I just installed linux 3.16.0-bone2 on my BBB from
https://rcn-ee.net/deb/trusty-armhf/v3.16.0-bone2
Im used to work with dtbos and /sys/devices/bone_capemgr*/slots in
Linux 3.8.x So I was surprised to find it missing in 3.16
How do I load dtbos in 3.16?
Thanks

Hi
Im used to using pwm on linux 3.8.x through the pwm_test driver,
but with 3.16.x there is no pwm_test module.
Can anyone point me to some info on using pwm in 3.16?
Thanks

Hello
I have a cape with a MPU6000 and a BMP180 both connected to i2c-1
They both show up with i2cdetect -r 1
but nothing happens when i modprobe bmp085-i2c or inv_mpu6050
Im not sure if inv_mpu6050 supports mpu6000
but as far as I can read the bmp085-i2c code it should support bmp180

I got PWM working in Ubuntu 13.10 Linux 3.8, but the same API (pwm_test) is
missing in Linux 3.12+
And I can't seem to find anything with google.
Can anyone tell me how its supposed to work in Linux 3.12+
Please help!

Hello Beagles!
I'm been building custom kernels for my BBB from git://
github.com/RobertCNelson/linux-dev.git
But when I came to the PWM part of my project I found that the
bone_pwm_P8_13 dts and similar files are missing.
How do I build these?
Thanks!

Hello Beagles!
After I got my rtl8192cu_beaglebone module to compile, next step is
to have wlan0 up at boot time.
I have /etc/network/interfaces
like this:
auto wlan0
iface wlan0 inet dhcp
wpa-ssid
(also tried: wireless-essid )
But the device doesn't come up. I have to do:
iwconfig wlan0 essi
I applied the patch from the raspberrypi git and it compiled :)
I will test the module later tonight.

I have successfully compiled a zImage of linux 3.12.0 for my
beaglebone black but my image is called uImage-dtb.am335x-boneblack
and the kernel file in /boot/uboot/uEnv.txt is called zImage.
How do I boot the uImage and what ramdisk file must I use?
Thanks

Hi
I'd like to try compiling Linux kernel 3.12 for my BBB, but i don't really
know where to start.
Can anyone give me any pointers?
I'd prefer to compile directly on the BBB instead of cross-compiling.
Thanks

Ok, I did a cycle of the reset pin on the sensor board, and now it responds
to i2cdetect -r 1 at address 0x60 :)
this is using pins 19 for CLK and 20 for DATA.
with VDD at pin 5 (5V)
thanks for the link.

I'm not sure if either my sensor isn't working or if it is something else.
I've tried all combinations of 17,18 / 19,20 / 21,22 / 24,26
and
i2cdetect -r 0
i2cdetect -r 1
i2cdetect -r 2
but nothing shows up at 0x60, the address of my sensor (MPL115A2)
