Hi kyle,

If you look at the Pin planner GPIO_1[29] is connected to A8 whereas actually according to expansion headers GPIO_1 [1] AG_28 and user manual PDF.

Bank 4 corresponds to GPIO_1[1] expansion headers which is interpreted in gpio as GPIO_1_D1 .

whereas HPS_GPIO59 is GPIO_1[29] in my pin planner..so how do we ensure both the pins are same..is there any link between bank 4 and bank 7 ??

Kindly help the last mile.

regards

Ravi
