3.2.7. Serial Flash Memory Layout

Serial flash devices store the configuration data in sections. The HPS first stage boot loader (FSBL) location depends on the selected serial flash memory layout.

Non-HPS Case:

The following diagram illustrates sections of a non-HPS Agilex™ 5 configuration data mapping in a serial flash device. The non-HPS bitstreams do not include first stage boot loader (FSBL). Refer to Agilex™ 5 SoC FPGA Bitstream Sections of the HPS Technical Reference Manual for more information about flash memory layout for HPS devices.

HPS Case with FPGA First Option:

The following diagram illustrates sections of an HPS Agilex™ 5 configuration data mapping in a serial flash device and the HPS first stage boot loader (FSBL) location when you select the FPGA First option.

HPS Case with HPS First Option and Dual Flash:

The following diagram illustrates sections of an HPS Agilex™ 5 configuration data mapping in a serial flash device when you select the HPS First option.

If you use a third-party programmer to program an .rpd, ensure that the configuration data is stored starting from address 0 of the serial flash device. If you use .jic or .pof files, the Agilex™ 5 Programmer automatically programs the configuration data starting from address 0 of the serial flash device.
