0 A are available for an add-on card.
Q: What frequency is available on the system clock pins on header Z1?
A: There is a 100 MHz PCIe reference clock available for an add-on card. Any other clocks would have to be derived from this.
Q: What is the idle power consumption?
A: 5 – 10W idle power consumption.
Q: Does the platform require a fan?
A: A fan is included in addition to the heat sink. Fan is recommended, but depending on application may be omitted.
Q: What is the bandwidth limit of the PCIe Gen2 x4 connection?
A: The PCIe bandwidth limit is 2 GB/s.
Q: Do you have a breakout board with a standard PCIe connector?
A: The breakout board has a mini PCIe card slot, with the exception of UIM support as is done on the Jetson board. This is different from a PCIe edge connector, but is still a standard form factor of PCISIG.
Q: Is it possible to modify the bootloader on the TK1-SOM?
A: It is possible to modify the bootloader on the TK1-SOM. We use UBoot for the bootloader, and can provide the source code if needed. Our UBoot program is slightly different from the default bootloader provided by NVIDIA. These differences include mapping to different peripherals and memory components from the Jetson TK1 board. The specific guide we followed for customizing the bootloader is the NVIDIA document entitled “Platform Adaption for the Tegra Linux Driver Package.” Please refer to this guide if you will be developing your own bootloader.
Q: Is the bootloader on the board locked down, or can we replace it? We want to run our system in HYP mode; the default boot process from NVIDIA turns this off.
A: You can replace the default bootloader; we modified the NVIDIA-provided uboot program developed for the Jetson TK1 board in order to work with the TK1-SOM. You may download this and modify it to your own needs. Virtualization is supported on the Cortex–A15.
Q: What add-on boards do you support for the TK1 SOM and when will those boards become available?
A: Currently a Gen2x4 PCIe breakout board is in development; it should be available in Q1 2016.
Q: How much power are the GPU, CPU, and DRAM using?
A: GPU max power: 5 watts; CPUs max power: 15 watts; DDR3 max power: 5 watts (2 GB); 10 watts (4 GB)
Q: Do you supply a WiFi attachment module and Linux drivers?
A: USB WiFi modules can be connected to the TK1-SOM, and mini-PCIE WiFi modules can be connected to the PCIe breakout board. Linux drivers should be available from the WiFi module manufacturer.
Q: Does CEI provide customization?
A: Yes! Email email@example.com for more information.
Q: What is the temperature range for this board?
A: Operating: -20 to 55 degrees Celsius; Storage: -40 to 75 degrees Celsius
Q: Do I need to buy any other boards to make an embedded device?
A: The Power Supply Unit and the SOM boards make a complete Ubuntu system. All other boards are optional.
Q: Can I run Android on the TK1-SOM?
A: The Jedroid operating system is an open source Android OS for the Jetson TK1 board. We have not been able to get Android running on the TK1-SOM, but it does run on the Jetson, so with some modification it should be possible.
Q: Does the product come with Linux4Tegra pre-installed? If so: do you happen to know which version?
A: The latest version (as of 11/18/15), L4T 21.4, comes pre-installed on the TK1-SOM.
Q: What is the process for flashing the eMMC? Does it use the microUSB port in the same way as a Jetson TK1 board?
A: The process is the same as flashing the Jetson TK1 Board via the microUSB; however, the files have changed to suit the TK1-SOM Board.
