AMD Zynq UltraScale+ MPSoC APU

Overview

This board targets the Cortex-A53 application processing unit (APU) on AMD Zynq UltraScale+ MPSoC devices. GIC-400 for the APU cluster is at 0xf9010000, high DDR at 0x8_0000_0000, and PS UART0 at 0xff000000.

The default console is UART0 (typical Linux name ttyPS0).

Memories

sram0 uses the low DDR window (2 GiB from 0x0).

Known limitations

Only CPU0 is supported by this configuration.

Programming and Debugging

The zynqmp_apu board supports the runners and associated west commands listed below.

	flash	debug

Build (example):

# From the root of the zephyr repository
west build -b zynqmp_apu samples/hello_world

Arm Trusted Firmware (TF-A)

When CONFIG_BUILD_WITH_TFA is enabled (default for this board), the build also produces TF-A bl31.elf under build/tfa/zynqmp/<release|debug>/bl31/. On hardware, Zephyr runs as BL33 after platform firmware (bitstream, FSBL, and PMUFW from the PDI) and TF-A have initialized the PS and provide PSCI via SMC.

AMD ZynqMP boards do not boot from fip.bin. TF-A is built with PRELOADED_BL33_BASE set to the Zephyr load address from devicetree, and the XSDB runner loads the bitstream, FSBL, bl31.elf, and Zephyr ELF separately. When CONFIG_BUILD_WITH_TFA is enabled, west flash passes the built bl31.elf path automatically via --bl31.
