/sys/class/gpio/gpio0/direction: No such file or directory

I downloaded the binary for raspberry pi, beaglebone black and dpkg - it on my udoo dual with udoobuntu v2 However I got this error. Previously, it had worked fine on udoo with earlier ubuntu's. The error is in lines 443-447 of /usr/local/bin/udoo-arduino-build.

I'm sorry, but this tool is actually not compatible with kernel 3.14.28 and then, with udoobuntu 2.
To make it work, please use the new version of UDOO bossac, available here: https://github.com/UDOOboard/bossac

Hi @kendallgreen and @ektor5

thanks for using that stuff here. Great to here that it is senseful fro someone else!

Ok, I have not yet worked on UDOObuntu v2 BETA. What is the base operating environment? (L)Ubuntu 14.04 LTS or something different?

If the problem occurs on source lines 439-449 it depends on a changed gpio class naming.

I had rewritten this reset function in the latest branches to get a stable reset by setting the lines.

I will download the BETA within the next days an check what is new.

@ektor5 - is the new bossac mandatory and will it work on v1,1 as well?

Cheers
Tom

Unfortunately, not.

We've heavily modified the bossac driver in the kernel, now the gpios are
reserved to the driver.
You have to check whatever /dev/udoo_ard is present, and choose the right
bossac, if you are inside UDOO. This way you can be retrocompatible.

Really nice work!

PS: the base is from Ubuntu 14.04.3 LTS, it's debootstrapped from this
script: https://github.com/UDOOboard/mkudoobuntu
Hope you enjoy!

Hi @ektor5

Did you also update the Arduino Dev Environment to 1.6.5?

Thanks
Tom

[ektor5]
