hello, arm expert.
I am try to run zephyr-os on FVP(qemu_cortex_53), and when I using uart_pl011, I cannot receive the uart signal on the system. For testing the code, I run the same code on qemu_cortex_a53 platform, and it can work well, So I guess that is there any addition fvp configuration I need to do to make the uart_pl011 can produce interrupt signal correct. Below is my fvp parameters:
-C bp.secure_memory=0 -C bp.refcounter.non_arch_start_at_default=1 -C bp.pl011_uart0.out_file=- -C bp.pl011_uart0.unbuffered_output=1 -C bp.terminal_0.start_telnet=1 -C bp.vis.disable_visualisation=1 -C bp.vis.rate_limit-enable=0 -C gic_distributor.ARE-fixed-to-one=1 -C gic_distributor.ITS-device-bits=16
Thanks, waiting for your reply!
