Re: [Paparazzi-devel] Upload firmware-Device no found(Lisa/M 2.0)

[C. Y. Chen]

Hi Gareth,

thanks for help,

I re-installed Ubuntu and follow the wiki package again, i think maybe i've changed setting somewhere i don't know. Again, tried to upload firmware, got error "No module named usb",detail:

make[1]: Leaving directory `/home/lab071/paparazzi/sw/airborne'
cd sw/airborne; make PAPARAZZI_SRC=/home/lab071/paparazzi PAPARAZZI_HOME=/home/lab071/paparazzi TARGET=ap upload

make[1]: Leaving directory `/home/lab071/paparazzi/sw/airborne'
make: *** [ap.upload] Error 2
make: Leaving directory `/home/lab071/paparazzi'

then i download "USB interface for Python" using Synaptic(is it the python-usb package you mentioned?), upload firmware to Lisa/M seems work, the leds onboard don't cycle up and down, just L1 flash.

But when i tried to upload firmware again, get error

make[1]: Leaving directory `/home/lab071/paparazzi/sw/airborne'
cd sw/airborne; make PAPARAZZI_SRC=/home/lab071/paparazzi PAPARAZZI_HOME=/home/lab071/paparazzi TARGET=ap upload

I used the command "dmesg | tail -5", i found how many times i disconnect and connect USB cable, the message always is:

[   22.693279] CPU6: Package power limit normal
[   22.693281] CPU7: Package power limit normal
[   22.738435] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/serio2/input/input11

[  304.760611] usb 1-1.4: usbfs: interface 0 claimed by btusb while 'python' sets config #1

does i misunderstand about the python usb package or i should do some configuration about it?

thanks,
