Thanks Russ. I might as well use the Buffalo supply as it comes from a Placid rather than the SMPS powering the BBB/Hermes.

It should never be powered by the BBB - so not sure what you mean here.

I was saying that J2 on the Hermes connects to the clean 3.3V supply on the Cronus - this is a linear regulator already sharing GND with your DAC.

The power needs to be 3.3V

It looks like i2c is connected at last!!!

Code: 
root@botic:~# i2cdetect -y -r 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- 48 -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

Although I still don't have volume control:

Code: 
root@botic:~# mpc status
volume: n/a   repeat: off   random: on    single: off   consume: off

To stop Blue LEDs blinking (BBB):

Hi zz1969, lintweaker, any anyone else ...
I would like to mount my BBB inside a large chassis, and somehow display the BBB's power LED status at the front panel of the chassis.
Could I use the first pair of LED connections on the Hermes, run these to an LED on the front panel, then configure this LED as -
Code: 
echo power > /sys/class/leds/beaglebone\:green\:usr0/trigger
??
Thanks.

My plan was to remove the N and #1 on-board LEDs from Hermes and wire the board to replacements in the front panel. ...and have them close to momentary buttons - N by a reset button into the j_RST header and #1 by a power button into the J_P_SW header. This way the stock LED config is very reasonable, unless you had an operating mode in which Hermes was disconnected from power.

I have a problem with my setup made of BBB (Botic v5) +Hermes+Cronus (with 42/49 MHz clocks) and a PCM5102 DAC connected with I2S bus.
I can't play 96K files. All files with 44K1 and multiples are OK (88K2 and 176K4).
When I try to play a 96K file, there is no sound at all.

I've tried to change the value in the files clk_44k1 and clc_48k, but it didn't change anything.

Any idea ? Thanks in advance.

Thank you, Russ, I'll check my joints asap.
I've also checked the software configuration and I've found that /boot/uboot is empty (I'm using botic v5). Is it normal ?
How can I check which parameters are used by the botic driver ?
Furthermore, I'm using squeezelite and don't want mpd. I've uninstalled the mpd package but there is a remaining ympd process (check with "ps aux"). How can I definitely remove it ?

The standard 4 user LEDs on the BBB are different from those (mountable) on the Hermes. You could use one of the LEDs on the Hermes as a (software controlled) power LED incidator.

Yes, I mistakenly thought those commands related to the Hermes LED's, but of course they relate to the BBB onboard LED's.

OK, so I did some Googling, and on the BBB mailing list they mention that the power LED is activated by the power controller chip, not the CPU. So I imagine to emulate the power LED I would need to query this controller, possibly with the "i2cget" utility. I was hoping this would be a simple thing, but apparently not.

WiFi not coming up

Having completed my own DAC to work with BBB I am using the newest Botic distribution to test it.

My problem is not directly related to the driver rather the overall distribution.

It fails to get a DHCP lease when manually bringing the wlan0 interface up with ifup wlan0. Adapter works with the stock Debian on Rev C of the BBB. It should really come up automatically but doesn't.

Dongle is RTL8188CUS.

/etc/network/interfaces
Code: 
auto lo 
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
    wpa-ssid "ssid"
    wpa-psk "passphrase"

iface usb0 inet static
     address 192.168.7.2
     netmask 255.255.255.0
It is the stock image then:
Code: 
apt-get update
apt-get install linux-image-4.0.0-botic5
change opts to:
Code: 
optargs=snd_soc_botic.ext_masterclk=3 snd_soc_botic.serconfig=--I- snd_soc_botic.pinconfig=compat
flash to eMMC
reboot
edit /etc/fstab to add share
edit /etc/network/interfaces (as above)

I also tried Boticizing the stock distro and that caused the same issue so perhaps the module isn't in the kernel? given I can scan for networks, etc that doesn't make sense though... Something specific to the Botic options though it would seem.

Any suggestions on what to try next?
