I did some experiments and see what appears to be serious errors in dmesg.
(not experienced in reading these).
I boot, and then look at slots:
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 is normal. I'm usi
I ought to qualify what I am saying here. To be clear this application does
not appear to be looking for a spidev2.0. All said I am still not getting a
change in state. I had a similar problem with GPIO's yet that went away
with the latests updates, this however seems to be sticking. No change.
I backed away from the previous application this one is not the same. It
appears to be okay ...
root@beaglebone:~# ls -lh /dev/spi*
crw-rw 1 root spi 153, 0 Jan 27 02:43 /dev/spidev1.0
crw-rw 1 root spi 153, 1 Jan 27 02:43 /dev/spidev1.1

For more options, visit http://beagleboard.or
ls -lh /dev/spi*
remember you application was looking for:
open("/dev/spidev2.0", O_RDWR) = -1 ENOENT (No such file or directory)
so make sure you application has the correct port name..

I am trying to get the SPI bus to work, unfortunately it will not change
states. Is there something obvious that I am missing. I believe that this
ties into my previous post on strace and is the reason that I cannot my LCD
to work. Thanks in advance to those that respond to this post.
