teensy 2.0 notrecognized in debian 8 nor Ubuntu 14.4.1

[crazyrobinhood]

Hi there.
I have my teensy 2.0 board ad it's blinking fast.
I start teensy_loader and after it says press button and I do that, blinking stops but nothing seems to change in the interface of the program.
Is there a way to check USB-serial ports so I can paste the code here?
PS. I already tried different cables and nothing changes.
Apparently in Arduino 1.6.7 the board is recognized on /dev/ttySO port.

I'd love to know if it's a faulty board or if I'm doing something wrong.

Thank you in advance.

UPDATE.
same issue on laptop with ubuntu 14.4.1 gimx keep saying to plug the teensy and in the teensy_loader the buttons are all grey.

Hi,
I don't understand what you are doing here.
Please explain what you are trying to achieve, which firmware you loaded, and which parts/options of the GUI you are using.

Hi Matlo,
thank you for your answer.
What I'm trying to do is to flash the teensy 2.0 board with the firmware of the g29 for ps4 (EMUG29PS4) under Linux.
I suspect that my board is not genuine teensy, even if there is a mark "teensy 2.0" on the board, because when I push the button the teensy loader dont' show the program and reboot buttons green. Insteas they remain grey like they are unoperable.
Is there a way to flash it with Arduino 1.6.7?
Another question, when I try to flash it, does the board needs to be already connected and assembled with CP2101?
I am trying both Bluetooth mode and DIY adapter mode. In both cases the pass of flashing the teensy is the same, isnt it?
Thank you in advance and I apologize for my english.

Hi,
Where did you buy it?

Is there a way to flash it with Arduino 1.6.7?

I can't tell what kind of loader runs on the board.
All the options are listed here: http://gimx.fr/wiki/index.php?title=DIY ... re_loading

Another question, when I try to flash it, does the board needs to be already connected and assembled with CP2101?

Only if the board has an Arduino Leonardo loader.

I am trying both Bluetooth mode and DIY adapter mode. In both cases the pass of flashing the teensy is the same, isnt it?

Yes, the procedure is the same, the only difference is the firmware to load.

My board was brought on eBay here:
http://www.ebay.com.au/itm/221863060453

It seems that my only option is avrdude under Linux, isn't it?
And I have to assemble the adapter in order to flash it..

Thanks!


EDIT: avrdude gives this:

ttyS0 is not the right device. What's the output of dmesg after plugging the Teensy?

[crazyrobinhood]

That's the output when I plug adapter from teensy side:

Code: Select all

I'm going to try this from mini laptop with ubuntu.
Thanks for your help!


EDIT: same device descriptor read/64 error also from mini laptop with ubuntu.

The operating system does not recognize the fake Teensy board.
The USB cable or/and the fake Teensy may be defective.

[crazyrobinhood]

Ok, so I have to guess that the board is defective...
Do you have some well known places where to order a genuine teensy? ( I live in italy )

THank you very much for your support and help!
And thank you for your hard work!

EDIT: nevermind, I found the link in the adapter description page.
thanks again.
