Hooking up Logic Analyzer ....Help please

With the nightly build, try adding the line "force = 1" to the modules section in hardware.ini. The error screen will still show up, but after clicking through it the nRF module should still be enabled. See if you can bind and fly, and if it flies smoothly. Check if it resets when switching to other models.

Does the missing module screen still show both nRF and multimodule?

ok loaded the standard nightly and added the force=1 and it says missing module when powering up as it did before..

Yes it says both missing nrf and multimod but if i hit ok on the screen it does not reboot it goes to the binding process but it will not bind to my cx10

It sure seems to me the cpu is not receiving data from the nRF. I looked at the 4.0.1bindtocx10 analyzer data. It didn't look like nRF data, and I don't know the other chips enough to tell if it's valid or not.

Here's a build that has the workaround posted here . If this works it would confirm the code isn't getting data from the nRF. This is from the nightly plus a few things. You'll still need the "force = 1" in hardware.ini.

k i give it a try and report back....

it powers up and says missing module NRF and no longer says missing multimod but it still will not bind to the cx10 ..i can switch between model files with out it hanging tho

Ouch. Haven't learned much. With 4.0.1 it seems data's not received from the nRF, and there's some difference between 4.0.1 and the nightly build. Possibly the nightly is not able to send data to the nRF. Does a cyrf protocol work with the nightly?

Can anyone confirm successfully using an nRF module with the nightly build in Devo 12?

I built the same code for my 10 and it works fine. My configuration is similar (nRF and A7105 installed individually).

At this point it's back to debugging the hardware. If it was mine I'd:
- check the 3.3V and 5V supply voltages
- check the connections to the nRF for the 57th time (all connect to the right places and no shorts between them)
- watch the spi signals with a scope to ensure the levels are good
- attach the logic analyzer and capture the spi signals and both the nRF and cyrf enable signals when turning on with the cx10 model selected

yes the cyrf works fine with the nightly i have several flight on other models with it..

I picked up a 12s from the classifieds on RCG less then a year old never used...will see if it works on it when i receive it in a couple days or so ,if it works then it has to be something in the 12 i have if not then has be something related to ether the module or the nightly or as i suspect the 12 i have now has issues from the superb walkera quality control...

Where should i be getting 5v at? from what i remember last time i checked it i am only getting 3.3v on both the vcc and the tms pins on the pcb...could be mistaking and i will check again to be sure...

Was just listing the general steps I would take. Had 5V on the mind as I'm also working on a 9x.

Looks like the 12s i bought will be here today and i will test out the module in it to see if it works and report my results...
Also i received the A7105 module from BG but i do not have any models at this time to test them out on...

Update to those been following this thread...i reveived the used devo12s and after repairing the cracked gimbal it received in shipping i proceeded to install the same Nightly Build i have on my devo8 and removed the cyrf + NRF module from my devo12 that it would not work in and installed it in the 12s and now the module works fine and the 12s binds and flies my cx-10 perfectly...I have absolutly no idea why the module would not work correctly in the 12 but works perfect in the 12s...perhaps its the difference in the board versions don't know...
