HPS GPIO's ouputs stuck in high impedence?

Hi kyle,

Thanks for your reply.I am just a starter in deo nano SOC board.My req is very simple I just wanted to access all the GPIO pins GPIO1 and GPIO0 .since I did it using the C code with HPS_LED and HPS_key I thought I just have to use the existing .SOF.But then since this did not work I generated own .SOF using system builder.But since this said no driver found I had to use qsys tool.This is where I got stuck.I just need a .sof where I can confiure the register and do the toggling and clearing.thats the requirement.so can I use the existing HPS_LED.sof and in that modify the .V file and add the

.hps_0_hps_io_hps_io_gpio_inst_GPIO01 ( HPS_GPIO_1 ), // .hps_io_gpio_inst_GPIO01

will this eneble the GPIO1 and can I access the register from the linux user space.??

Need to generate .sof to create this

Kindly let me know.

Thanks and regards
