  1. Hi, Im trying to catch an interrupt from an AXI GPIO switch from my board ZCU102. I have created the following design in Vivado: The design is validated so now im using Petalinux to boot linux. I have exported the .hdf file and built petalinux but i can't boot linux.It hangs after that: Exit from FSBL NOTICE: ATF running on XCZU9EG/silicon v1/RTL5.1 at 0xfffe5000 NOTICE: BL31: Secure code at 0xfffc0000 NOTICE: BL31: Non secure code at 0x8000000 NOTICE: BL31: v1.2(release): NOTICE: BL31: Built : 17:17:47, Dec 1 2016 [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 4.4.0 (tecnobit@TBL241) (gcc version 4.9.2 20140904 (prerelease) (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) ) #2 SMP Thu Dec 1 17:19:05 CET 2016 [ 0.000000] Boot CPU: AArch64 Processor [410fd034] [ 0.000000] earlycon: Early serial console at MMIO 0xff000000 (options '115200n8') [ 0.000000] bootconsole [uart0] enabled [ 0.000000] cma: Reserved 128 MiB at 0x0000000078000000 [ 0.000000] psci: probing for conduit method from DT.

Any idea?? pl.dtsi zynqmp.dtsi pcw.dtsi system-top.dts system-conf.dtsi
