Firmware not being built properly

I am having some issues with the firmware that I’m bulding locally not working. I am able to flash my device via the online IDE just fine, and I can even download the .bin from the online IDE and flash it to my device no problem, so it seems there’s just an issue with things not being built correctly.

I am compiling my firmware locally. I have installed the toolchain and I’ve successfuly been able to flash tinker (and my own custom applications) onto a photon with the command

make PLATFORM=photon APP=tinker program-dfu

however when I simply change “PLATFORM=photon” to “PLATFORM=electron” and attempt to flash tinker to my electron, the device enters safe mode and the user application is not executed.

Upon putting the electron into serial mode and sending the “s” command via a terminal I get the following output:

{"p":10,
"imei":"35316xxxxxxxx",
"iccid":"893407650xxxxxxxxx",
"m":[{"s":16384,"l":"m","vc":30,"vv":30,"f":"b","n":"0","v":6,"d":[]},
     {"s":131072,"l":"m","vc":30,"vv":30,"f":"s","n":"1","v":10,"d":[]},
     {"s":131072,"l":"m","vc":30,"vv":30,"f":"s","n":"2","v":10,"d":[{"f":"s","n":"1","v":10,"_":""}]},		    
     {"s":131072,"l":"m","vc":30,"vv":26,"u":"6D39B3A5B3573AC3F330AE1B963BEE6DD72B26EF918F9A257AD90B47A80A3302","f":"u","n":"1","v":4,"d":[{"f":"s","n":"2","v":30,"_":""}]},
     {"s":131072,"l":"f","vc":30,"vv":0,"d":[]}
]
}

I researched this a little and found that the vc != vv is not a good thing, meaning the firmware did not pass all the verification checks. However, when I change the platform to photon and flash tinker to my photon device I have laying around, I get a similar output, but with vc and vv being equal in all instances where they appear. Is there anything else I need to do besides changing the platform to build for the electron?

I have tried re-installing the toolchain, but that did not help. I have tried this on both the develop and latest branch, both with the same results. I have also ran it with the “clean all” command. Anyone have any idea what’s going on here?

I see this occasionally. I find that deleting the firmware/build/target directory clears up the problem. Sometimes make clean PLATFORM=electron will fix it as well, but deleting the target directory seems more reliable to me, anecdotally. If you build your app using an external directory APPDIR=/path/tosomething, also delete the target directory in your APPDIR.

What branch are you building?
If it’s a develop branch, you might need to add PARTICLE_DEVELOP=1

Entering Safe Mode also indicates that the app version you built and the installed system version on the device don’t match.
Have you updated your system firmware too?

What does particle serial inspect tell you about the versions of the installed modules?
The 10s in this line indicate that you are not up to date with the system

     {"s":131072,"l":"m","vc":30,"vv":30,"f":"s","n":"1","v":10,"d":[]},
     {"s":131072,"l":"m","vc":30,"vv":30,"f":"s","n":"2","v":10,"d":[{"f":"s","n":"1","v":10,"_":""}]},		    

0.5.1 should show you 15 for s1 v and s2 v.

I think the same build works on your Photon because Safe Mode Healer (or you previously) has updated your system firmware in the past already, but for the Electron Safe Mode Healer won’t kick in to save your precious data allowance.
So you need to flash either your own system parts or you update to the official 0.5.1 version as shown in the release notes.

You could also perform a particle serial inspect on the Photon and check the differences.

What Scruff said. I didn’t see that you were building from firmware/main. Build from the firmware/modules directory, instead, and it will upload the system firmware that matches the tree you checked out using dfu-util. I was thinking you were already doing that.

Updated to system firmware version 0.5.1 and it works! Seems like such a simple fix in hindsight. Thank you guys very much for your help.
