Hi,

I am trying to build the first tutorial, but cross-compiling for the Zynq Ultrascale+. However, when I run "make E=hello qemu" I get the next output:

Image size(s) in bytes:

Hello from Startup::stage2

Number of IRQs available at this GIC: 192

Assertion failed at /home/jperezu/fiasco/src/kern/irq_mgr_multi_chip.cpp:67: mask

Does anyone know what could be the problem?

I am using CROSS_COMPILE:=aarch64-linux-gnu- to build and ARM64 architecture, ARMv8a CPU variant, Xilinx Zynq Ultrascale+, and CPU Arm Cortex-A53 in the configuration.

Thank you for your help.

Sincerely,

Jorge
