RX6R - Firmware flashing problem
I'm using Taranis 9XDP, pre 2019 ACSST and have bought a RX6R that is the newest ACCESS version. I was unaware there was a newer version or choice. The ACCESS Logo is on the RX cover.
Obviously it will not bind to my ACSST TX.
I thought I could just reflash this with the previous ACSST firmware and have downloaded this from FRSky portal and loaded to the SD card.
Whenever I connect using the reversed (+/ -) servo lead to the external RF module bay and try to reflash as I’ve done before, it says it’s unable to flash.
What am I doing wrong? Is this receiver just too new for my older system and cannot be stepped back?
Any help or guidance would be appreciated before I have to sell off this receiver cheap again ????
Where are you connecting to on the receiver?
Thanks for responding. I'm connecting via the + - SPort on the receiver to the same pins in the Taranis External RF module bay.
so the pins used on module bay from the bottom up is: signal, neg, pos. also does the receiver lights come on when you enter flash to external module?
that is correct, I was aware of the swapping g servo plug pins,etc. As I’ve had to do before. The lights do not come on the RX. That surprised me too but I don’t want to swap polarity in case I damage it. If I simply power RX normally it powers up with flashing red (F/S) but nothing with the TX flashing attempt. I get red/green when attempting to bind but it fails obviously because of the unsuitable ACCESS firmware.
well i can say its not about the firmware compatibility as the receiver would still power up, so the receiver is not receiving power for some reason. it could be a fault on the module pim or the rx S Port side, have you done this process with any other receivers?
Thanks for the help, now that I know it should possible I will do further investigation to determine why there is no power getting to the RX.
i have done this same procedure successfully in the past on X and S series receivers. Hence why I thought there was some issue related to the fact it is a new ACCESS RX. I’ll report back with my findings later.
Tried this again over the weekend and still no joy.
I confirmed that the rx is getting power during the flashing attempt (red led flashes slowly same as when powered up, F/S mode?).
I then confirmed the tx and my method as I successfully flashed spare S and X series rx's with no problems at all. Leds flashed red/green alternately until the write was complete as expected.
There is definitely something different about this ACCESS RX6R rx with regard to flashing. Someone with the rx's should do a test to see if its just this particular rx, or affects all ACCESS rx's that should also work with ACSST if they were flashed accordingly.
Thanks for your help, but its my fault for buying this ACCESS rx by mistake in the first place, I'll know for future to check as they cannot be backwards flashed with ACSST.
- @dstevenson Hi I'm not a support person but I seem to recall reading elsewhere that the ACCESS receivers will only flash exactly the right firmware. Are you sure you have the RX6R firmware not RX4R for instance? Hope this helps!
Thanks for the reply. I have definitely downloaded the correct RX6R - the most recent ACSST firmware (pre the V2.x.x update) and it will not flash.
As you say, there must be something that makes this ACCESS rx unable to be backwards flashed.
its my fault and I’ll know for again, but I wonder how many others like me will buy a “bargain” RX thinking they can backwards flash to suit their pre-2019 systems, only to find out it can’t be done, not easily anyway using the TX SPort method.
@dstevenson i can assure you that you can flash ACCESS receivers to ACCST i have done it many times, there is something wrong some where. Just to rule it out, test this by flashing an ACCESS firmware if it faults out the same then we know its not about the firmware
ok, I hear what your saying. I’ll give the access firmware a try and report back.
Sorry about taking a while to report back but I've been busy balsa bashing. The plot thickens, or I've lost the plot, either way the result is the same, lol!
I've attached pics this time of the two different attempts at flashing. I downloaded the latest ACCESS firmware and ACSST firmware from the FRSky portal. First thing struck me is that the ACCESS firmware file is .FRSK and the ACSST is .FRK. I connected the TX and downloaded to the Firmware directory on the SD card.
I then connected the receiver to the TX external module bay with the servo lead (reversed + -).
Once I try to flash the ACCESS firmware (long press of ENT) I only get an option of copy, rename, delete - no option to flash??
If I select the ACSST firmware (either the latest V2.x.x or an earlier one) and long press ENT I do get the option to flash but the flashing fails after a few seconds. The RX red led flashes brightly and the green one seems to flicker very faintly but it fails to flash and brings up the error as per pics below.
Hope this is clearer but there is definitely some difference between flashing .FRSK and . FRK file types. The Taranis doesn't even want to try and flash the ACCESS firmware.
Have you flashed ACCESS using pre-2019 Taranis X9DP ? Have you tried flashing an ACCESS loaded RX to ACSST firmware with a Taranis X9DP ?
There is definitely something different here, I don't believe it is a faulty RX and I know the TX will flash ACSST perfectly.
Hope this info is of some help to clarify what is happening.
Thanks for the advice to date.
I'm back to the balsa - at least it's not fighting back, lol!!
that is interesting, have you tried in boot loader mode instead of doing it off SD card screen. i can not remember what i used to flash think it was an old TX flashing ACCST to ACCESS receivers, we once took delivery of some ACCESS receivers by mistake ad i flashed them all to LBT ACCST.
Could be right tho the TX dosnt recognize the file being an FRSK file, you could try renaming it but im not sure if that would work, unfortunately because of current situation im working from home and not in the shop and dont have the kit to play with but ill ask a friend to try that, but that still dosnt solve your issue.
I am having the same problem. Have you had any success in flashing the rx6r?
