LP8764-Q1: Endless Programming step

Bala Mahadeva iyer

Part Number: LP8764-Q1

The part is already programmed. The GPIO4 is configured as enable. Now when I try to re program the device, I keep GPIO4 = 1'b0. Still the programming takes an aweful lot of time. Now the device will not finish validation. The programming to the EPROM step never finishes.

How can this be overcome ?

Hello Bala,

Can you please update the DFU drivers and get back to me to see if that solves your issue ?

Hello Florian,

Is the DFU driver update for the laptop where I am running the SCalable PMICs GUI or is it for the controller on the EVM ?

I am using WEB GUI method

Hello Bala,

Yes the DFU driver is for the computer you are running the Scalable PMICs GUI on, including web version.

Just download and install the software package and see if it helps.

Best regards,

Florian
