Here is a link to the ROM Monitor/Debugger commands, SD boot, and more TAQOZ info Don't forget - the Monitor/Debugger/SD routines can be called from your PASM programs. So you can use these to send/receive serial
The next boot ROM will pack a lot more TAQOZ into it and hopefully we can have it boot directly into TAQOZ if no other boot method is found rather than simply putting the chip to sleep to save batteries as was the case with P1. However TAQOZ could still indeed have sleep timeout on it if Chip still requires this feature. If boot sequencing falls through to TAQOZ then it can have its own higher level boot methods in regards to Flash and FAT32 SD etc.
TeraTerm is a fully supported full-featured and Open Source terminal emulator for Windows.
Yes, there is something totally unique about the bit sequence in "> ", even with a variable gap between the two characters, that allows definite baud detection.
I am running around and checking boxes, NO micro USB cable anywhere, why not the same as used for the PropPlug, could have fit.
Damn.

microUsb is more common these days. and more importantly, more robust than miniB. In case of damage, it's the cable plug that will usually fail, instead of the socket. Always easier for a customer to replace a cable. That's the thinking.
As for you not having one, that's annoying.
We did add the cable and SD card as optional items at the product page, right below the eval board. And the text stated they were not included.
Point taken that the info was easy to miss when purchase speed was priority!
So glad many of you are getting boards for Chipmas!
I tried underscores first but I tried whitespace and neither one worked. I'm sure it's something stupid..
*edit
Once I gave it some power it worked. I feel dumb now
Are you saying it doesn't work with just the power from the USB connection? It requires a separate power supply?
I just tested it with my desktop and had no issues. It could be the usb cord I was using too. I have some low quality cables I should just throw away already.
correct. Aux psu not required for moderate current use. The PC usb port will typically be able to supply 500mA. Using a powered hub recommended if your PC ports are already heavily loaded!
As I could understand, the issue with entering Taqoz from the terminal was the wrong autobaud sequence used. Not a usb or power connection issue.
I think we need a list of first steps connections and scripts put in one place.

It was a couple issues, I was using the wrong sequence first but I also had a bad usb cable. I noticed the led brightness increase when I plugged in the brick. I've also noticed some of my usb devices have a "weak power on" sequence. IE when plugged in, leds are dim until port is enumerated. I did consider ordering a USB cord, I guess hindsight's 20/20.
The main issue was a failure to RTFM! Funny thing is I read the paragraph with the sequence to enter TaqOZ more than once.. Blame the excitement. TaqOZ is pretty well documented, just trying to get my head around it right now. Just playing with blinky leds but I'm very happy we have this interactive REPL. It should make things really easy to test once I understand it a little better.

Yes- those LEDs are powered by the 5V rail to reduce switching current interferences on common 3V3. The PC power source would usually drop a little more voltage than aux, hence the brightness difference. Well spotted! Maybe that's a feature to determine power src!
Is the Goertzel add on module supposed to help with Voice Recognition?
Not really. It's for cyclical measurements when you want to measure phase/delay or amplitude, especially when coupled to its own reference. It will have lots of uses, but for something like speech, ADC's and software would be better.
We are going to have a bunch of add-on boards arriving right after Christmas which we will build soon. This will give everyone VGA, HDMI, USB, audio, Goertzel, lights, buttons, etc.

You can upload MP4 files that are under 10 megabytes.

Yeah, every app that I've got wants to export the .mov file into an .m4v, which the forum SW doesn't seem to like... Oh well:-)
I finally found a micro usb and was waiting for TAQOZ to show up as final choice when nothing else is going on.
Why is that greater than, space, escape needed?
Anyways my P2 works and I do have a TAQOZ# on my Parallax Serial Terminal.
Time to explore...

Ah.. seems @Cluso99 has done that a couple posts above. Fantastic. Cheers.

You can convert m4v to mp4 via VLC.

@"Oldbitcollector (Jeff)" - Great to hear from you! I've missed you.
Ditto. I should be a Chipmas!

Niiiiiice!
I just had to do it...
