Just a heads up, TI just landed two large changes to the v4.4.x tree today:
remoteproc_pruss & sgx
remoteproc_pruss: this should be compatible with v4.1.x-ti
sgx: the “modules” should build and enter the archive when the kernel *.deb get’s built…
Here is the user space:

Hello Robert,
This is excellent news! I hope this fixes the installation issue I just reported for the BB xm, will give it a try when the deb become available.
Best regards,
Tziang
Hi Tziang,
Hello Robert,
This is really useful, thanks. I’ll consider 3.14 instead as you suggest, and 4.6 too.
Best regards,
Tziang
The sgx modules for stretch were successfully built, the build farm is
currently working on all of them, so they should get pushed to the deb repo
later tonight..
Thus, the sgx flag in the ./update_kernel.sh script is now set, so it'll
install the sgx modules by default for v4.4.x-ti kernel's going forward..
Regards,
Great news!
Any progress on getting an sgx accelerated desktop, or are we still
waiting on wayland?
From there release notes, it needs wayland 1.9..
jessie: 1.6.0
stretch: 1.10
Not a lot depends on wayland, so i think it would be a safe backport..

Looking forward to reading that guide when and if ones made. And watching a demo video 
I think there are some wrong with pwm driver on linux-v4.4 kernel.
run:
var b = require(‘bonescript’);
b.pinMode(‘P9_14’, b.OUTPUT);
b.analogWrite(‘P9_14’, 0.7, 2000.0, printStatus);
function printStatus(x) {
console.log('x.value = ’ + x.value);
console.log('x.err = ’ + x.err);
}
output:
x.err = error updating PWM freq and value: undefined/pwm0, Error: ENOENT, no such file or directory ‘undefined/pwm0/period’
root@beaglebone:~/workspace# ls /sys/class/pwm/
pwmchip0 pwmchip2 pwmchip4 pwmchip5 pwmchip6
the export and unexport file disappeared.

Hmmmm… the pwm path appears to have changed for the 4.4 kernel. Bonescript uses
/sys/devices/platform/ocp/48304000.epwmss/48304200.ehrpwm/pwm/pwmchip6, but the new 4.4 kernel path is
/sys/devices/platform/ocp/48304000.epwmss/48304200.pwm/pwm/pwmchip6 (the ehr is missing).
A quick hack is to edit : /usr/local/lib/node_modules/bonescript/src/hw_mainline.js and remove the ehr from line 95.

This got changed in:
and then backported to ti's v4.4.x branch..
Since the 0.5.0 branch of bonescript became v4.4.x-ti + with:
https://github.com/jadonk/bonescript/commit/afc63224575b014b8661ada52d553ac78140e6b6
This should pwm change would be safe to push in..
Regards,
I’m rusting on this git stuff with remote repo’s, but I think I’ve just put in a pull request with the fix.

Close, you want to merge your 0.5.0 into jason's 0.5.0.. (looks like github
defaulted to your "master" for some odd reason...)
Regards,
Well, I better pull Pro GIt off the shelf and look up how to do it right…
–Mark
github need's there own book for the web interface, although it would
change weekly..
staged it up for you:
https://github.com/jadonk/bonescript/pull/130
Regards,
Thanks…, but what did you do differently?
–Mark
So after you click the pull request button, you need to manually change the
branch..
github assumes everything get's merged into master.. (which for bonescript
isn't true right now, as 0.5.0 is a seperate development branch)
Regards,
I have tested bonescript 0.5.0-beta7.
run:
var b = require(‘bonescript’);
b.pinMode(‘P9_14’, b.OUTPUT);
b.analogWrite(‘P9_14’, 0.7, 2000.0, printStatus);
function printStatus(x) {
console.log('x.value = ’ + x.value);
console.log('x.err = ’ + x.err);
}
output:
Bonescript: initialized
x.value = undefined
x.err = error updating PWM freq and value: undefined, Error: ENOENT, no such file or directory ‘undefined/duty_cycle’
PWM still now work.

Looks like there is an error in the documentation. analogWrite’s callback only sets x.err, not x.value. This worked for me:
(Note: I’m using pinMode b.ANALOG_OUTPUT rather than b.OUTPUT.)
var b = require(‘bonescript’);
b.pinMode(‘P9_14’, b.ANALOG_OUTPUT);
b.analogWrite(‘P9_14’, 0.1, 2000.0, printStatus);
function printStatus(x) {
if(x.err) {
console.log('x.err = ’ + x.err);
} else {
console.log(‘No errors’);
}
}
