Snapdragon 820 board gains Linux BSP

Jul 9, 2018 — by Eric Brown 1,727 views

VIA has released a Yocto Project based Linux BSP for its previously Android-only SOM-9X20 module, which is sold along with a carrier board for $569. The module features a Snapdragon 820 with 4GB LPDDR4, 64GB eMMC, WiFi, BT, and GPS.

If you skipped over last October’s announcement of the “edge AI” focused SOM-9X20 module due to its lack of Linux support, you may want to give it another chance. VIA Technologies announced a Linux board support package (BSP) based on Yocto Project 2.0.3 for the module and has boosted its Android support to 8.0. VIA also announced a $569 price for the evaluation kit package, which combines the Snapdragon 820 based module with its SOMDB2 Carrier Board.

The SODIMM form factor, 82 x 45mm SOM-9X20 module builds upon Qualcomm’s Snapdragon 820 SoC, which features four Cortex-A72-like cores Kryo cores: two at 2.2GHz and two at 1.6GHz. The SoC also integrates a 624MHz Adreno 530 GPU, Hexagon 680 DSP, and 14-bit Spectra ISP.


The SOM-9X20 ships with 4GB LPDDR4 in a POP package, plus 64GB eMMC 5.1 flash. You also get the wireless features detailed in the spec list above.
