Hi,
I am using Robert Nelsons kernel:
Linux beaglebone 3.2.30-psp23
. I stacked together the following capes:
On the LCD7 cape at the place for the beaglebone I put
first the AUDIO cape, then onto that the Beaglebone.
At the place for the capes I put first the RS232 Cape
and then a breadboard cape (which currently is an empty
PCD only).
All capes have different EEPROM addresses.
When booting the kernel, I see the following messages (marked with "!!!")

With the LCD and the Beaglebone only, I can see the heartbeat on one
of the LCD LEDs. Now both LEDs are constantly bright.
One of the two LEDS on the AUDIO cape cannot be altered from userspace
(using /sys/...).
(The LCD display function is not limited by this problem.)
How can I fix the problem?
Thank you very much in advance for any help!
Best regards,
mcc
