Howchip ExSOM-8895 Exynos 8895 Board is Designed for Android Development

Howchip has just launched a new Samsung based Android development kit -ExSOM-8895 DVK – powered by an Exynos 8895 system-on-module with 4GB DDR4, and UFS 2.1 storage. as well as featuring a carrier board exposing other interfaces such as mini DP, MIPI display and camera interfaces, Gigabit Ethernet, a UFS card reader, and so on.

Having a Samsung Exynos 8895 board means we get a fairly powerful development platform, as the processor is found in Samsung Galaxy S8 smartphone released last year.

ExSOM-8895 DVK specifications:

  • SOC – Samsung Exynos 8895 octa-core processor with four custom ARMv8 “Mongoose M2+” cores, four Cortex-A53 cores (max freq: 2.1GHz), and an Arm Mali-G71 GPU
  • System Memory – 4GB LPDDR4x 1866MHz (POP)
  • Storage – UFS2.1 device (default), micro SD card (SD 3.0) slot, and UFS2.1 card slot,
  • Video Output / Display I/F
    • Mini Display Port 1.2 output
    • 4-lane x 2-ch MIPI DSI connector for WQUXGA (3840×2400) displays
  • Camera – MIPI CSI 2-channel connector
  • Audio – 2-in-1 audio jack for earphone and MIC-in
  • Connectivity – Gigabit Ethernet connected via mPCIe socket
  • USB – 1x USB 3.0 port, 2x USB 2.0 ports,
  • Expansions
    • Standard Mini PCIe interface for future use(Gen2)
    • Other I/O: GPIO, I2C, SPI, UART, etc… (but where?)
  • Debugging – JTAG header; 1x USB device port for ADB and debugging; 3-pin serial debug port
  • Misc – DB9 serial port, mechanical power switch, control buttons, and boot option jumper
  • Power Supply – Via power barrel jack
  • Dimensions
    • CPU Module – 70 x 50 mm
    • Carrier board – 120 x 120mm (Nano ITX form factor)

Gigabit Ethernet is done through an mPCIe card, so you’ll have to remove GbE if you plan on making use of the mPCIe socket for other purpose. The specifications lists I/Os like GPIO, but I’m not sure where those are accessible, if at all, unless the company just means they are made available through the CPU module connectors.

ExSOM-8895 CPU module itself has six board-to-board connectors with a total of 360 pins. The company will provide Android 7.0 Nougat with Linux 4.4.13, and the source code will be provided upon delivery. The kit will also ship with a power adapter, and a serial cable for debugging.

The ExSOM-8895 module and development kit are now ready for mass production, but the company did not disclose pricing publicly, and instead ask interested party to contact them by email. The product page may have some extra information, but don’t expect much details like a Wiki or other public documentation.

I like the power switch.

I would not be surprised if this board is over $1,000. Of course I won’t be buying one.

While the board looks really cool, sadly they’re proposing a 4.4.13 kernel containing 7700 known bugs that have been fixed upstream over the last 2 years. It’s really a shame to put that crap into the hands of developers, because they will start to code on top of it until they realize the problem and that it’s too late to fix it. As long as hardware vendors will not understand the importance of following software updates, Android will continue to be the most vulnerable operating system in computer history, and it’s not because of the OS but because of those who adopt it for the low cost and refuse to accept the principle that comes with it which is that QA is very short and that bugs get fixed over a long maintenance period after the initial release. It is totally irresponsible from them to do this.

Thus it very likely is the BSP provided by Samsung which is crappy, it’s even worse!
