7.11. Intel Agilex3 SoCFPGA

Agilex3 SoCFPGA is a FPGA with integrated quad-core 64-bit Arm Cortex A55/A76 processor.

Upon boot, Boot ROM loads bl2 into OCRAM. Bl2 subsequently initializes the hardware, then loads bl31 and bl33 (Linux/Baremetal/Zephyr/FreeRTOS) into DDR and boots to bl33.

7.11.1.1. Code Locations

Trusted Firmware-A: link

7.11.1.2. Build Procedure

Fetch all the above 2 repositories into local host. Make all the repositories in the same ${BUILD_PATH}.
Prepare the AARCH64 toolchain.

make CROSS_COMPILE=aarch64-linux-gnu- device=agx3

make CROSS_COMPILE=aarch64-linux-gnu- bl2 bl31 fip PLAT=agilex3

7.11.1.3. Install Procedure

dd fip.bin to a A2 partition on the MMC drive to be booted in Agilex3 board.
Generate a SOF containing bl2

aarch64-linux-gnu-objcopy -I binary -O ihex --change-addresses 0x00000000 bl2.bin bl2.hex
quartus_cpf --bootloader bl2.hex <quartus_generated_sof> <output_sof_with_bl2>

Configure SOF to board

nios2-configure-sof <output_sof_with_bl2>
