Help with ATMEGA32u2 –
I have just flashed my ATMEGA32u2 board with the Teensy 1.0 hex file and the flashing process went fine. After I press start application, it disconnects and reconnects to say usb device not recognized--should it say this? Because I have tried five times now and it is not working with my PS3. The LEDs do not turn on and nothing seems to be happening. Please help. Thank you.
Using Atmel's FLIP (I assume you use this tool), when you press START APPLICATION on PC it will do nothing, so don't worry.
If everything's ok, plug the board to PS3, press PWR, EJECT and wait...
Which teensy hex did you use? The one with AT90USB162(the same pinout as ATMEGA32U2) chip I hope?
Also make sure that you don't have HWB pin connected/soldered to GND (pure or via res), as the low level ('0') is needed ONLY when flashing your avr on pc activating chip's bootloader on start - NOT your app. AFAIK some teensy boards have HWB connected to gnd (via res), which will always jump to execute HalfKay bootloader...
I'm having the same issue..
Windows 7 x64, using Flip 3.4.2.
When I try to detect the USB board, I get a Usb not recognized error from Windows.
I already have the x64 USB signed drivers installed.
What can I do?
I had problems on vista x64, try to flash it using a pc with xp.
already tried with an clean WINDOWS XP SP3 32 bits, and get the same error :s
try plugging it in, then pressing one of the buttons. I believe one of them puts the chip into program mode or something. then whenever it asks to install the driver, direct it to the usb folder in the Flip directory.
Have you tried to use Teensy.exe ??? http://www.pjrc.com/teensy/loader.html
Before using Teensy.exe uninstall the driver for the ATMEGA32u2 board or else windows will constantly interfere with Teensy process. The board has it's own software on it and does not need a driver installed. Deny any windows process trying to install a driver for the board.
1.) Right click Teensy.exe and run as an Administrator. Do nothing.
2.) Plug the ATMEGA32u2 board in and press the button immediately.
3.) In the first box of Teensy.exe click and select your .hex.
4.) Then click the second box.
Hope that helps
Firstly, I used this chip and it works fine so there is no problem with the chip itself. After the flashing process it should disconnect and say usb device isn’t recognised, that’s normal.
Secondly, the led on a development board will only turn on if it is programmed to, so relax it isn’t meant to turn on.
So all you really need to do is flash the chip with the correct hex file (which you seem to have done) using the software on the teensy website. Once you have done this, switch the power to your playstation off at the back or unplug it from the wall. Then connect the chip to the PS3 with a cable (make sure there is no disc in the PS3). Switch the Ps3 on to standby, then power it up and press eject straight away. Then in the XMB you will see an option to install package files.
Now you need to get a USB drive formatted to Fat32, put the backup package file onto it. Connect it to the PS3 and install the package file. Then, your done.
By the way there is a little program on the prjc website to make the LED flash on and off, try flashing it with that first, that will prove if the chip works or not.
any of you guys find a case for your ATMEGA32u2?
