Part Number: BQ76925EVM
Other Parts Discussed in Thread: BQ76925,

Hi Team,

I try to use USB-TO-GPIO to connect BQ76925EVM. When the bq76925 Evaluation GUI is lauched, the below fault is reported. The USB-TO-GPIO firmware is too old to support.

Where to USB-TO-GPIO Firmware Loader to update firmware? It seems to be unavailable in ti.com.

Hi Dylan,

It seems that another customer faced the same issue here: USB to GPIO - Power management forum - Power management - TI E2E support forums.

Please let me know if the second link/ file provided addresses your issue.

Best,

Andria

Andria,

Thank you. I can download the .bin file. But the firmware loader is unavailable. I have no way to update the .bin file.

Hi Dylan,

Since the website itself does not show a firmware updater, did you take a look at the thread pinned to the page? (+) USB2GPIO-LOADER-SW: Cannot find Firmware - Power management forum - Power management - TI E2E support forums

Additionally, can I confirm that you are using a USB to GPIO, not a USB to GPIO2?

Best,

Andria

Hi Dylan,

Did you take a look at the e2e thread I linked in the previous post? This should provide file locations as well as some general startup info.
