we need to use the Jetson TX2 TOUCH_CLK - B24 pin as a GPIO output pin. We tried to find information to calculate the GPIO userspace pin number on the Jetson TX2 PINMUX sheet. Unfortunately, we have not been able to find all the required details.
as mentioned above, the problem is that we have not been able to find the details needed to calculate the GPIO number of TOUCH_CLK (port name and port number). As you can see from the attached picture, the details of the GPIO port and port number are not reported in the document.
thanks for your answer. We designed and produced a custom carrier board for the Jetson TX2. Due to an error, our HW engineer used B24 pin instead of B25 pin in its design. Our problem is that we need to activate an external circuit using the B24 pin and, hence, we were looking for a way to drive the B24 pin high.
and search for touch_clk. You will find in the comments it is called touch_clk_pee2 at address 0x0c302000. The “p” not part of the GPIO port naming. ee indicates the port. The number 2 indicates the offset within that port for the GPIO. So you get the GPIO naming EE.02.
