    Default write to qspi hangs when application boots from qspi flash

    Altera's DevKit board with EDS 14.0

    bare-metal application reads and writes to/from qspi flash.
    the application works good while loaded from jtag.

    While booted it from qspi flash the application hangs on indirect write.

    Write protection disabled. Any idea?

    Update.
    The write fails due to wrong allocation of SRAM for write.
    It happened only when boot from QSPI flash.
    Use of alt_qspi_sram_partition_set() fixes it.
