Ultimate Devo F12E (devof12e-XMS) builds

Hello,

i think i Killed my Devo F4 First time i changed the chip everything looks good, so i installed the Deviation Version, but Windows can´t Format it
While i tried to resolder i removed the Top 3 right Soldering Pads, i think its 8-6!

Any Idea where i can get the missing connections? I think i am to stupid to find the right places to get my devo back to life
And Second Question what would happen if i Solder the Chip in the wrong direction? Because on the first try everything looks good and it doesn´t work !

Regards
Stephan

Thanks, but this seems to be not possible. I checked the code, A2 (_PWREN_PORT, _PWREN_PIN) is used to keep from shutting down for all devo:
github.com/DeviationTX/deviation/blob/ma...mon/devo/power.c#L32

If I comment this line out github.com/DeviationTX/deviation/blob/ma...mon/devo/power.c#L36
devo won't turn on (or turn off immediately)

Did you get yours working? I can't format my drive either. I have used 2 different laptops and still get the error formatting the drive. Although I am doing this to my F12E. I can see the drive in device manager and I can start the format but it fails. You all think my install needs a review?

We'll after a few hours of trial and error. This where I'm at. Can this be fixed? My soldering skills are very limited. I don't do it often an honestly my tech is way better hahaha. And tips would be great appreciated since this is my only controller so I'm dead in the water now.

I'm back in business! But I do have the cannot format drive error that i was originally having. I have used the java Deviation Uploader 0.8.0 I select to format drive and when I restart I get the USB screen every time. the current firmware I am using is deviation-devof12e-4MB-v5.x.x-2017-07-01.zip

Any help would be greatly appreciated.

I had that feeling yesterday when I 1st encountered the issue, so I figured I would ask before I get back in there with my iron. Do you know the leads so I can test continuity for the chip? That would make it easier to troubleshoot. Thanks for the response as well!

That's it! Write protect. Where does it go to? I'll jumper it and hopefully be all fixed. I also found the pinout in case anyone needs.

Hey Vlad.

What I'm doing is modding my Devo F12E to have the SST25VF032B chip. Am I using the correct chip?

Lastly the attached picture. The pin the finger is pointed to the pad is damaged. Can you help me locate where to reroute it? Under the chip that lead didn't show where it went. So I'm stuck until I resolve.

Thanks for the help by the way.

Can I use this miso connect?

Thank you Vlad, with your Informations i could bring my F4 Back to life

Here is the pinout for stm32f103vct6
If anyone else needs. I need a new battery for my multimeter. But I think I can get it fix it.

This is for the Devo F12E.

Yes, thats right for F4!
I used the schematic-PDF in the wiki section and the datasheet MPU of the to compare your table with my Devo

+1 to the list of 4MB F7 Transmitters

Replaced the memory and flashed 4MB build via DFUse 2.31
Voila

One thing i dont unterstand is how to switch to e.g. Model2 ??? ( I´m a long time user of Devo 6/8/12 but couldnt find this out)
Is there a Manual for F12E/F7/F4 out there?

another question is, should i try the A2 Pin for the 3rd 4in1 module connection?

or

EDIT: I tried to use the A2 pin for my a7105 CSN Line and all seems to work fine.
(No error messasges, i`ve tested FrskyX EU, Bayang and Flysky protocol)
Shutdown seems to be normal (1-2Seconds)

Greetings from a happy Ultimate F7 user
