Hi,
I am using jetson tx2 custom board.
I am currently using usb3(a18, a39,a38) and usb2(a17,b39,b40) with no problem.
Now i need to use another usb2(A19-usb_vbus_en2,B43,B42). how can i enable it on my dts.
I am giving you my curre
Thank you for any help or guidance
Hi,
The design looks invalid since A19 pin is not connected. Please check product design guide:
https://developer.nvidia.com/embedded/dlc/jetson-tx2-series-oem-product-design-guide
Why?our hw engineer used it as another usb.
A19- usb_vbus_en2
B42,B43- usb2_d_p/n
Hi,
Please check
USB_VBUS_EN2(A19) - #2 by Trumany
Ok,
So which pins i can use if i want to enable another usb2?
Listen,
My hw made me this.
He gives Tv constant power to a19.
What i need is to declare in dts this 2 pins: b42,b43 (d_p,d_n).
Hi,
You can use either GPIO pin as the VBUS enable pin. Please refer to product design guide.
In the dts i found that: a17-0xac,a18-0xad,…
How to find the reference for B42,B43…
Hi,
Please do not use the dts which converted from dtb to trace code. You will just see lots of hex values but not something human-readable.
Please download the source code from l4t archive website and use source code to track.
