Tool/software:

Hello team,

Before we updated the firmware, the DRV8145P-Q1LEVM can be connected to GUI.

However, below message showed up and we performed the update.

After this update, GUI recognize this DRV8145P-Q1 LEVM as a DRV8245S-Q1 EVM as shown below and connection was not able to be established well.

To establish the connection, are we able to recover the firmware to the original one?

Or if you have any other method to establish the connection, please let me know.

Regards,

Hirata

Hi Hirata-san,

Please refer to this FAQ and let me know if this doesn't solve the issue:

Keerthi-san,

So originally they can connect the EVM, but after update the firmware, the connection was not able to establish.
How do you think about this behavior?
Are we able to recover the firmware to the original one?

Hirata

Hi Hirata-san,

Yes, you can. Go to the previous version of the GUI and then program the device.

Hi Hirata-san,

can you tell me what version of the GUI you are currently using? For example, the picture below is 1.0.0

If you are using a more later version then this you can use this link for 1.0.0:

DRV824x_DRV814x-Q1EVM-GUI (ti.com)

and do program device:

It should work with the latest version of the GUI if it worked for a previous one so can they ensure that they applied the external digital supply before attempting to connect to the EVM. Here is the latest in case you want to try this as well with same procedure:

DRV824x_DRV814x-Q1EVM-GUI (ti.com)

Here are what the updates are with each release:

Best,

Keerthi
