GPIO leds pin not changeable

cascade99
cascade99 over 7 years ago

Hi, I followed "The Zynq Book Tutorials for Zybo and Zedboard" to create gpio_leds and gpio_btns,

download image to zedboard, I'm using petalinux/vivado 2015.2, I saw there were two gpiochip 902

and gpiochip 906, I did:

echo 902 > export

echo out > direction

echo 1 > value

I tried on both 902 and 906, the leds didn't turn on and off.

Anybody knows why?

 

Thanks

    Please do not continue to post duplicate copies of the same question on multiple forums on the site. This just creates more work for those who would spend the time to work on your question.
