I'm using BeagleBone Black.
PRU example code PRU_memAccess_DDR_PRUsharedRAM in PRU sw package
does not run on 3.13.6 kernel. And I found where it does stop working;
mmap(0, 0x0FFF, PROT_WRITE | PROT_READ, MAP_SHARED, nFDMem,
DDR_BASEADDR);
where DDR_BASEADDR is 0x8000.
This code works
Screw the question above, I dug into the issue something more and now I
wonder if it is even possible? According to the processor data sheet it
uses a shift register, which is filled from one register for write and
fills another register for read. Now can I reverse this direction on the
write

I found solution. I have to use interface function provided by pruss (which
I had not known).
prussdrv_map_extmem
This function solves my problem.

I took care of that in the boot device tree. Forgot to specify that, sorry.
It was in the overlay as well; I saw a comment somewhere that re-enabling it
could cause problems so I took it out.

Hello
I am trying to powering up the BBB through the header p9.. but when using
connecting the 5V to pins 5 and 6 it is still not turning on automatically.
I still need to press its power button. So how to make it turn on by just
connecting the power?
Best Regards
On Wednesday, June 26,
Sounds like you are doing something wrong. Those pins connect to the power
jack, so it should power the board. What else can you tell me about your
setup?

Sounds like you might want to try flashing the new Debian images, even if
you plan to run Ubuntu, just so you don't have to hold the boot button.

Hi Doug,
The Debian images use wicd to start the network interfaces instead of the
/etc/network/interfaces file to avoid a possible delay on boot when the BBB

Hi Gerald.. many thanks for your support.. I revised the the cape design
again and I found my mistake.. I was connecting power to pin 7 and 8 as
well.. it seams like those pins should stay without any volts applied
before the device start and supply them with 5V itself.
Thanks..
On Friday,
Glad you figured it out!

As far as I know, the default am33x-boneblack.dtb which is read from kernel
during boot does have only 3 pin addresses for analog inputs, you can modify
this by referring TRM or other dts files. I do not have my file now sorry, I

Thanks for confirming my original observation! I think John raises some
important points regarding power handling...some of which go well beyond
the context of my original post.As he suggests a software solution is
not an option ...unless you have some other platform to run the software
on!
As a general comment, whenever people are talking about edge
detection, there's an implied timing specification of the sharpness
and/or quality of that edge---there's an implied slope and setup/hold
times, and your actual V(t) may be such that it is not seen as a
valid, recognized positive edge.
