Other Parts Discussed in Thread: TPS65982, TPS65982-EVM

Hello,

I use the booster pack with the TPS65982 as a charger for notebook, and it works well.

But when i connect a USB key directly to the USB_RP_P and USB_RP_N this USB key is not visible from the notebook.

I have connected the R65 & R66 reistors on the booster pack (originaly not connected)

I have attached my config file (config_v0.9.0_app_code.ctb) to this post and also the result of the read_register.py when

the usb key is connected.

any idea is welcome

Thanks a lot

Hi, I apologize for the lack in response. Do you still need support with this issue? If so, please try to re-attach the link to open your zip file (it no longer works).

Did you mean that you connected R67 and R68? These are the pins that are connected to USB2_RP_P and USB2_RP_N on the TPS65982-EVM.

How did you handle the VCC and GND pins of the USB stick? Is this a USB 2.0 stick?

Regards,

Joey
