NXJ is ticking and can't power on

[s.frings]

The Mindstorms device does not call itself "GPS Camera". So if your operating system shows that name, the bluetooth settings of Windows are obvisouly broken. I would try to reinstall Windows or use another computer and then retry.

I think my NXT is hosed, yours may be too if you have all the following symptoms:

- you plug it into windows and the device driver recognizes a 'new' device 'GPS Camera Detect' product that is made by 'Wonde Proud'.
- you plug it into linux and using the command 'lsusb' you see a new device 'Atmel Corp. at91sam SAMBA bootloader'.
- youve tried libnxt's fwflash utility in linux to no avail.
- youve tried the sam-ba_cdc_2.8.linux_01 utility in linux to no avail.

Anyone else have other (linux or windows) favorite utilities to flash the firmware?

Hi,
Hmmm that does not sound good. However the device is showing up correctly on Linux, so I'm surprised that you are not able to flash it from there. Have you ever been able to flash the device from your linux system? If not perhaps you just need to adjust some of the settings. On Windows do you have the Lego drivers installed? Can you find and delete (or at least disable) the camera driver that is being recognised and then try again....

That one time, I chose "search for drivers online" and windows downloaded some drivers from windows update. After that, the NXT was called "GPS something" - maybe it was that camera too.

Update: I can confirm this! Today, I bootet my old Windows 7 installation which detected the NXT (in firmware update mode) as "GPS Camera Detect (COM12)".

I would recommend, that the person who has the problem installs the Lego drivers. You then may have to right click the device in the device manager, then chose "update driver" and switch to the lego drivers manually.

With the wrong drivers, you wont be able to flash the device.

The even better method is to install the Lego drivers before you connect the NXT for the first time.

Hi all

Have all of you tried on linux?

hello, im back! :p the reason is this:
I finally repared my nxt !!!!!!!!! I never was so happy to hear that startup sound again!!!!!!!!

═════Here is how i did it:════════════════════════════════════════════════════════


Details:
-done with Windows 7 32 bit Ultimate
-also using NXT-G 1.0
-installed all the drivers i could need for this (download here)

Problem
My NXT is ticking after i tried to install LeJos Firmware. If i plugged the NXT in my computer via a usb cable, my computer named him 'GPS Camera' or something. Whatever i do, nothing happened, just stays ticking. If i hold down the button on the back in the upper-left corner, he stops ticking for a while, then gives a loud click, and continues ticking. The only way to stop the ticking is putting the batteries out of it.

my Solution
First, Download the latest NXT firmware here.
Copy the file inside the zip to your desktop.

Then, plug your NXT in your computer using a USB cable.
Wait until your computer recognises him, then go to your 'Devices' or something. Right-Click your NXT ('GPS Camera' or something) and select properties. then go to the tab hardware, and click again 'Properties'.

Then select tab 'Driver' and click the second button ('Update').

Next click the second button (NOT automaticly search or something, but search on your computer). Then click again the second button. Select something with '61883' in it, and click Next.

After that, DEselect the option 'Compatible hardware' or something. If its right there have to appear 'LEGO MINDSTORMS NXT'. Select that, and click Next. If he asks something, click yes.

Then you should get a screen that indicates that it has succeeded.



Then startup NXT-G and select from the menu 'extra' and then 'Update Firmware' or something. Select the firmware version you just downloaded and click download. Normally, you should hear the NXT startup sound.

For me it worked, i hope for you too.
