Quick update from me. Realized my outputs were set to PWMSync   
I was using a imported .uav i had setup (and flew) using the Vehicle wizard.
TBH Im new to this and dont know what setting is right or not but it all works together when setting the outputs to PWM and 50Hz.
Ive got cheap (no doubt generic Chinese) 12or15A "simonK" ESCs.

Do not use output setting to 50Hz, this give bad stabilization results.
Try PWM-490Hz, well the higher you can...

[rabno1]

490Hz seems to work too. Ill try to get it flying tomorrow if the weather allows.

Rapid esc set on 400Hz

Sorry for the late reply (had some battery issues and lack of time...) but I finaly got to test the delay.

In the installed of the firmware the delay was already set to 8 so the first time the AuxMag worked.
I lowered it to 7 and it failed..... back to 8 -> OK.
Back to 7 -> OK (4 times in a row)
Then I stared from zero like mentioned in https://forum.librepilot.org/index.php?topic=1110.msg10186#msg10186

If the delay is 0 it still doesn't work (like expected)
From 1 on everything worked OK. Not one out of at least 15 failed.

I gues the one failing with 7 was a glitch....
Everthing is done without any calibration. I hope to do this this weekend.
I will unplug everything now and leave it that way untill tonight and do a fresh boot with setting to 1.
This to make sure any leftover voltage is drained from al the capacitors in the boards.

f5soh could you give me a indication or patch file for delay ?
also does i2s inits before mainport?

[f5soh]

Mainport init is after flexiport init for Revo.

So what if we init main first what will happen ?

Will test power swap on main and flex for gps see what it does

[Jhinta]

Intresting. Power swap made it possible to have 4 (but esc dont arm 3 does arm but yellow)

Can be an interesting way put Flexi in last position.
But this maybe made the delay dependent on others port configuration.
example:
Mainport as telemetry / i2c ok
MainPort disabled / I2c not ok

[rabno1]

Sorry to be a pain in the ass noob but can someone tell me what i need to edit to add the I2C delay? Im trying to use another branch (autotune) and it doesnt have the delay built in i need for my external mag to work.

[f5soh]

patch is just above:

thanks again

Hi guys,

I have been trying out auxmag (I2C) and can report the following:

Configuration:
- Revo Nano
- 250 frame
- PWM Futaba receiver
- Rctimer NEO-7M GPS & MAG V2.0 (UBX & I2C)

Operation:
- GPS health: green
- Homeposition: set
- I2C health: green
- MAG: health: black (in complementary mode) green (In INS13 mode)
- I get regular updates of data on settings/data objects/auxmagsensor
- for my configuration pitch=180; roll=0; yaw=0
- I have only been able to get a good calibration once; calibration normally fails. When calibration succeeded, AuxMagSettings/mag_bias was very high ~10000 and mag_transform values were very low ~0.05
- All stab and atti health indicators are green, but stabilizatrion engine is not really working. AI is all over the place and compass does not show correct bearing.
- Randomly (I cannot link it to any particular event), settings/data objects/auxmagsensor stops beeing refreshed and Auxmagsensor tab shows no change whatsoever and health indicators stay green no matter what I do
- Only way to get it back is to reboot nano controller.

Any ideas?

Thanks.
