Hi Kyle,

For the exisiting .v files if I has .hps_io_....GPIO01 ==>GPIO_1 and then compile with qsys and then create .sof then I will be able to access the GPIO1

If I get an example file which has this I can add the same later I can extend this to other pins and repeat the same for GPIO0.

regards

Ravi
