Hi,

Can someone confirm if hardware strapping is required for JTAG pins?

In datasheet it is mentioned that JTAG TDI, TMC, and TRST# signal has fixed 50k internal pull-up resistor and TCK has fixed 10k pulldown resistor

Thanks,

Menaka

Hello Menaka,

I can confirm that CX3 doesn't need any external hardware strapping on the JTAG pins.

As mentioned in the datasheet, the JTAG pins: TDI, TMC, and TRST# signal has fixed 50k internal pull-up resistor and TCK has fixed 10k pulldown resistor.

Regards,

Yashwant
