Work In Progress

Hardware

  • End product: ARMv5, Atmel SAM9G25 based GARDENA smart gateway (sources)
  • For development: x86_amd64, Edimax EW-7811UN

Progress: Hardware is already on the market, nothing left to do or could be changed for that matter.

Firmware

As of 2020-08-31, linux-firmware contains firmware version 80.0, which is known to hang on the GARDENA smart gateway as long-term tests have shown (and on other machines too - Google knows). Only a cold reset resolves the problem, which is easy to do for an USB WLAN stick but very problematic (human intervention needed) on a embedded device without hardware reset capabilities for the USB device.

Therefore, all driver development and the verification is getting done with firmware version 88.2, which is not yet mainlined as of 2020-08-31, but has the mentioned problem resolved.
