Figure 18: QSPI Flash Programming from an External SPI Master - Signal Diagrams
Warning!
Accessing the QSPI flash directly without putting the MPSoC device into reset may damage the equipped
MPSoC device, as well as other devices on the Mercury+ XU1 SoC module.
3.13 Enclustra Module Configuration Tool
In combination with an Enclustra base board, the QSPI flash can be programmed using Enclustra Module
Configuration Tool (MCT) [17]. For this method, a non-QSPI boot mode must be used during QSPI flash
programming. The entire procedure is described in the reference design documentation, and is only avail-
able starting with revision 2 modules.
Please note that the Xilinx Zynq devices do not support slave serial configuration, therefore only flash pro-
gramming is supported by the Enclustra MCT for the Mercury+ XU1 SoC module.
