Zynq-7000 PS(a9) is emulated by qemu-system-aarch64 QEMU binary. Most common command
line switches of PS are captured in qemu_args.txt.
| Switch Name | Value | Description | Source of the Config | How to Extract the Info |
|---|---|---|---|---|
| -M | arm-generic-fdt-7series | Indicates the QEMU machine to create.
arm-generic-fdt-7series tells QEMU to parse dtb
for machine generation, passes by -hw-dtb
user.dtb. |
Static | Hard coded for Zynq-7000 devices |
| -serial | -serial /dev/null -serial mon:stdio | Redirect the serial port to specified char dev (i.e., stdio, tcp port, file, etc.) | Based on the UART configuration of the Zynq IP. |
Zynq-7000 has two UARTs. When enabling
UART0:
Then specify: When enabling only UART1:
