Oh, how many times have you flashed poor BBB? 🙂
I think you should be still able to use serial port to access your BBB.

😱 Many,many, many times!!! I'm just waiting for the Beagle to get hit with that power off sequence problem. Battery arrives on Wednesday.
The odd thing is last night I used HTTP,YMPD via Win7 and listened to about an hour of music!?
So far the combination of BBB/Hermes/Cronus/BII sounds better than Linux/Mint/foobar > Waveio(USB) . A veil has been lifted that I neverwould have know was there. 😀
So, thanks again to Miero and Russ etal. 🙂

Just a note on the problems I was having when trying to use the play command.
With Russ' help/suggestions the problem of
play WARN alsa: Input/output error
play FAIL sox: `default' Device or resource busy: Operation not permitted
turned out to be a Rhea clock module needing a touch up on its connections.
Also, reheated all connector pins just to be sure. A couple did look a little iffy.
Big thanks to Russ. 🙂 Have been building their offerings since the first amp on a chip they sold. Still plays and sounds very good.

Updating to Botic v4/5
To flash to Botic v4/5, is it required to have eMMC
flashed with Botic v3 already, or can Botic v4/5 be
flashed to the eMMC that has plain vanilla Debian installed,
bypassing installing Botic v3 completely?

I did a clean install of Debian for BBB and added the latest botic bits as per how to. That worked great. I did however skip some of the instructions wrt adding Debian repos. Otherwise I could not install some of the additional bits I need.
Better stay with Debian 7.8 instead of Debian 8 for now
Could have been one of the four clock pins on the pcb that I touched up, 😉 probably more than likely. 😱
This is completely nuts!!! I've been trying over and over and over .....
since Sunday to get back up to Bot v5 without any luck.
This last time when I updated the SD card from v4 to v5 and
powered off and on then flashed with /opt/scripts/tools/eMMC/generic-eMMC-flasher-12mb.sh, powered off removed SD card and powered on,
did a uname and it told me it was bot v3!!!???🙁
I'm tapped out, going back to Linux/Mint and Waveio.
When the dust settles from this development stage I'll try again.
My apologies for being a pest here and many thanks to those
who cared enough to help. 🙂

Why not run from the SD card? Problems with the card reader like I have experienced? That would explain the failed flash...

miero's Botic kernel is based on Robert Nelson's stable kernel, i.e., debian-based, so I think porting of Botic driver to Arch is dependent on miero's decision, though it appears great if possible.
BTW, I think running Arch for Hermes-Cronus board will be no problem as long as you keep USB connection using Hermes-Amanero board. This weekend, I'm going to try if this combo with latest MPD will work.

Thanks twluke!
Arch seems very light and certainly be beneficial to embedded PC like BBB! 🙂
Apparently there will soon be a BeagleBone Green this June in Shenzen.
Btw, I am a happy user of Botic 3.2. Not sure if there are sq benefits in upgrading to Botic 4/5? Any feedbacks from those experienced are much appreciated!
Cheers.

Researching the microSD card issue, I checked the solder pads under a binocular scope. I was surprised to find physical contact had been made between one uSD card reader pad and the stock TPA aluminum standoff that was usually in place on the BBB. That would ground the pad. At worst, two reader pins could even be bridged, though I'm sure that didn't occur. So be aware of the standoff type/placement on BBB!

Three options if your worried about a short there:
1) Use a plastic washer
2) Use a plastic or narrower standoff
3) Turn the standoff slightly so that there is no chance of a short.

UART on Hermes-BBB usage?
@miero, did you manage to get a dtb/dts with Hermes-BBB UART support? Maybe I missed it.
No, you did not miss it.
But it is available now:
- http://bbb.ieero.com/botic5/am335x-boneblack.dtb
- use it to replace original file in the /boot/dtbs/4.0.0-botic5/
Also there is script for configuring GPIO for LEDs and digital inputs:
- https://github.com/miero/botic-tools/blob/master/hermes-gpiocfg
And brief example script for setting/clearing LEDs and reading (current value) of digital inputs:
- https://github.com/miero/botic-tools/blob/master/hermes-gpio
Later I'll add application that will read inputs real-time and execute preconfigured scritps.
Thing not ready yet: Analog Input

Thanks, I'll test it out.
Right, I forgot there are provisions for adding buttons on the Hermes-BBB...I've added buttons to the P8 header...
Python with the Adafruit BBIO library is great for this. You can define callbacks (so no need to poll for button presses) and debounce for the buttons if needed.
I can post an example if there's interest.
