1) You have connected a serial connection, not JTAG.

2) Your device is having issues talking to the Camera CCD/CMOS ->

open video device error

That means it couldn't talk to the camera inside the top part.

I do see that the driver did load though  -

Suggest power off for a few minutes, and give it a retry.
Have you done anything like install other firmware on there?

Assuming you haven't, and it still doesn't want to play, then possibly the CCD is broken, or you've perhaps plugged the video into the wrong port.

Looking at the board, there are 3 port connectors on the left side, 2 ports on the right.

The USB connection for the Camera (with the multicolor cable) goes into the first of the 3 connectors. (this is the one closest to the usb wifi daughterboard).
The connection for the Audio, motors goes into the middle connector.
The GPIO sensor is the 3 pin one closest to the network.

If you have taken the camera apart (and it sounds like you have), then ensure that those ones haven't been plugged into the wrong connectors.

Did you read the title of the FIRMWARE section? "Note that firmware is closely tied to what hardware is in your camera. Suggest that you backup your current firmware prior to testing what firmware is compatible with your specific camera hardware!"

If you did not backup the existing firmware prior to installing new firmware, then your camera may be unrecoverable toast.

While there is no guarantee that it is fully compatible with your camera, there is a copy of some original firmware for your model in the FILES section. You now have nothing to lose by installing it.

the problem now is not to find out the right firmware but how to install it in the cam while the cam reboot all the time
i try to press esc to come into bootloader but it will not
i need the right way please and thanks

Are you saying that your camera fails to enter debug mode when you enter ESC during the early part of the boot process?

July 11, 2012, 03:09:57 pm
yes what did i do wrong

If you cannot enter debug mode by entering ESC during the early part of the boot process, then I know of no way to recover via the serial port. At this point your only choice may be in-circuit programming hardware, which is outside the scope of this website.

What did you do? Somehow you have no sh. Maybe you loaded the fs to the wrong location - who knows.

sometimes when ESC is not accepted it shows that either the connection is faulty or the terminal program is not supporting operation without handshake lines (or relevant option wasn't found).

first try to just connect tx and rx pin of the cable to the PC (without connecting to the cam), then every pressed key should appear on the screen.

If this isn't ok, try another terminal software (for linux I suggest minicom, for windows PuTTY).
If it still isn't ok, check the cable.

If the test above is ok, recheck the pinout of the connector to the cam.

btw, you have to be really quick to press ESC ..

Schufti - good catch - he has provided no information to indicate the the Tx of his serial port is functional.
