Zynq-7000 AP SoC, Boot - Quad-SPI Boot, Image search for dual SS, 8-bit Parallel I/O is performed in 64 KB steps, search range limited to 16 MBs

描述

During Quad-SPI Boot using the dual SS, 8-bit parallelwiring connection, the image search will occur in 64 KB steps instead of 32 KB steps. The search range is limited to 16 MBs instead of 32 MBs (for NOR and dual SS, 8-bit parallel Quad-SPI).

解决方案

Impact: Minor.

Work-around: Align boot images to 64kB boundaries.

Configurations Affected: Systems that utilize QSPI dual x4 boot.

Device Revision(s) Affected: Refer to theZynq-7000 AP SoC Design Advisory Master Answer Record(Xilinx Answer 47916).
