Hi there,
I am currently working with Altera De-10 Nano kit board. And here we are using Hps gpio-0,10,13 as output pins.
When we are configuring these pins as output through pin multiplexing we couldn’t drive the pins to high (3.3v) & low (0v).
The state of these pins are stable and not changing when I set the pins through uboot config.
Also Hps Gpio pin - 61,62 are kept as uart pins in target board when I try to configure these pins as Uart they are not working as expected but Hps gpio -65,66 are configured properly as Uart when i set it in pinmultiplexing. Dont know why we are facing this issue while using pin 61,62 as uarts…
I would greatly appreciate if someone advises on the above issue.
Thanks in advance,
Regards,
Ganesh D
