Hello
I am installing a Wi-Fi driver on to my BBB with Angstrom runiung.
As I was compiling the driver I got this error
root@beaglebone:~/Desktop/WLAN-AIO-OSR/build# make BOARD_TYPE=arm
build udev
cd /home/root/Desktop/WLAN-AIO-OSR/build/../build/util/udev && \
./compat_firmware_install
Build dr
Yes, I have.
But the problem is still there
BTW, I am running the menuconfig directly on the BBB.
Does it still need to "env ARCH=arm"?
Thanks!

Hi Curt,
The thing is it actually worked earlier by following the already mentioned
youtube video even though the video is for Windows 8.
Actually, I am a newbie. Even I ran the same script but I am not sure
whether it was done in the correct file.

Hi,
It appears you have done everything right but any little item missed will
stop the link from working properly.
There are several questions you need to ask yourself...
Except where stated otherwise all the tests below are performed from the
BeagleBone system.

Hi Robert,
In order to see the BBB booting debug process with the help of usb-serial
ftdi cable in my laptop, I need to have Ubuntu installed in my laptop right
as I am using Windows 7 now?
Basically, I will be needing to use serial connection in putty in Ubuntu?
Many thanks!

You just need any serial terminal program that will run under Windows 7
I’m not sure if Putty will, but Windows 7 should have a “compatibility” mode …

Hi William,
I have been using SSH of putty in Windows 7 for BBB. But this will work
only if the image is properly flashed
in eMMC or in microSD card so that I can login in and connect.
But in this case, I am facing issue in flashing the Debian image from
microSD to eMMC and I want to debug

Dear Niv, dear all,
thanks for this great tutorial. I think this is exactly what people need to
start with GPIO on BBB.
Just one note for beginners: To make & make install the dts file you will
need some tools. There is a script available (thanks to Robert Nelson -
again!!!):
wget -c https://r
I've connected a battery to TP_5-8. Seems to work fine. However when the

little information to implement it.

So I got a Beagle Bone Black from the maker kit(Rev C). I'm having a issue
when using apt-get about old/expired signatures when I'm trying to update. Is
there a work around for this?

you may want to look into making smaller ( much smaller ) file buffers for
the ftp / sftp servers you're using on the beaglebone side. It's been a
while, so I could tell you how specifically, but it should be something you
can look up with an internet search or two.
On Sat, Jan 17, 2015 at 8:27 AM
A few things could be wrong but you could start off by checking your
networking device settings ( on both working / non-working PC's ) to see if
there is any differences. Passed that sometimes Windows can lose it's mind
if you try using difference USB ports for various types of devices. Stuff

Great!
Thanks for the explanation.
As you might imagine, the pru is incrementing at a very well controlled
frequency. The host program on the other hand I have very little control
of timing (hence the need for the pru!) So from the host side, I'm just
zeroing the memory address inside a "while"

Before this happened, I tried several combinations which included:

I don't believe your are following the hole instructions.
You are missing some kernel configs. Maybe you "deselect" some config
that you shouldn't have or you didn't do "beaglebone_defconfig" step
from the tutorial you posted.
You should also setup your cross compiler:
make ARCH=arm CROSS_COM
I am reading values from the ADC using the PRU. I need to timestamp the
values with sub-millisecond accuracy, but I'm not sure how to get the clock
time from the PRU. My BBB system clock is updated with a GPS, so pulling
time from that would be ideal. Is this possible? If so, how?
Regards,
Ist
To get sub-millisecond accuracy, you'll need a good timer running that the PRU
can read. The timer will have to have good jitter characteristics (within the
sub-millisecond requirement), and will have to be synchronized to wall clock
time somehow.
I haven't looked at the ADC's sampling time, bu
