Thanks for your reply. Sorry that i am not very clear about Signals are

No. It is not possible.Signals are missing on the expansion headers
to implement ether-cat.
It cannot be done.

After installing CCS with the PRU compiler, you can simply just use the
compiler as a command-line compiler (like all the other TI compilers) and
ignore the CCS IDE. The installer is only about 20MB download to start with
and then it downloads the rest as needed. It's a quick install on Linux
Mark, it is not CCS specifically that I have a problem with. I have a very
strong aversion to having JRE on any of my Windows machines. So, if the
tool is not made available as a separate native windows ( or perhaps *NIX )
binary, I probably wont even give it a second look.

Well, install it, copy the PRU directory somewhere else and rm -rf the CCS
directory - no more JRE. There is no dependency on the CCS IDE from the
compilers.

I am also very interesting about this.

point. The numeric part could be done using Xenomai.
Apparently the use of SPI with the PRUs is

The details are all in the TI manuals, or you can reference an excellent

I need to make sure I'm understanding correctly. If I want to use PRU1's
pin 8 as an input, should I use the address 0x8e0 or 0x0e0? Should I set
the mode to 0x26 to use input and enable the receiver? Thanks for the help!

In the pru, R31 is for input, so in that table you're looking for pin
pr1_pru1_pru_r31_8. That's on P8.27, which is used by the HDMI framer. If
you *need* to use this pin, instructions on disabling the hdmi framer can
be found by searching this group.
Of course you'll have to enable the receiver,
Hi,
Thanks for these informations.
But I would like to use the PRU to get data from a fast ADC connected by
SPI. I get that there is no example of SPI connection but is it possible ?
It seems that the PRU can only access to UART, CFG, eCAP interfaces. Am I
right ?
Thanks.

Thanks Jason for the links and all the others for their further questions
and suggestions.
I'm a BBB new user and I think that PRUs really set the BBB apart from most
of other boards.
I'm looking forward doing things with them as well.
