7.2. AMD Versal Gen 2

Trusted Firmware-A implements the EL3 firmware layer for AMD Versal Gen 2. The platform only uses the runtime part of TF-A as AMD Versal Gen 2 already has a BootROM (BL1) and PMC FW (BL2).

BL31 is TF-A. BL32 is an optional Secure Payload. BL33 is the non-secure world software (U-Boot, Linux etc).

To build: `bash make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 bl31 `

To build TF-A for JTAG DCC console: `bash make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 CONSOLE=dcc bl31 `

To build TF-A with Errata management interface `bash make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 bl31 ERRATA_ABI_SUPPORT=1 `

To build TF-A with IPI CRC check: `bash make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 bl31 IPI_CRC_CHECK=1 `

7.2.1. AMD Versal Gen 2 platform specific build options

  • MEM_BASE: Specifies the base address of the bl31 binary.

  • MEM_SIZE: Specifies the size of the memory region of the bl31 binary.

  • BL32_MEM_BASE: Specifies the base address of the bl32 binary.
