March statistics have arrived:

IRC traffic on #qi-hardware and #m-labs:

The mailing lists:

http://downloads.qi-hardware.com/people/werner/stat/ml-qihw-1403.png

The mailing lists had their most quiet month in the last half
year, with posts on "the usual suspects", migen fixes and NetBSD
on M-Labs, and Y-Box progress on Qi-Hardware. On the 31st, also
the Nanonote EOL discussion flared up again.

On IRC, #qi-hardware traffic dropped - as I predicted last month -
by about a third but was still rather busy.

And I need to correct the last results for #m-labs: that supposed
vow of silence I observed last month was me not updating the right
files. It has in fact maintained a fairly constant level of
activity for over half a year now. Usually much less than on
#qi-hardware, but more steady.

Re: Nanonote End of life

Hello everybody,

Regarding news around Ingenic MIPS SOC, you could check this link http://linuxgizmos.com/mips-based-newton-module-takes-on-intels-edison-in-wearables/
May give some ideas.

Y-Box: more DFU, and beyond

I wrote:

Done.

Done as well, even with names (which are a messy to implement,
given the way USB handles strings):

# dfu-util -l
...
Found DFU: [20b7:ae71] devnum=0, cfg=1, intf=0, alt=0, name="KL26"
Found DFU: [20b7:ae71] devnum=0, cfg=1, intf=0, alt=1, name="CC2543"

Now I can flash the firmware of both chips conveniently via DFU
and will need the test fixture (for SWD or the CC2xxx debug
protocol) only for boot loader changes (or for new prototypes.)

I also wrote a simple implementation of the communication between
the two chips (one-way for now), found a bug in my handshake
protocol (improvised around it), and can now control either LED
with a user-space utility over USB.

Next: make the protocol bi-directional and enable it to send more
than just one byte. And then it'll be time to actually put the
radio to use.

I'm not quite sure yet how far I want to go with the radio at the

Nanonote End of life

Quite sad btw to hear about the nanonote's end of life btw. Really
quite a useful device for something so small! Though I guess now
really instead of looking to the past it is time to look to the
future. If there is to be any sort of nanonote successor - or even
something completely different what could that be? What device is it?
What does it look like?

I read through the individual posts in feburary ("Nanonote End of
life"). I think one thing that struck me and I apologise as I'm about
to go off topic is something that I went through a little while ago,
namely with trying to buy a new 'phone.

It's really hard (if not impossible) to find a open/free phone to use!
Can discount microsoft and apple straight away as they are totally
closed. Android is partly closed. The hardware in android's case more
than likely needs binary blobs as well.

That leaves a few others -- firefox os, ubuntu touch, Neo900 and
soforth. Though even these have their problems. Neo900 looks good but
I can't see it selling much with a price tag in the order of E500-700
(That's what about $600-800?). That then leaves firefox and ubuntu --
though who knows how open and free their hardware is? And if the
hardware is, the software might not be -- Firefox OS if you try to
root it you loose your warranty on your phone (
https://support.mozilla.org/en-US/questions/967076 ) . Plus firefox os
supports advertising (*yuk*) and "in-app" advertising (*double-yuk*).
Not sure about ubuntu touch though what if they do the same? Where
does it end? Spyware in ubuntu touch and Firefox OS because of ad$?

I apologise about that mini rant. But I guess what I'm trying to say

Y-Box: DFU and boot loader (KL26)

Good news: DFU and boot loader finally work.

Here's a video to prove it:
http://downloads.qi-hardware.com/people/werner/anelok/tmp/Y-Box-DFU.ogg

Detailed timeline:

00:02 Y-Box in test fixture
00:06 Push Y-Box onto the contacts of the test fixture
00:08 I flash the boot loader via SWD from the Ben
00:10 First pass: writing the code to Flash
00:11 Second pass: verification
00:15 The Y-Box now contains the boot loader but no application
00:20 Connect USB
00:21 Red LED: waiting for enumeration
00:22 Both LEDs: enumerated, now waiting for DFU. This wait normally
      ends after 1-2 seconds but is "forever" if there is no
      application.
00:25 Run dfu-util on the PC to Flash an application
00:29 The boot loader now sees a valid application and starts it.
      In this example, the application simply flashes the green LED.
00:32 Let's do it again (but without flashing, since we already have
      an application in Flash)
00:35 Red LED: waiting for enumeration
00:36 Wait for DFU
00:38 Time out and start the application

This will be the standard way of flashing the firmware of the Y-Box.
A similar boot loader can also be made for Anelok. I don't plan to
have DFU on Anelok for regular use, but during development it's

EOL strikes again

Digi-Key informed me that the Molex 0482580001 and 0482580002 went
End-of-Life (EOL), with a Last-Buy-Date (LBD) of 2014-09-01.

That's the nice mid-mounted USB A receptacle I use in the new Y-Box.
Alas, there's no direct substitute for it. The TE 1746311 would be
a similar-yet-not-identical emergency replacement, but then I'd
really have exhausted all choices. So let's not go there.

