I have a TGY 9x that is playing up on eePe ... I already had to 5V bridge the SP Basic board to get Aileron DR switch working again.

The radio will just not read / write to eePe ... but my FS 9X has no trouble at all with also an SP basic board.

My question : If I swap out the factory board for the AR9x board ... what are the options on FW I can flash it with ? At present I use the latest version of er9x in my 9x radios and would like to keep to similar to avoid learning new routines.

I am surprised that there is not a sub-forum for the AR9x upgrade.

You have two options. Ersky9x, which is basically the same as er9x but with more features.
The other option is opentx.

If you are thinking about adding new switches, changing existing 2 position switches to 3 position, sliders, bluetooth, RTC, etc, then you really want Ersky9x.
Yes, I'm biased

Tks Joao .... simple answer.

OOPs ... Which ersky9x ? For the ar9x board ??

Ersky9x_rom.bin.
The same as for the skyboard.
You will have to enable the ar9x board in the hardware menu after you install the firmware.
To enable the hardware menu, which is protected, just turn your radio ON while holding the left horizontal trim to the left. Release it after a second or so...
Now navigate to Radio Setup / Hardware and enable the Ar9x board option.

Or not, with recent test versions. The AR9X board uses a processor with 512K of flash memory, the SKY board uses one with 256K. Ersky9x now reads the processor ID and checks for 512K of flash. If it finds 512K it sets the AR9X flag automatically.

You didn't tell us before?? At least I don't remember reading it
Anyway, I stand corrected then. And it is a nice improvement, thank you
But the setting is still there, shouldn't it be removed then??

It was the quickest way for me to add the feature. Specifically, on the SKY firmware, if the larger processor is detected then AR9X is turned on as is "Software volume", neither is turned off automatically. The AR9X option is turned off for the 'PRO.

It is likely I will need to build a specific version for the AR9X at some point. The firmware is approaching the 256K limit of the SKY board. My intention is to have 1 version for the AR9X board, and two for the SKY board. The SKY board ones will support only some of the language options so that between them all languages are supported. That will save a significant amount of flash for the SKY board.

Thanks Mike. You know, I have never thought that the firmware could be reaching the limit on any of the more powerful boards And you always save flash whenever you can.. It's impressive the amount of features and hardware support you already did put on this firmware. And it keeps growing.. Thank you.

I need to update the bootloader of my AR9X board in order to flash the last FW which exceed 256K, actual is 1.9; I can't find where this has been discussed.
Thanks

You need the latest test version (ersky9xProvR221e3.zip) from here

Flash the bootloader from the file "ersky9x_rom.bin".
Then flash the firmware..

João

Thanks Joao but that don't work, the BL stays at 1.9; I can only go up to C8; if I flash the E3 I get a snowy screen and I can't stop with the on/off switch.

I use eepeskye ver.4.15; is that an issue ?

Please confirm you are putting the file "ersky9x_rom.bin" from "ersky9xProvR221e3.zip", in the FIRMWARE directory on the SD card, then starting the radio in "Maintenance mode" (both horizontal trims held APART at power on), then using the "Update Bootloader" option to flash the bootloader.

Mike.

Someone was having the same problem a couple days ago.. he updated the bootloader and the radio works normally now.
