Description

What are the mode pins (SW6) settings needed to boot from an SD Card on different revisions of the Zynq UltraScale+ MPSoC ZCU102 Evaluation Kit?

Solution

(UG1182) Table 2-2 shows the DEFAULT mode SW6 settings (selecting QSPI32 for boot mode) as shipped:

Table 2-4 documents the ZCU102 mode SW6 optional settings, allowing SD to be selected for booting, and will be updated in (UG1182) v1.2 for ZCU102 Rev 1.0 boards to the following:

HeadStart and Revision D ZCU102 boards require the following SW6 settings to select SD mode:

SW6[4:1] = MODE[3:0] = [0101 for SD]

Revision 1.0 ZCU102 boards require the following SW6 settings to select SD mode:

SW6[4:1] = MODE[3:0] = [1110 for SD]

 The polarity of the SW6 switch is ON = pulldown, OFF = pull-up, as shown in Table 2-2, (UG1182) v1.2.
