How to update a R-XSR to ACCESS F/W using a X20S TX?

[bschatz]

So, I just got my X20S and I'd like to update the F/W on my R-XSR to ACCESS. How to I update this RX? Also, I see on the FrSky website there has been a number of updates to the F/W do I need to install all of the versions or just install the latest?

TIA

Down load the R-XSR firmware from the FRsky web site. https://www.frsky-rc.com/r-xsr/ I have created a folder on my radio SD card called "flashing firmware" Just for an organised folder structure I copy the downloaded file to this directory in sub folders with the receiver types. You are then able to flash this file to the receiver using the S-port pins on the receiver right from your transmitter.

If you bought the radio from us, it should be pretty current with firmwares already, a new version of Ethos did just release, and it is worth switching over as it fixes a bug that will drain the little memory battery inside.

Thank you Henny, I did find a video of someone using a X9 Lite, and I was able to follow along and was able to figure out to made it work with my X20S.

Wayne, The TX I bought from you is has x.14 on it, I noticed github had x.17 available when I looked the other day. But my original question was I had a R-XSR that had ACCST F/W and I wanted to try ACCESS on the RX.

Yes the R-XSR is one of the few older FRsky receivers that can operate ACCST or ACCESS firmware by flashing the receiver with your choice.

Also, it is a good idea for everyone with an X20 to bring it up to the .17 level as it fixes a bug that will drain the RTC battery in the radio.

Yes, you can install the ACCESS firmware onto your R-XSR, you will find it here:
