Work In Progress
rtl8xxxu on RTL8188CUS on GARDENA smart gateway
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.
Progress
Upstreaming FW 88.2
Currently, FW version 80.0 from vendor driver rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404 is in linux-firmware. The more recent, more stable firmware version 88.2 (contained in vendor driver v4.0.1_6911.20130308 to v4.0.9_25039.20171107) still needs to be upstreamed.
History:
- Upstreaming attempt #1 (superseded)
- Upstreaming attempt #2 (failed/stalled)