This means:

- have to go back to using a top-mounted USB receptacle, which makes
  the device considerably thicker (mid-mounted has about the height
  of the USB connector without much going above or below it while
  top-mounted has "claws" going through the PCB and deep under it,
  adding some 3-4 mm)

- can't design a new case just yet (but the new one will then just
  be a variant of the original one, since the vertical stacking now
  won't change)

- there'll be lots of room under the receptacle, so I can at least
  put a couple of the large test points there, maybe more.

Grrr. That's what I get for talking myself into using a part that
has no identical replacement from a different manufacturer.

General status: trying to get DFU to work. I can read the Flash but
the USB driver doesn't want to accept data for writing. I also
started defining the protocol between the two MCUs, now mainly the
handshake to ensure the master only starts an SPI transfer if the

Statistics: February 2014

Statistics for this year's shortest month:

IRC traffic on #qi-hardware and #m-labs:

http://downloads.qi-hardware.com/people/werner/stat/irc-qihw-1402.png

The mailing lists:

http://downloads.qi-hardware.com/people/werner/stat/ml-qihw-1402.png

The mailing lists maintained roughly the traffic level of the
last few months, with M-Labs (former Milkymist) being more quiet
with mainly a bit of discussion about putting the MMU to good use.

The Qi-Hardware list flared up after Christoph Pulster, last
Nanonote distributor in the West, announced that he'll soon run
out of these amazing devices.

Meanwhile, on IRC, #qi-hardware put on the booster rockets while
#m-labs took a vow of silence. The discussion on #qi-hardware was
a bit unusual since it mainly centered on Joerg (DocScrutinizer)
and me encouraging Peter (whitequark) to try new ideas for making
his life dangerously interesting, and he - with the excuse of
trying to make PCBs - exploring all the kinds of chemicals he can
mail-order from the notoriously circumspect and safety-conscious
suppliers in Russia.

I don't really expect #qi-hardware to stay at that level of
intensity for very long, so my prognosis is that it'll drop to
something like half or a third of the present level before too

Y-Box block diagram

Y-Box now has a block diagram, too:

http://downloads.qi-hardware.com/people/werner/anelok/tmp/ybox-block.pdf

Nothing really new there, but it may be a little easier to read
than the schematics and we can later turn it into a clickable
image map with links to data sheets and such.

Y-Box LED indications

Y-Box has several operational and error states that are worth
indicating. It has two LEDs, a red one attached to the CC2543
(RF) and a green one attached to the KL26 (USB), to do this.

How about the following scheme ?

http://downloads.qi-hardware.com/people/werner/anelok/tmp/ybox-leds.pdf

The normal use sequence would be:

- unplugged: no lights

- plug into PC: red LED goes on

- after about 1 second USB enumeration finishes and the green LED
  goes on as well

- Y-Box waits 1-2 seconds for DFU (firmware updates). If it doesn't
  see any requests, it turns off both LEDs and starts RF dongle
  operation.

- on RF activity, the red LED briefly flashes.

If the rfkill switch is set, i.e., if the Y-Box is used only to
connect Anelok to some USB device, the CC2543 is completely shut down
and the KL26 cannot communicate over USB (because it needs the CC2543
as clock source. Of course, even if it could talk on USB, it
wouldn't have much to say ...) In this case, the green LED would
stay on until rfkill is disabled (if ever).

Using android phone as Nanonote internet proxy

I know it should be possible (because the android capability of sharing internet access over wifi or usb), but, has somebody tried to do it?

Nanonote availablity

This is sad news. I tried a number of times to find out about
the 1000+ Bens that should at some point of time still have
existed in the warehouse of a fulfillment center in Hong Kong,
but my enquiries were ignored.

Rakshat Hooja mentioned that www.idasystems.net still had some
70 units. It may not be very convenient for individual buyers
to get things from India, especially considering that payment
is only via SWIFT, but maybe you could consider getting some of
these to make them more accessible.



As Werner mentioned, I have 70 odd Nanonotes in stock but am not really full time focusing on the Idasystems shop these days. I would be happy to sell these to people who may be able to use them for productive use at a reasonable price (We had paid USD 95 per unit to Sharism and I was thinking thinking of USD 90 as the price. SO a small loss for me but people have nanonotes in their hands).

There are two issues with this. Payment via SWIFT bank transfer involves dealing with a bank and shipping costs/import duties can add to the cost of the Nanonote. 

I had a few ideas to work around this but am also open to suggestions:

a) If enough people are interested, I can open an Paypal account (not very keen on this but it is one way to accept credit cards)

b) If there is enough interest for a group buy of over 20 units in a particular country/ address, I would be happy to cover shipping costs at my end

c) If any other distributor is willing to take the entire stock (minus a couple of units, which I will keep for sentimental reasons) I would be willing to negotiate to a lower price)

d) I would also be willing to exchange nanonotes with with other interesting  openish hardware projects (like exchange few nanonotes for a pandora or neo900 or GTA04. Not yet sure how this will work, I am still at the thinking stage)

I would be happy to hear your thought. If you are purchasing, you may not wish to flood the list so my email is rakshat-NAUB2WOEJtIjHdulDSg1yw@public.gmane.org
