TPS25751EVM: TPS25751EVM Error Flashing to Device

Hi,

I meet same issue. 

3- Ensure that the EVM COM port is connected to the GUI. 

• Go to "Options" --> "Serial Port Settings" --> "Port" (make sure Port selected says "Texas Instruments"

The Port select is "COM3(Microsoft)" as shown below.　Is this the reason for the flash error?

How can this be selected as "Texas Instruments"?

Best Regards, 

Hi Aya,

    Thanks for your reply. The following is our test config file. FYI. Downloads will fail in 70%.

    In addition, could you provide a verified download file for us to test. Thanks a lot.

Hi Aya,

    The PC found port just named USB serial Device. Maybe we missing some USB driver for EVM TIVA MCU.

    Our company maybe have some permissions limit. Can you help to provide the EVM USB driver directly?

Hi Aya,

   I used my PC to re-test the download process is succeed. My own computer is WIN 10 and company PC is WIN 11.Does it matter if the operating system is different? And in my computer the port also says "Microsoft".

Hi Aiden, 

Thank you for the updates.

Could you double check this again?

The Serial Port Configuration should look similar to the image below:

I will get back to you the operating system requirement (if applicable).
