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. {% hint style="warning" %} **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 {% endhint %} #### 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. #### Block Diagram ![](/files/kzhv2RTDKqg64clzM0xR) #### Specifications | | | | ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | | **Features** | **CN9130 SOM Specifications** | | Processor Core | 4 cores Arm Cortex A72 | | Processor speed |

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: | | | | | ---------------- | --------------------------- | ----------------------------- | | **Feature** | **A388** | **CN9130** | | USB2.0 | 3 Ports | 2 Ports | | SATA 3.0 | 3 Ports | 2 Ports | | 125MHz clock out | ✓ | X | | SD/EMMC Boot | boot from either SD or eMMC | Can boot from both SD or eMMC | | MCi interface | X | ✓ – Connector J3 | | input voltage | 5V and 3.3V | 5V | #### 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. SolidRun, recommends to not disable the frequency scaling feature. #### Power Measurments The measurements below were conducted without frequency scaling, to reflect the maximum power consumption: | | | | | ------------------------------- | ------------------------------ | ---------------------------- | | **Test** | **Power \[W]** | **Tj \[degC]** | | Idle u-boot | 4.6 | 50 | | idle Linux |

| ## 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. #### SERDES Muxing CN9130 – CP0: | | | | | | | | | ------------------------------------------ | ------------------ | -------------------- | ------------------ | ------------------ | ------------------------ | ----------------- | | **Interface** | **SERDES Lane0** | **SERDES Lane1** | **SERDES Lane2** | **SERDES Lane3** | **SERDES Lane4** | **SERDES Lane5** | | 10GBASE-R/XFI | | | ETH\_Port0 | | ETH\_Port0 | | | 5GBASE-R | | | ETH\_Port0 | | ETH\_Port0 or ETH\_Port1 | | | 10GBASE-X2 (RXAUI) | | | ETH\_Port0 Lane 0 | ETH\_Port0 Lane 1 | ETH\_Port0 Lane0 | ETH\_Port0 Lane 1 | | 1000BASE-X (SGMII) / 2.5GBASE-X (HS-SGMII) | ETH\_Port1 | ETH\_Port2 | ETH\_Port0 | ETH\_Port1 | ETH\_Port0 or ETH\_Port1 | ETH\_Port2 | | SATA 3.0 | SATA1 | SATA0 | SATA0 | SATA1 | | SATA1 | | USB 3.0 HOST | | USB 3.0 Port0 Host | USB 3.0 Port0 Host | USB 3.0 Port1 Host | USB 3.0 Port1 Host | | | USB 3.0 Device | | USB 3.0 Port0 Decive | | | USB 3.0 Port0 Decive | | | PCIe RC/EP | PCIex4 Port0 LANE0 | PCIex4 Port0 LANE1 | PCIex4 Port0 LANE2 | PCIex4 Port0 LANE3 | PCIex1 Port1 | PCIex1 Port2 | | **Assignment on Clearfog Base** | SATA0 Port 1 | USB-3.0 Host Port0 | XFI ETH Port0 | SGMII ETH Port1 | USB-3.0 Host Port 1 | PCIe Gen3 Port 2 | | **Assignment on Clearfog Pro** | SATA0 Port 1 | USB-3.0 Host Port0 | XFI ETH Port0 | SGMII ETH Port1 | PCIe Gen3 Port 1 | PCIe Gen3 Port 2 | The following port configuration can’t be used simultaneously: * SGMII port 0 / HS SGMII port0, RXAUI and XFI/10GBASE * SGMII port 1 and HS SGMII port 1 * SGMII port 2 and HS SGMII port 2 #### CORE Clock BOOT Straps * PLL\_SEL\[0] – MPP\[15] – CP\_SPI1\_MOSI * PLL\_SEL\[1] – MPP\[16] – CP\_SPI1\_SCK * PLL\_SEL\[2] – MPP\[17] – CP0\_SYS\_PLL\_SEL2 * PLL\_SEL\[3] – MPP\[46] (not exposed on B2B connector, 10K pull-down on SoM) | | | | --------------------- | --------------------------------- | | **Core Clock \[MHz]** | **Configuration PLL\_SEL \[3:0]** | | 1600 | 0x0000 (0h0) | | 2000 | 0x0010 (0h2) | | 2200 | 0x0100 (0h4) | #### BOOT MODE BOOT Straps * BOOT\_MODE\[0] – MPP18, 10K PU * BOOT\_MODE\[1] – MPP19, 10K PU * BOOT\_MODE\[2] – MPP20, 10K PD (not exposed on B2B connector) * BOOT\_MODE\[3] – MPP21, 10K PU * BOOT\_MODE\[4] – MPP22, 10K PU (not exposed on B2B connector) * BOOT\_MODE\[5] – MPP23, 10K PU (not exposed on B2B connector) | | | | --------------------------------------- | ----------------------------------- | | **BOOT MODE** | **Configuration BOOT\_MODE \[5:0]** | | SD Card (CP\_SD) | 0b101001 (0x29) | | eMMC (AP\_SD) | 0b101010 (0x2A) | | NOR Flash SPI 24 address bit (CP\_SPI1) | 0b110010 (0x32) | | SD Card (CP\_SD, undocumented) | 0b111001 (0x39) | | eMMC (AP\_SD, undocumented) | 0b111010 (0x3A) | #### CP0 MPP\[62:0] | MPP # | Pin # | Pin Description | Notes | | ------------ | ----- | -------------------- | -------------------------------------------------------------------- | | AP\_MPP\[0] | AP10 | AP\_SD\_CLK | 1.8V, serial 22ohm resistor | | AP\_MPP\[1] | AT10 | AP\_SD\_CMD | 1.8V, 10K PU | | AP\_MPP\[2] | AP16 | AP\_SD\_D\[0] | 1.8V, 10K PU | | AP\_MPP\[3] | AP18 | AP\_SD\_D\[1] | 1.8V, 10K PU | | AP\_MPP\[4] | AT16 | AP\_SD\_D\[2] | 1.8V, 10K PU | | AP\_MPP\[5] | AP14 | AP\_SD\_D\[3] | 1.8V, 10K PU | | AP\_MPP\[6] | AP12 | AP\_SD\_DS | RCLK, 10K PD | | AP\_MPP\[7] | AT14 | AP\_SD\_D\[4] | 1.8V, 10K PU | | AP\_MPP\[8] | AT12 | AP\_SD\_D\[5] | 1.8V, 10K PU | | AP\_MPP\[9] | AT18 | AP\_SD\_D\[6] | 1.8V, 10K PU | | AP\_MPP\[10] | AV18 | AP\_SD\_D\[7] | 1.8V, 10K PU | | AP\_MPP\[11] | AY18 | AP\_UA0\_TXD |

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, consultation of Marvell documentation and Errata (available under NDA) is strongly recommended.** 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.
