EK-TM4C1294XL: Generic bulk device driver installation

Part Number: EK-TM4C1294XL

Windows 10; TivaWare_C_Series-2.1.4.178, CCS 7.2, usb_dev_bulk example.

Following lab 11, I got as far as step 4; powering the EK with the user USB port.

When I try step 5, I get an error updating the driver software on the generic bulk device.

This may be the reason why this demo does not run. Let me know how to fix this.

Thanks,

Priya

Hello Priya,

We are working to update the USB driver released with TivaWare to have the correct signing to avoid this issue. I will check on the latest about this and see if I can get an older driver which will work that I can provide you here in the interim.

Ralph,
I am actually using TivaWare_C_Series-2.1.3.156 on windows 10. I am looking forward to the
working files you can send me. When will this be possible?
Thank you,
Regards,
Priya

Hello Priya,

Can you try with TivaWare 2.1.4? There has been some driver issues resolved with that, and perhaps your specific issue will be resolved by using 2.1.4 - please report back after trying.

Ralph,
I tried it with TivaWare_C_Series-2.1.4.178 and I continue to get the same error.
Thanks,
Priya

Hello Priya,

I am following up on some solutions for this issue internally. As soon as I have something concrete I will pass it along to you. I will provide a status update early next week if it is still in progress then.

Hello Priya,

Please download the SW-TM4C-2.1.4.178.PATCH-1.0.zip from software-dl.ti.com/.../index_FDS.html

This patch fixes the error that USB windows drivers were facing with signing. Replace the folder "windows_drivers" of TivaWare v2.1.4.178 with the contents of this patch.

If you are still having issues, make sure the old drivers are completely deleted before updating to the one in patch.
