Subject: Xilinx Zynq 7000 Start of CPU1
Date: Wed, 18 Sep 2024 11:13:32 +0200 (CEST) [thread overview]
Message-ID: <1242128488.101916.1726650812387.JavaMail.zimbra@embedded-brains.de> (raw)
Hello,
I recently added the support for CPU1 to the xilinx-zynq-a9 machine (hw/arm/xilinx_zynq.c). However, the reset behaviour doesn't match exactly with the hardware. After a system reset (SRST), the CPU1 should execute a wfe instruction and then load the start address from 0xfffffff0:
https://docs.amd.com/r/en-US/ug585-zynq-7000-SoC-TRM/Starting-Code-on-CPU-1
It would be great if someone has a hint for me how I can add this startup code for CPU1 at address region 0xFFFFFE00 to 0xFFFFFFF0.
Kind regards, Sebastian
