Title: IRToyV2 fails to create a COM port
Post by: domi on June 28, 2013, 03:59:19 pm
I have been using the IRT for a while.

I was sending some bytes with RealTerm. As usual, when no response came any more (e.g. Widget Mode) I disconnect the IRT from its USB connection and reconnect the IRT.

Although at reconnection the PC (WinXP) gave the  dong-ding reconnect sound, the COM port had disappeared. The Led of the IRT remains on. I did it several times with the same result.

I went to a previous XP restore-point, and my COM port of that time also didn't show up.
I went to the fw_update procedure. Jumpered PGC and PGD. Although not giving any COM port because it didn't exsit, the firmware was reloaded.

Stil the first deconnection(ding-dong)/reconnection(dong-ding) didn't made the COM port show up and the LED remains on.
The second deconnection/reconnection time I was too happy seeing again the missing COM port showing on my XP.

 Question:
What is the reason the IRT LED remains on, which was tha cause that the COM port never was created.
Was the fw-restore the only way to ged rid of that problem?

I tried to fw-update the IRT with USBIRToy_irW.hex.  It failed.
I tried to re-flash the IRT with V22 (PGC/PGD shorted), it fails too.
The following shows the fw-update dialog:

  Enter Com Port Number 15
  Once the device has entered boot loader mode
  Press any key to continue . . .
  U2IO flash erasing: FAILED.
  Device is not found.
  Operation aborted.
  Press any key to continue . . .

When connected to the host USB, the LED on the IRT remains on...

So I installed USBPcap 1.0.0.4 in combination with Wireshark, open USB tracing tool and tried to fw-update once more.
Wireshark tells the host receives Malformed Packets. Most likely, because of this the host is unable to Flash even with PGC/PGD shorted, and could explain why the host did not proceed or refuses to associate a COM port to the IRT as encountered last time (see previous message).

This situation is critical as my IRT seems dead. Help!


Is the IRT Dead?

All the problems went away after rebooting the Windows XP.

Hi, I have similar problem. But reboot WIndows does not help.

My IR Toy v2 stuck on bootloader mode. The LED keeps lights on.
Device Manager shows a COM PORT but with icon yellow exclamation mark.
I had tried to run "update-USBIRToy.v22.bat" on both WIndows XP and WIndows 7.
I entered the correct COM Port number. But it return the same result as below:

Enter Com Port Number 3
Could not open com port.
Once the device has entered boot l
Press any key to continue . . .
U2IO flash erasing: FAILED.
Device is not found.
Operation aborted.
Press any key to continue . . .

I had also tried using jumper to short PGD and PGC pins, it gives the same result as above. Could you please guide me on this? Your generous help would highly appreciated. Thanks in advance.

The yellow exclamation mark tells there is something wrong with the COM port.

Have you trid to re-install the driver? Maybe go back to previous restore point and start overr again ...

I have had the same problem and bricked two brand new IR Toys. Once they go into bootloader, Windows no longer sees them as COM3, so there is no way to connect to them to actually update the firmware. There is no help for this total shit product. Buyer beware. I am so pissed off about this horseshit.
