Re: [Paparazzi-devel] Lisa/L not working - bug on last commit ?

[Xavier RIVIERE]

Solve !!

Can you please provide the exact versions of v3.9 it worked with and which one it doesn't work with?

Did you check that you are using the unmodified version from the Paparazzi repo, so now changes you made yourself?

Easiest to check is with "gitk --all" which will show you the branches graphically... and best post the SHA1 of the commit you tested it on.

Also make sure to run "make" after pulling.

Not working version : SHA1 ble24328dac72c80a4ac5650f12ef56c390dd800

"Make" was done ;)   and no change from me here (and today, I'm behind 2)

in master nearly all the low level drivers are ported to libopencm3 and also the new I2C driver is used.

In v3.9 the old I2C driver is still the default. If you want to test it with the new driver, add 

<configure name="USE_NEW_I2C_DRIVER" value="1"/>

to your firmware section.

Yep... That's it... I just put this line, and it's working !! with the v3.9... so the problem is in the old one

Possible, but I very much doubt it... it was just some renames/cleanup and some sim fixes...

More likely that it is the same old I2C issue that happens now and then, with the old driver it sometimes gets stuck...

Yes, you're right.

I got a similar problem when I first test my Lisa/L board, as I didn't connect an IMU. So it seems that if there is no answer on master-read call, the program just stay waiting. I will take a close look to the new driver.

Thanks
