Qseven duo taps i.MX8X and i.MX7

Mar 11, 2019 — by Eric Brown — 208 views

Kontron’s “coming soon” Qseven-Q7AMX8X and Qseven-Q7AMX7 modules run Linux on NXP’s i.MX8X and i.MX7 with up to 64GB eMMC 5.0, up to 3x PCIe, and extended temperature support.

Kontron announced a 70 x 70mm, Qseven 2.1 form-factor Qseven-Q7AMX8X module with an up to quad-core, 1.5GHz Cortex-A35 based i.MX8X SoC. The company has also posted specs for a similarly “coming soon” Qseven 2.1 based single- or dual-core -A7 i.MX7 Qseven-Q7AMX7 module that was announced a year ago but has yet to ship. The Qseven-Q7AMX7 appears to be the world’s first i.MX7-based Qseven module.


Qseven-Q7AL

The Qseven-Q7AMX7 was announced along with a now shipping, Intel Apollo Lake based Qseven-Q7AL module as part of Kontron’s first Qseven launch. The Linux-ready Qseven-Q7AL offers up to 8GB DDR3 and up to 32GB eMMC 5.0, as well as a GbE controller, TPM 2.0, and optional Kontron Approtect security. Other I/O includes 2x SATA III, 2x USB 3.0, 4x USB 2.0, DP, LVDS, 2x MIPI-CSI, and 4x PCIe, among other interfaces. Commercial and industrial temperature versions are available.

Below, we’ll take a closer look at the new i.MX driven Qseven modules. Both products ship with a Yocto Project based Linux BSP with U-Boot.

 
Qseven-Q7AMX8X

NXP’s i.MX8X has shown up on several compute modules and SBCs in recent months including Congatec’s Qseven-based Conga-QMX8X module. Kontron’s new Qseven-Q7AMX8X supports the DualX, DualXPlus, or QuadXPlus Cortex-A35 based i.MX8X. The SoC is clocked at up to 1.2GHz according to the press release and 1.5GHz per the datasheet.

The only difference between the two dual-core models is that the Plus model has a 4-shader vs. 2-shader Vivante GPU. The i.MX8X also provides a multi-format VPU, Tensilica HiFi 4 DSP, and 266MHz Cortex-M4F MCU.

The industrial-focused Qseven-Q7AMX8X supports up to 3GB LPDDR4 plus 2GB to 64GB eMMC 5.0 for storage. The announcement suggests there’s also an onboard microSD slot, but that’s not reflected in the specs or block diagram. There’s also a GbE controller and an optional Kontron Approtect security chip.

Media I/O includes HDMI and dual-channel LVDS with dual-display support, with the option to swap either or both interfaces to DP. You also get 2x MIPI-CSI plus I2S for audio.

The Qseven-Q7AMX8X can also express single USB 3.0 and USB 2.0 OTG interfaces, as well as 5x USB 2.0. Other I/O includes 8x GPIO plus single SDIO, I2C, SPI, serial, and CAN. There’s a default of 1x PCIe, but you can expand to 3x PCIe “on selected SKUs,” which likely refers only to the quad-core model.

The module supports -40 to 85°C temperatures and offers IEC 60068-2-78 compliant humidity tolerance. The module has a 3-5.25V input and is touted for its low power consumption. It can even run on Lithium Ion batteries.

 
Qseven-Q7AMX7

The Qseven-Q7AMX7 supports both the single- and dual-core i.MX7 which is here clocked to 1GHz. NXP’s power-efficient SoC also offers dual 200MHz Cortex-M4 MCUs and a 2D ePxP graphics engine that supports up to 1080p resolution. At this point, there are no other i.MX7 Qseven modules for comparison, but other i.MX7 modules include Kontron’s 82 x 50mm, SMARC form-factor SMARC-sAMX7.

The Qseven-Q7AMX7 is available with up to 2GB DDR3, as well as a 2GB to 64GB eMMC 5.0. There’s also a GbE controller and an optional Kontron Approtect security chip.

Media I/O includes dual-channel LVDS, 2x MIPI-CSI, I2S, and HD audio. The module supports USB 2.0 OTG, 5x USB 2.0, 8x GPIO plus single SDIO, I2C, SPI, serial, and CAN interfaces. The single-core model supplies 1x PCIe and the dual-core model has 3x PCIe.

The Qseven-Q7AMX7 supports -20 to 85°C temperatures and offers IEC 60068-2-78 compliant humidity tolerance. The module has a 3-5.25V input and can run on Lithium batteries.
