Error Connecting STPMIC25 GUI with USBI2C bridge

hi team,

I'm facing issue connecting stm32mp25 gui tool with the STEVAL$USBI2CFTA bridge, the GUi tool says No bridge connected.

I still haven't connected the other end of the USBI2C bridge to PMIC stpmic25a.

I have installed the required FTDI 260Q drivers, and also the FTDI testing software which detects the usbi2c bridge and im able to send the i2c messages and detect the slave, but the STPMIC25 GUI says no bridge connected.

FYR im using windows 11.

Hoping for a quick reply for this issue. Thanks in Advance.

Hello sanjaysb,

 

The STPMIC25 graphical user interface (GUI) operates exclusively with the STEVAL-USBDNGV1 interface, which is included in the kit STEVAL-PMIC25V1.
