Dear all,
To make a system with a minimal footprint, I am compiling my own kernel for
the BeagleBone black.
With this kernel I am trying to use the PRU using the uio-pruss (which
memory maps the PRU memory and offers interrupts to userspace).
However, I cannot access the PRU memory.
I tried to
Hi Michael,
Are you using the Black or Blue Beaglebone?
It seems that you are using the term bricked for not being able to connect
to the BBB.
For me it would be bricked if I cannot use anymore at all, so also not when
connecting every possible cable. For the black it's very hard to brick it
like
For I workshop we had to use dd to write zeroes to the typical location of
uboot.
That would be breaking the uboot partition.
Note that uboot is very flexible. It has some useful predefined variables
through which you can easily configure booting. For example, uboot just
calls: run bootcmd.
So if
Could you refer to which version of the image or code repository this
applies?
I have a BBBlack.
Maybe I could try it.

Typically, things start failing after changing something.
What changes did you make in which scripts?
Is 192.168.7.2 exposed via the USB?
If you check your network interfaces (e.g. ifconfig) does it still list the
usb interfaces?

Hi,
Why not separate the two questions in two dedicated mail threads?
As for question two, I guess you are starting the service from a command
line outside of the X environment.
In that case you want to set the DISPLAY environment variable.
You could also have the service start as part of the gra
The instructions below do not flash the onboard eMMC.
So you will need to press the button every time to force booting from the
SD card.
You probably want to use dd.

The am335x_pru_package uses the overall memory map base and length that
are set by the uio_pruss module on /dev/uio.
The offsets to the different registers within the chip are the specific
parts.
The software package uses the revision of the pruss interrupt controller to
select between pruss versi
You do need to make sure that Kali is compiled for the ARM and that it has
the right kernel modules to support the beaglebone hardware.
I know from experience that you can crosscompile the stable kernel for
beaglebone black, but the custom kernel that is used in the beaglebone
image has better har
There is a default ubuntu image installed.
This image also sets up the beaglebone to act as an USB ethernet adapter.
You can always connect to a network or directly to a laptop using a regular
ethernet cable.
There are also 5 pins for terminal access (also at boot time) for which you
can buy a USB
With auto MDI-X, there is hardly ever a need for crossover cables:

In my case a regular cable does the trick to connect the beaglebone to my

Before looking in to anything else.

You might be able to get it from /proc/config or/boot/config as described

Hi Stephan,
This is already the third post you did on the topic.
Could you provide some more details?
Are you using the uio_pruss from the kernel directly?
It creates 8 devices /dev/uioX, for each interrupt line a separate device
and sets the memory ranges on the 8 devices.

The links and movies are all about the ubuntu image.
There seem to be two approaches for flashing a ubuntu image on the eMMC:
1. Use a flasher image
2. Use a ubuntu image and configure it to automatically flash
I guess either approach should work.
If not I would connect a cable.

It sounds like you are mounting folders in your /boot and /home directories
on the BBB which you don't mount if you just mount the SD card in ubuntu.
On your BBB you could use the mount command to show currently mounted
partitions.
Then you can try to mount the same ones in ubuntu.
