Sorry , the Devo7e tempts me ..

Lots of catching up to do ..


Walkera DfuSe does not support backing up firmware. And as far as i know noone has bothered trying to write one themselves, as DfuSe does its job.

Read protection prevents you from doing that. These chips can lock themselves pretty tight.

If you don't have it yet buy the 10, much better radio.
Devo 10 + 4in1
Spektrum Dx9
FrSky Taranis + TBS Crossfire

+1 on this, i wish i went for a 10 instead of a 7e myself. Only having normal and st1 is annoying as you usually use normal simply to spool up the helis.

Hmmm , flash tools usually read , wipe , write and read to verify .

Sounds like it should be possible to lift the original firmware from the chip on the Tx ..

hmmmm

This might not be so easy because ST has built-in read protection (look here: STM32 proprietary code protection overview ).

Wow - OK , that looks interesting ..

So much for writing a new flash tool , or modifying the existing one to read . Hmmmm

Might still be worth a look , Hack Devo !

Well, I found the bug (though I odn't fully understand it yet), and now the J6pro binds ok too :)
So I just need to test the DSM and WK protocols, and will be ready for a 1st release.

Im guessing flysky support/testing wont be until release 2 or 3?
Im currently lying low until walkera releases a firmware or deviation has been fully tested, as i only have one tx.

If 2 people are willing to install deviation, I could possibly extract the Walkera firmware from the tx. because of the process I'd need to use, it requires 2 tx that are running Walkera's firmware. Each one would be corrupted in the process and would need to move to Deviation after running the script with no guarantee of going back.

Another problem is that even if it worked, I don't have permission to distribute Walkera's firmware, which means I couldn't actually give it to anyone :(

Because I am not sure it is even possible, and it would be quite a bit of work to develop, and don't know if there are actually anyone out there willing to proceed, I'm not really enthusiastic about spending time on it.

Well, you can count me in as soon as deviation for 7e has been tested to work with A7105.

Main reason i want to use deviation is beeing able to fly my v911's and v939 with the 7E.

Though it would be much better if walkera would release the firmware themselves.

Forgive my ignorance, but does that include DSM2, and/or is it a relatively simple mod once those are proven?
Reason I ask is I'm holding off purchase of the 7E depending on whether you think it can support other cheap receivers, such as the DSM2 OrangeRX R610 ($6), or others in the sub-$10 category. That said, I most probably will only be flying the Devo model for some time before trying to bring across my other stuff, so hopefully by that time WK have released an official firmware for easy reversion.

Do you ever sleep? :lol:

Sorry, once verified Deviation-7e will support everything supported by Deviation-6/8/10
That means (currently):
without any modification: Devo, WK2401, Wk2601, Wk2801, DSM2, DSMX, J6Pro
with A7105 module: Flysky, Hubsan

There is no 'DSM'

Ok. I've released the 1st Devo7e build here:
www.deviationtx.com/forum/builds/1312-de...ae43d-devo7e-support
It is only lightly tested, so if you aren't willing to have your Tx broken for a couple days, I don't necessarily recommend it.
It has been tested with all CYRF based protocols (see above) and found to work ok.
If anyone is willing to take the risk, I will attempt to provide quick resolution to issues that are found.

...I will go for Devo7E-DeViation tomorrow or latest sunday !!! Many thanks for spending 3 weeks especially for us 7E-Users!

BTW: I need no "going back"-path to original Firmware - and I am sure, nobody else would really need it...
Kind regards,

Matthias

PhracturedBlue, when you have time could you locate the pins needed for adding the A7105 module?

Iv got some of free time this weekend so adding one to my 7E would be a perfect project.

Also, the module will be deactivated when flying the devo protocol right? so There's no garbage data being sent over the 2.4 fhz band.

Following Xermalk's post I've been reading up on the addition of the A7105 module, and it mentions the Turnigy 9X; my question is, does it support the "v2" receivers ? HK make a point of saying that the v2 receiver is only compatible with the 9X v2, and vice-versa. Tried searching the web for an answer but didn't see one.

Untested, but this is supposed to be the original 7e firmware...

hth,
Boris

EDIT PB: Can't distribute Walkera's firmware on this site without permission. I've removed the attachment until rights are confirmed
