I want to power the board by the esc's bec's so i placed the JP1 jumper acourding to manual. But this seamse to make no difference,
With or without JP1: output connected to a esc bec the board does not power up.
With or without JP1: input connected to a esc bec the board powers up.
I am using the latest versions to date any ideas?
That's what I need to do to get my APM2 to boot remove SD card. The reset button does not work for me still hangs.
What lights are you getting? Are you getting a green power light? If you get the green light it's a boot problem if you get no light with power attached and the jumper is in, it must be something else.
Look at my page for pic of my hook-up. My understanding the SD card is used for logging and future expatiation. All set-up variables are maintained without the SD card.I have logged 8 flights now with no SD card.
I seem to have this problem as well, except my APM2 hangs at boot (blue led solid instead of rapid flasing red+blue) with the SD card in place. remove the SD card makes the board boots just fine
If you press the reset button after it's powered up, you should be fine. The dev team is working on a fix, which will be in the next version of the code.
I have been having problems as well with the APM2. Try to remove the SD card and put the jumper in. Power from one of the ESC only. This is what i need to do to get mine to boot.
I have the same problem. Ending up I have power cable going to both the input and output, even with JP1 connected.
