14.1 Zynq-7000 Silicon Rev 1.0 - I cannot program the QSPI flash in legacy mode when I boot in JTAG mode


In Zynq revision 1.0 silicon, I am attempting to program (erase/write/read) the QSPI in legacy mode, booting in JTAG mode, but my code hangs.


MIO[5] is connected to the HOLD signal when the QSPI flash is in legacy mode.

To ensure that the HOLD signal is not held Low (causing the QSPI flash to halt the data transfer), enable the internal pull-up on MIO[5].
