Hello,
We have created a daughter card for the Ultra that has an AD9361 chip and have added that support into the PL. When booting, the devices drivers detect and initialize the chip and the PL components. However, after logging in the PL IP is in reset. I've discovered that the ultra96-radio-leds.sh is enabling GPIO 511; however, if fabric reset is enabled in the process the this GPIO is connected to pl_resetn and our entire PL is then reset after the kernel has initialized the HW. Clearly this is a problem and I'm just trying to understand the intent here. I can change/disable the script but I'm trying to understand what is going on here.
thanks
jeff
