With FPGA using an external SPI flash (*xilinx*, *lattice ECP5/nexus/ice40*, *anlogic*, *efinix*) option ``-o`` allows
one to write raw binary file to an arbitrary adress in FLASH.
Detect/read/write on primary/secondary flash memories
=====================================================
With FPGA using two external SPI flash (some *xilinx* boards) option ``--target-flash`` allows to select the QSPI chip.
To detect:
.. code-block:: bash
openFPGALoader -b kcu105 -f --target-flash {primary,secondary} --detect
To read the primary flash memory:
.. code-block:: bash
openFPGALoader -b kcu105 -f --target-flash primary --dump-flash --file-size N_BYTES mydump.bin
and the second flash memory:
.. code-block:: bash
openFPGALoader -b kcu105 -f --target-flash secondary --dump-flash --file-size N_BYTES --secondary-bitstream mydump.bin
To write on secondary flash memory:
.. code-block:: bash
openFPGALoader -b kcu105 -f --target-flash secondary --secondary-bitstream mySecondaryBitstream.bin
