I'm also using 4.4.27-ti-r62.  In particular, the IOT distribution.

I'm seeing strange behavior attempting to run Remoteproc.  It's like the 
PRUs are missing from the device tree.  I think.

I'm comparing a working board built with 4.4.12-ti-r31 from a few months 
ago.  This one works perfectly.

So I am comparing the contents of this directory:

/sys/bus/platform/devices

I believe the above contains a listing of the "non-discoverable" devices 
which are present in the device tree blobs.
I'm still not getting the device tree that well, so my guess here could be 
totally incorrect.

So on the working board (4.4.12-ti-r31), I see these entries for the PRU in 
the above directory:

4a300000.pruss
4a320000.intc
4a334000.pru0
4a338000.pru1

For the badly behaving board (4.4.27-ti-r62):

ocp:pruss@4a300000

Why would these be different?

If I cat slots on the badly behaving board:

 0: PF----  -1 
 1: PF----  -1 
 2: PF----  -1 
 3: PF----  -1 
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,univ-emmc

This seems OK.  I see the same after running the PRUs on the working board.

I have not made any changes to uEnv.txt.
Very baffled by this and not making progress.

Regards,
Greg
