They're offering an industrial motor controller based on an BBB and should
have solved this problem.

Starterware does not support access to eMMC. To do that, you would have to
implement MMC-support to their HSMMCSD-library in order to make MLO able to
boot APPs from there.

Hi everybody,
My question is, I can boot starterware
Hi,
there are some LCD-capes available out there for BBB, mainly with very vew
documentation. So I'll ask this here: which of them is supported by Ubuntu?
Thanks!

What ever causes this (changed) behaviour can be found on your on-board
eMMC. There something seems to have changed with the bootloader which now
lets the BBB boot from external SD card first.
May be you installed Ubuntu? AFAIK this modifies bootloader in this way.

EHRPWM functions of AM3358 are running with 100 MHz. Thus the smallest
possible half pulse width is 10 nsec (10 nsec of and 10 nsec on for a full
period).

Hi,
according to http://elinux.org/Beagleboard:BeagleBoneBlack#Board_Shipments
board shipments are decresing constantly for some months. What is the
reason for this? When I have a look to distributors of hardware they are
still not available without longer delay, so what is going on here?

I got mine meanwhile, for my application it fits perfectly (don't need
on-board MMC and HDMI). Finish looks good and it is working first few hours
properly. So it seems to be a great piece of hardware.
One thing to note: comparing to the original BBB it comes without
Micro-USB-cable but within

Well, that is because you are trying to access the GPIO from user space.
If you wanted to access the GPIO from kernel space, you would use a similar

I found a posting at TIs webbord regarding this problem. There a guy from

is not connected to a (switchable) output pin on the BBB, only power of/on

So setting a GPI to HIGH just by connecting it to 3.3V directly would be a
problem? I assumed GPIO-inputs are always high-resistance!?

This doesn't answers my question. So to describe it more clear:
- board/CPU is powered and running
- SYS_RESETn is HIGH
- GPIO is configured as input
...so all preconditions mentioned in BBB manual are met.
Now when I want to set a HIGH signal to that GPI, can I connect it with
BBBs 3.3V
Hi,
I try to write some data to EEPROM of BBB out of own (bare-metal) software.
Reading data works fine and code for writing should be OK too,
unfortunately data are sent to EEPROM but not written.
From schematic I found EEPROMs WP-input has to be pulled to Vss so I

I have a problem with an own, custom cape. When the cape is not connected,
