    I believe you cannot set hardware BP's but you can set up to 3 software BP's.

    Hi cloud,

    I didn't purchase the FSS license either, but I _can_ set hardware

    breakpoints. Make sure you selected the appropriate option in

    SOPC builder, then use:

    bkpt sethw <addr>

    E.g. a dump from a nios2-console session:

    System Analyzer for Nios® II Processor

    Serial number

    Version 1.9.0 build 9

    cd c:/work/PCI5441/u-boot

    1> halt

    User halt.

    00DEDE00 0xdf000115 stw fp, 4(sp)

    2> bkpt sethw 0

    {0x00000000 hw}

    3> go

    Emulation started.

    Hardware breakpoint.
