ARM MPS3 User Manual

2.15 User non-volatile memory
The MPS3 board provides on‑board user non‑volatile memory, 8MB QSPI flash (SST26VF064B), 16GB
eMMC16G_M525, and a microSD card interface.
A typical use of the QSPI flash is as boot memory. The microSD card or eMMC memory can be used for
storing the Linux file system.
The following figure shows a non‑volatile memory system example design. For completeness, the figure
includes the DDR4 volatile memory.

Note
The simplest boot method is to use block RAM in the FPGA which can be pre-loaded by the MCC
before resets are released. The use of block RAM requires the FPGA design to implement theMCC-SMC
interface. See 2.7 MCC-SMC interface on page 2-30.
