I’m assuming you know about this:

This occurs because the DSP firmware authors need to move away from usage of RSC_INTMEM in the resource table. That approach has been rejected upstream, and I will be reworking by TI to not rely on this in the next month.

Thanks for the info, John.
Robert, do you want us to test the weekly updates or concentrate on the production image from before?
So, for the first x15 production run it sounds like "2015-10-25" (1)
has been choose by CircuitCo, the deadline was friday (2015-10-30)
I've incorporated all the feedback from the other threads, so 10-25
should be in pretty good shape..
Due to this part being a beast, i'm still planning weekly snapshot
updates of things we missed in 10-25:
x15: pru_rpmgs:
John just fixed this in the kernel, it'll be enabled by default with
the r25 kernel.
x15: video decode/encoder:
needs libdce, which needs ipcdev's headers *
I took the short cut with opencl, to use ipcdev's "AF_RPMSG=41" kernel
header flag, which allows us to NOT have to build ipcdev against every
kernel update...
However, it turns out libdce requires something not under the
"AF_RPMSG" flag, so i need to fix ipcdev
x15: sgx
linux module is installable via apt:
little bit of wayland/egl userspace hacking and it should be working..
(ti's sdk 2.00.00.00 has matrix-gui running on wayland, sgx works)

2015-11-01:
kernel:
4.1.12-ti-r26
remoteproc_pruss work from: John Syne
sudo cp /opt/scripts/device/x15/pru-rpmsg_client_sample/am57xx* /lib/firmware/
sudo reboot
sudo modprobe rpmsg_client_sample
Check journalctl for "hello world"
rootfs:
For shutdown, I've noticed
sudo systemctl poweroff
is just more reliable then "sudo halt" as halt doesn't seem to turn
everything off..

Hi John -
I've been testing out the new kernel and example PRU code you wrote. Is that code available anywhere to see how you did it? I want to use the PRU to control the different serial interfaces and McSPI but can't seem to figure it out on the x15.
Hi Yogi,
First, I didn’t write any of this code; all were written by TI. All I did was to pull pieces from the various TI repo’s and SDKs and then get them working on the x15 and BBB. When I did this on the bb-kernel repo, the changes were considerable, but when I did this on the ti-linux-kernel-dev repo, most of the patches had already been applied. For the source code, you will find it here:
Regards,
John
