QSPI Flash
The QSPI flash can be used to boot the PS, and to store the FPGA bitstream, ARM application code and
other user data.
2.16.1
QSPI Flash Type
Table 27 describes the memory availability and configuration on the XU1 SoC module.
As there is one QSPI flash chip equipped on the XU1 SoC module, type “single” must be selected
when programming the flash from Vivado tools.
