LX2K Honeycomb

LX2K

This is a quick reference for everything related to the Solidrun Honeycomb LX2K and related products

Hardware

The shipment from Solidrun only included the COM and carrier boards, with no bootable firmware image present. So, one will need to order:

• RAM
• Power Supply
• Case
• MicroSD card

I have personally verified the following:

• 2x Samsung 32GB DDR4 2666MHz RAM
• CORSAIR AX760 Power Supply
• NZXT H200 Mini-ITX Case
• SANDISK 4GB Micro SDHC Memory Card

Solidrun has a list of RAM they have tested here

Known Errata

Solidrun has a list of errata here. Of significant note are:

1. SPI ROM for firmware is not bootable. You must use MicroSD card
2. Fan PWM is not working and will run at max speed (e.g., LOUD!)
3. MDIO read issue, making the integrated ethernet not functional (AFAICT)
4. MicroSD is read only. So a bootable OS image on the SD card is not going to be fully functional.

Firmware

Since the system does not appear to come flashed with a known working version of firmware, you will need to use the microSD slot to boot. On the microSD card, flash with the firmware image. The image is tiny (<50M). I sloppily made a Yocto layer to build the SD card image (and bootable Linux image). It can be found at https://github.com/jonmason/meta-lx2k

Miscellaneous

If you have a 3D printer, I designed a back-plate to help make the case look a little more polished. It can be found at https://www.thingiverse.com/thing:3994271

There is a Honeycomb users mailing list, to help facilitate the spread of up-to-date information. It's at http://lists.infradead.org/mailman/listinfo/honeycomb-users

Personal ToDo

1. Run CPU benchmarks on system (via NVME drive)
2. Test 10G SFP+
3. Get Watercooler setup working
