Hi,
there is a funny thing in the schematic of the BBB I do not understand: the
output of the 24,576-oscillator (which itself can be enabled/disabled via
HDMI_DIS-line) is connected to GPIO3_25. What is this used for? Why is the
clock feed into a GPI?
Thanks!

When creating a new project I only can choose the SoC type, which is AM5728
in this case. According to the feedback I got from the E2E-forum at TI,
this type is suitable and can be used for AM5729 too.
OK, now I have my Beaglebone AI, installed TI's CCS, found a suitable
compiler for the AI's SoC in CCS, and want to start with a simple,
bare-metal application to try things out.
So my question: what's next? What is necessary to e.g. have a timer which
lets one of the user-LEDs blink slowly?
I recently got an information about this: https://halaser.de/e1701c.php
It is a 5-axis CNC controller which can be used together with a mill or a
laser. It obviously is a BeagleBone with a cape - but to be honest I have
no idea if this cape can be bought separately and if it runs with a normal
Hi,
I'm running a StarterWare 2 based application on an BBB which makes use of
a USB serial interface implementation based on the StarterWare example and
by using a .inf-File which is similar to "usb_dev_serial.inf" which was
provided by TI in same StarterWare package. Of course VID and PID
Cool idea, I take three! :-D
For me it would also be fine when HDMI output and/or on-board MMC are
missing on such a BeagleBone...

What is running on your board exactly? When it is an Linux/Ubuntu, there is
nothing special, you can use any TCP/IP/sockets documentation for Linux
that is out there.
When you are using StarterWare bare metal code, you will find it makes use
of lwIP. There is a extensive documentation

Same here. A cheap board that is not available is valueless, so a

in Germany (and as it seems in Europe in general) there is currently no

I'm trying to set up a fast timer interrupt using CLK_M_OSC as clock source

Hi,
I'm just doing some first steps in bare-metal programming of BeagleBone Black.
I downloaded Starterware and CCS vom TI, got the correct .gel file,
imported the GPIO-Example (LED-blinking) from Starterware into CCS,
adjusted the project settings to work with newer ARM compiler version
5.1.1
into the internal ram and executes it.
much more faster than mmc handling...
When I connect BBB via USB and without MMC installed I get access to a
drive with some files on it including a u-boot.img and a MLO file. Is
it possible to utilitise this drive for own bare-metal applications
too and
in order to use it on BBB.
Thanks for the information!
