Hello,

i am trying to configure the STUSB4500 on a Eval-SCs001v1 with a F446RE Nucleo board using I2C connection. from my understanding am i unable to use the GUI to make the NVM files because that wont reconize my Nucleo board. Also the example projects are writen for a different boards with different drivers so that wont work either. i have read the documentations but i keep ketting the Hal_ERROR when im trying to make a connection.

i tried to read or write and the HAL_I2C_IsDeviceReady with the 4 different adresses from the STUSB4500 datasheet. i also tried this with and without the bit shift to the left but al 3 end up with no address reconition.

i use 4k7ohm pullup resistors for SCL and SDA. 

im also having the problem that i cant see the signals on my scope whenever im in debug mode, but i do see it whenever its just running so its a bit harder to actively debug the adresses 

 

Any help is much appreciated, thanks in advance.
