1. This socket can be either miniPCIe or SATA and must be configured via Newport bootloader hwconfig env variable and Ventana bootloader hwconfig env variable depending on product family
2. IMX6Q or IMX6D support SATA, the IMX6S/IMX6DL do not
3. The Performance column shows the SATA spec level and max bus I/O throughput - actual device performance varies per device
4. A different SoC on a SOM may later provide SATA support. Additionally, the eMMC Chip on the Venice SBCs can be increased to 64GB. microSD is also available.

mSATA

mSATA cards are miniPCIe form-factor (electrical and mechanical) cards that use SATA signalling on the PCIe signals and typically use flash based storage (Solid State Disk or SSD).

Newport

Many of the Gateworks Newport boards support mSATA. Because mSATA routes SATA signals to a miniPCIe socket, these boards use a software controllable mux to decide if mSATA or PCIe should be routed to a specific miniPCI socket on the board. The bootloader 'hwconfig' command (see here) is used to configure this mux at boot time because if PCI is desired, the bus is enumerated only once at boot time.

Newport boards with mSATA support:

• GW640x J10 (Center Right socket)
• GW630x J10 (Middle socket)
• GW620x J8 (Right socket)
• GW610x J6
• ​Newport product page

Notes:

• Gateworks would expect any SATA 3.0 mSATA to work.
• Only 1 miniPCIe socket supports mSATA - see the PCB silkscreen or hardware reference manual to determine which (if not specified above).
• Drives are currently available from a variety of manufactures including Toshiba, Samsung, HP, Intel, SanDisk and Dell.
• The selection between the standard PCIe interface and the mSATA interface is under software control using a digital I/O signal, which is configured by the bootloader on powerup via the 'hwconfig' env variable.
• Gateworks tests with a mSATA Crucial CT032M4SSD3 32GB SATA SSD: ​http://www.amazon.com/Crucial-mSATA-Internal-Solid-CT032M4SSD3/dp/B0082PVK8Q

The internal CN80XX / CN81XX SATA controller supports the following features:

• Compliant with Serial ATA 3.1 and AHCI revision 1.3.1.
• Supports SATA 3.0 (6.0 Gb/s - 600MB/s), SATA 2.0 (3.0GB/s - 300MB/s), or SATA 1.0 (1.5Gb/s - 150MB/s).
• 4KB native mode (4Kn) support

Ventana

Note - mSATA requires a quad-core processor on Ventana

• ​Ventana product page

Note - For configuring, jump to #VentanaSoftware

Many of the Gateworks Ventana boards support mSATA. Because mSATA routes SATA signals to a miniPCIe socket, these boards use a software controllable mux to decide if mSATA or PCIe should be routed to a specific miniPCI socket on the board. The bootloader 'hwconfig' command (see here) is used to configure this mux at boot time because if PCI is desired, the bus is enumerated only once at boot time.

Ventana boards with mSATA support (these all have Quad Core CPU loaded by default):

• GW5204 = J8 (Bottom Left socket)
• GW5224 = J8 (Bottom Left socket)
• GW5524 = J6 (Bottom Left socket)
• GW5304 = J9 (Bottom Left socket)
• GW54xx (all variants) = J11 (Bottom Left socket)

Notes:

• SATA II 3Gbps interface supports Mini-PCIe mSATA disk drive
• Gateworks would expect any SATA 3.0 mSATA to work
• Only 1 miniPCIe socket supports mSATA - see the PCB silkscreen or hardware reference manual to determine which (if not specified above)
• Drives are currently available from a variety of manufactures including Toshiba, Samsung, HP, Intel, SanDisk and Dell.
• The selection between the standard PCIe interface and the mSATA interface is under software control using the i.MX6 GPIO[2]:DIO[8] digital I/O signal, which is configured by the bootloader on powerup via the 'hwconfig' command.
• Gateworks tests with a mSATA Crucial CT032M4SSD3 32GB SATA SSD: ​http://www.amazon.com/Crucial-mSATA-Internal-Solid-CT032M4SSD3/dp/B0082PVK8Q
• Viritum VSF302XI240G-V11 has been validated with Newport, and Venice.

The internal IMX SATA controller supports the following features:

• Compliant with the following specifications:
• Serial ATA 3.0
• AHCI Revision 1.3
• AMBA 2.0 from ARM
• SATA 1.5 Gb/s and SATA 3.0 Gb/s speed.
• eSATA (external analog logic also needs to support eSATA)
• RX data buffer for recovered clock systems
• Data alignment circuitry when RX data buffer is also included
• OOB signaling detection and generation
• 8b/10b encoding/decoding
• Asynchronous signal recovery, including retry polling
• Power management features including automatic partial-to-slumber transition
• BIST loopback modes

Ventana Software

• Note - ' Please see the bootloader for configuring mSATA ventana/bootloader
• If configured correctly device will show up most likely as a device /dev/sdX in the operating system , etc (sdb,sdc,sdd,sde) (where sd stands for storage device and a is an identifier)

Laguna

Laguna has support for SATA on the GW2388 ​http://www.gateworks.com/product/item/laguna-gw2388-4-network-processor

• SATA Serial ATA 2.6 port
• The GW2388 includes a SATA factory ordering option. This option adds a Serial ATA data connector for supporting SATA 1.5Gbps Generation 1 and 3Gbps Generation 2 speeds. The SATA port is compliant with Serial ATA 2.6 and AHCI 1.1.
• Please consult the user manual for more information ​http://www.gateworks.com/product/item/laguna-gw2388-4-network-processor

Laguna Software

• If configured correctly device will show up most likely as a device /dev/sdX in the operating system , etc (sdb,sdc,sdd,sde) (where sd stands for storage device and a is an identifier)

PCIe based Storage

Various cards exist that implement a SATA interface over the PCIe bus.

Some common examples

• Solid State Disk (SSD):
  • ​Super Talent !CoreStore Plus - ASMedia Technology Inc. ASM1062 Serial ATA based (similar to mSATA but actually uses the PCIe bus signally and thus does not require mSATA support)
• PCIe to SATA adapters:
  • ​Syba 6G mPCIe 2-port - ASMedia Technology Inc. ASM1061 Serial ATA based

NVME

Gateworks can support M.2 M-Key NVME drives via the GW16148 adapter card. More information is available NVME Wiki Page

Setting up a New Disk / mSATA

This is standard Linux procedure that is widely documented.
