No display found

Post by APPAV » Fri Jun 08, 2018 9:53 am

Hello,
I've just receive my first GTT70A-TPR-BLM-B0-H1-CS-V5 screen and I can't connect it with the GTT Designer software.
At the first screen, I choose the GTT70A display and when I click on the detect diplay button, I have the message : No display found
I put the jumper on the middle two keypad pins (row5/col 1), put my USB cable on the Mass Storage plug and power the disaply with 5V power supply. On the screen of my GTT70 I have an USB cable displayed, but nothing on my computer. I use the last firmware and the last GTT Designer sofware.
And I have installed the USB drivers found on your website.
What is wrong ? Do I miss something ?

Hi APPAV,

Welcome to the forums!

I understand you're experiencing difficulties connecting your GTT to the GTT Designer. It sounds like you're currently running the newest GTT Designer revision, and you've updated to the latest GTT firmware. Have you updated your GTT's bootloader as well?

The bootloader contains setting configurations that are important during startup. These settings also ensure that the proper information is returned to the GTT Designer upon request.

Our most recent Bootloader is R1.6.0.8950. You can download the latest bootloader here.

Cheers,
Daniel Divino

Hi Daniel,

Thank you for your answer and you are right, I havn't installed the last bootloader. But the problem is the same. The designer software doesn't detect my display.
In the mass storage mode, when I power up the display, I have the USB cable displayed on the screen but when I plug my USB cable in the display, may I see an new device in my PC? I don't see any change in my control panel in my USB controler.
I've already tried to change my USB cable, and I reboot my PC.
My version of Designer is the v1.12.0.10123, the boot loader is R1.6.0.8950 and firmware is R2.10.0.9823.

Do you have any ideas?

Regards,
APPAV

Hi APPAV,

What happens when you connect your GTT to your PC via the Mass storage header while in regular operating mode (Mass Storage jumper removed)? The GTT should appear as a "GTT Bulk-IO Device" under Universal Serial Bus devices in Device Manager.

Daniel

Hi Daniel,

Nothing happens at all. No new device under Universal Serial Bus devices. Even not the refresh state of the list of devices when I connect something on my computer. I've tried on all my USB ports of my computer, with 3 differents cables.
Is there something wrong with the drivers installed on my computer ?

Regards,
APPAV

Hi APPAV,

I've consulted one of our engineers regarding your issue, and it sounds like the issue might be caused with the drivers Windows supplies. Windows should automatically come with WinUSB drivers allowing the GTT's Mass Storage mode to be automatically detected, but in the past we found that certain PC's are not equipped with these drivers.

You can use a program like Zadig to install these WinUSB drivers on your PC. You can download the zadig program here: https://zadig.akeo.ie/
I suggest you try using this program and attempt to download/install the most recent WinUSB drivers on your PC.

Cheers,
