lost program devo 7e

If the Devo is booting and it's giving you "Missing Modules" error, that's a problem with the Hardware.ini, but the rest of Devo may be running correctly. That's why I recommend getting the basics running first before adding in the modules. It looked to me a few notes back that you had the basics running.

For Deviation you won't use the Walkera files any more. The Deviation file you want is in the downloads "nightly downloads" section, and the latest is a good choice (4/23). The latest file for the Devo 7e is called "deviation-devo7e-v4.0.1-becf9bd.zip". Download and unzip that file for the firmware and files. Be sure to calibrate your sticks and once that's complete, look at the protocol called "devo" and make sure it is showing without an * (asterisk) in front of it. The Syma protocol WILL have an asterisk.

If that's working then you can edit your Hardware.ini file. The ONLY edit you need to make is to remove the semicolons from the front of two lines, and no others:
; enable-nrf24l01 = A14 <-- remove the semicolon from this line
; has_pa-nrf24l01 = 1 <-- remove the semicolon from this line

Note: if you have soldered the CSN line to the TMS pin, use "A13", and if you soldered it to the TCK pin, use "A14". When you reboot, if you've got it wrong, you'll get a missing module error, so just try the other one. If the error continues, please post the hardware.ini file.

Do you have photos of the wiring you've installed? If things aren't working after this it's possible you have a problem with the wiring.

here is the folder

.ok loaded the newest file as above.
removed semicolns and now i get
protocol mismatch
0801fc6c
0801fc68

You need to upload the same version of firmware and filesystem. Just take the most recent build, install it and filesystem from the same zip.

hello
is there anyone here this morning that maybe can guide me to what im doing wrong getting this devo to work?
I have removed the nrf module but wires are still there,
I have started over and loaded the dfuse file to radio.then i went to usb in radio,reformatted drive,then wrote all the files to radio
except the debug and defuse and updating folder...after i do this i turn radio back on and i get the error (missing modules cyrf 6936)
but when i click to exit it it just beeps and stays on screen?

Post your Hardware.ini please.

; there is no need to enable the cyrf6936 module unless
; it is wired to an alternate port. It is Enabled automatically otherwise
; enable-cyrf6936 = B12
has_pa-cyrf6936 = 0
; enable-a7105 = A13
; has_pa-a7105 = 1
; enable-cc2500 = A14
; has_pa-cc2500 = 1 enable-nrf24l01 = A13 has_pa-nrf24l01 = 1
; enable-multimod = A13

The Hardware.ini file is corrupted. You need to use an editor like Notepad++ to make these changes, because the Windows Notepad program messes with line feed/CR for the file. The correct section of the file should look like this.

This could be the cause of your problems all along.

; there is no need to enable the cyrf6936 module unless
; it is wired to an alternate port. It is Enabled automatically otherwise
; enable-cyrf6936 = B12
has_pa-cyrf6936 = 0
; enable-a7105 = A13
; has_pa-a7105 = 1
; enable-cc2500 = A14
; has_pa-cc2500 = 1
enable-nrf24l01 = A13
has_pa-nrf24l01 = 1
; enable-multimod = A13

Now when i turn on i still get error. cyrf6936 but when i click on ENT it goes away..
I have asterick beside all models?this is still with module unhooked

here is board

notepad ++

Use the original hardware.ini, because you've disconnected the extra module.

Alternatively, you can install the NRF module back, and use this hardware.ini with your edits. That's what you want anyway, so try it first.

If the hardware file.ini is corrupt will you get the red error like in the pic i posted?or is that normal?
I have done so much now im not sure what to do..
should i start all over and load dfuse again then remormat drive then copy folder back to drive?

Relax. It is booting correctly now, but it's giving you an error message because you don't have the extra module installed.

You do no need to redo the DFU or reformat. You just need to match the hardware.ini file with what is actually installed.

heres what i done before reading your post...
i opened usb(radio) and reformatted drive...(empty)
then loaded all the files to usb except debug and defuse and update.md
then opened back up and removed the semicolons in proper spots
now when i turn on i get the missing module...ect
yes nrf module is unplugged...I have the ribbon cables
where i can plug and unplug it.....(if that helps)
please explain wbat you mean about the hardware ini file matching?
matching whats in the folder on pc and whats on radio?
I change the one in radio...do i change one in folder to match also?remove semicolons?on both

forgot to ask
how do i remove the astrisks from models/

Hardware.ini is used to tell the deviation system what to expect. The semicolons in the hardware.ini file tell deviation to ignore that line, so by removing the semicolons you are telling deviation that you HAVE INSTALLED that module.

The hardware.ini that installs with the system has semicolons in all lines because by default you have no modules installed. If you boot without changing it, with no other modules installed, you should get no errors.

When you install a new module, you must edit the hardware.ini file so Devo knows that the new module is installed. So you remove the semicolons for the modules you have. If Devo finds that module, you will get no errors. Thus the hardware.ini file matches the configuration of your system.

If your hardware.ini is set up exactly how you've installed your modules and you are still getting errors, you probably have something wrong with your hardware. These transmitters can take a lot of abuse -- all of us here have seen some real butcher-jobs! -- but they usually keep working! It's a learning experience.

So 1. Does it boot without error with the default hardware.ini and no module? And if so, then 2. does it boot with the module installed and the hardware.ini file properly adjusted?

The asterisk appears in front of all protocols that are not usable, i.e. because the matching module is not installed.

One note of clarification:

You should not have problems if you have modules installed but not enabled in the hardware.ini file. Well, other than not being able to use them, anyway.

If they aren't enabled in the hardware.ini, then they won't be checked for, so they can't show up as missing. Further, they are never enabled by the CPU, so shouldn't interfere with the operation of the other modules.

My normal path when adding a module is to add the hardware at the bench and then power back on to make sure I haven't broken anything in the process. Then I edit the hardware.ini file to enable that module, and turn that on. At that point, a "missing module" message usually means a bad connection of some kind.

Hell again,ok I will give another go at this..thanks for all that have helped and helping
I have started all over again,,(this is with NRF module (NOT) installedand also ohms meter used and tested all wires at pads
1.I opened walkera dfuse usb upgrade
2. I put file (becf9bd dfu file to radio)
3 safely removed)then exit
4 powered up with power and ENT pushed,
5 opened folder
