Which is the latestworking state in arduplane-fw/bl for pixhawk 2.1 the cube?

I change from px4+nuttx to arduplane+chibios (3.9.8?)

Now i have no power on my vdd_5v_periph_en line for powering the gps-port and i2c-port.

I have no idea, how can i get the normal function back.


Try the latest snapshot from master plane, some changes have been done yesterday to the power rail power sequencing.


You mean this Link?

Ist the vdd_5v_periph_en Pin activated? Ich miss the Power on GPS.

Mandy thanks.

i use upload.py with the firmware.ardupilot.org/Plane/latest/CubeBlack/arduplane.apj
without sussess. The Power for GPS keeps down.

Is there all right?

looks like you have an hardware issue then.

I can not beleaf this, because the power-supply of vdd_5v_Periph is protected by BQ24315, a overvoltage and over current circuit.


And i remember that the LED from ArmSwitch not works since the update of chibios.

So i think, the problem is in the firmware.

Sorry, you are right.

There is a short circuit in the last stage of power supply.
Possible the Diodes, Capacitors or the BQ24315 itself.


Now i have the result for my research.
The BQ24315 has the short circuit.
The reason is probability a short circuit in i2c.

But i wondering anyway, the BQ24315 shall protect me for the short circuit.
I do not realy understand this behavior.

Are you sure you aren’t seeing this issue?

Ah yes, this comes to late for me.

I receive the Email from my reseller after i upgrade the firmware.

Anyway, i do not understand, why the chip does protect against the input-overcurrent and not the output-overcurrent.
