Introduction

This document is intended for hardware engineers that are willing to integrate the CN9130 SOM from SolidRun ltd, into their own design.

The document provides details with regards CN9130 SOM rev 1.1.

The CN9130 SOM is pin and size compatible to the A388 SOM by SolidRun and can be used as an upgrade for the existing ClearFog Base and ClearFog Pro. 

Note: the pinout of the CN9130 and A388 are slightly different due to the MPP muxing of each SoC. please review carefully the tables below

 

Overview

CN9130 System On Module is a highly integrated SOM module based on Marvell’s CN9130 SoC.

The SoC highlights are up to 2.2GHz with 4 Cortex A72 Arm cores, DDR4 controller and 6 high speed SERDESs.

The module integrates the following features –

  1. CN9130 SoC (up to 2.2GHz).

  2.  On board 64bit DDR4 bus supporting up to 16GB at 2400MT/s without ECC

  3. Single 12V or 5V DC-input is required.

Compatibility between SOMs A388 and CN9130  

Both SOMs have exactly the same form factor and footprint

The CN9130 SOM was designed to support SolidRun’s ClearFog Base/Pro. In case of any custom design based on A388 that wants to upgrade to CN9130, any case needs to be examined individually and  review carefully the borad-to-board pinout 

In the documentation section there is an excel table with exact pinout difference 

Main differences due to SoC pinout:

Power Consumption

The following power consumption measurements were conducted on the following setup:

  1. Clearfog Pro carrier board

  2. Voltage / current measurement on v_5v0 voltage rail

  3. No mPCIe / USB / SATA / ETH cable were connected to the carrier board

  4. Temperature measurement was taken from linux using the following command
    ‘cat /sys/class/thermal/thermal_zone?/temp’

  5. Current and Voltage measured using an oscilloscope 

  6. Linux command ‘memtester 100M > /dev/null &’ ran 4 times according to core count

  7. Linux command ‘cpuburn-krait’ is ran 4 times in background. The reason cpuburn-krait was chosen is since it can generate most heat out of the cores (the core pipeline are most utilized)
     

Frequency Scaling

In order to improve power efficiency and increase temperature limits, SolidRun had enabled cpu frequency scaling.

Please refer to the patch below for more information.

https://github.com/SolidRun/cn913x_build/commit/5fe77346371a230fd2468bfb11cbcc2c1ea10345

SolidRun, recommends to not disable the frequency scaling feature.

CN9130 SOM extensions 

The CN9130 has two extension busses of  high performance, low latency and low power Marvell® MoChi interfaces (MCi). Each bus is comprised of 4x high speed differential pairs and a dedicated LVDS clock. Both busses are exposed through the SOM connector,  enabling to connect 1 or 2 additional 88F8215 comprising the kits of CN9131 and CN9132 on the carrier board and extending the SERDES count from 6 to 12 or 18.

Heatsink

SolidRun provides few types of heatsinks:

  1. Cool-plate: flattens the surface of the SOM, making it easier for integration  in any enclosure design

  2. Evaluation heatsink: add-on for the cool-plate, with short ribs, enabling to mount a 40mmX40mm fan. This heatsink is to be used in open frame systems, to enable developers to work with the CN9130 SOM during bring-up and software development

 

Precision Time Protocol (PTP)

Note: Information on PTP is based on SoM schematics and SoC datasheet analysis, but actual functionality has not been tested. For authoritative information, consult Marvell documentation and Errata (available under NDA).

CN9130 SoC has hardware support for PTP* and Synchronous Ethernet*.

There are three related electrical signals:

  1. PTP_PULSE (IN/OUT): Pulse per second.
    Muxable to J1-57 (MPP[28])

  2. PTP_CLK (IN/OUT) @ J1-18 (MPP[29]), J2-73 (MPP): Discrete trigger using Generate function.
    Muxable to J1-18 (MPP[29]), J2-73 (MPP[39])

  3. PTP_PCLK_OUT (OUT): Recovered clock output.
    Muxable to J1-22 (MPP[30])

PTP_PULSE and PTP_CLK can each synchronise between master and slave, the former generating periodic pulses while the latter depends on external events such as Update and Generate.

The PTP reference clock is generated internally.

PCLK_OUT provides the recovered clock, generated from a serdes lane according to its configuration registers.

Enable PTP on Clearfog Base / Pro

Note: Information on PTP is based on SoM schematics and SoC datasheet analysis, but actual functionality has not been tested. For authoritative information, consult Marvell documentation and Errata (available under NDA).

Clearfog Base / Pro support the mentioned PTP signals on the mikroBus connector:

  • PTP_PULSE: U14-2 / U3-2 “RST”

  • PTP_CLK: U14-9 / U3-9 “PWM”

  • PTP_PCLK_OUT: U14-10 / U3-10 “INT”

By default these are acting as GPIOs, apply the device-tree changes below to select PTP:

PTP is supported by the CN9130 Linux Etherent Controller Driver “MVPP2”, ensure to enable it’s kernel config option CONFIG_MVPP2_PTP: https://github.com/torvalds/linux/blob/master/drivers/net/ethernet/marvell/Kconfig#L97
