Synology RS819 - Realtek RTD1296 #36

Closed RobbieTT closed 3 years ago

Is there a package that works with the RS819 and its Realtek RTD1296 cpu?

Adapter = QNAP-UC5G1T

[I did look, honest, so happy to be forcibly pointed in the right direction]

Incidentally I got this running on a colleagues NAS (already supported) and found the performance to be erratic. Looking in more detail with a USB analyser and saw the voltage drop when transfer speed and current draw increased until a momentary drop completely with the speed then building again (a sawtooth pattern). Issue cured by using a Y-type USB adapter to provide power from 2 USB ports. No more throttled speed or sawtooth transfer pattern.

Regards to all.

I created the driver for RTD1296 platforms. https://github.com/bb-qq/aqc111/releases/download/1.3.3.0-2/aqc111-rtd1296-1.3.3.0-2.spk

Thank you for the information. I will share this tip in other threads.

@bb-qq Thank-you and I should add that the current limit seems to vary between Synology models and even between USB3 ports on the same units (eg front vs rear), so if in doubt trying a different USB3 port is a valid option.

Can I ask if you tried the RTD1296 package @RobbieTT? Thinking of trying this on DS220j.

@marcosscriven My efforts were thwarted by my multi-gig switch dying and no replacement available from UniFi / UI. Being stuck on 1GbE is a painful experience when 10GbE had become the norm.
