Target ``mrvl_uart`` produces GZIPed TAR archive ``uart-images.tgz.bin`` +with either three files ``TIM_ATF.bin``, ``wtmi_h.bin`` and ``boot-image_h.bin`` for non-secure +boot or with four files ``TIM_ATF_TRUSTED.bin``, ``TIMN_ATF_TRUSTED.bin``, ``wtmi_h.bin`` and +``boot-image_h.bin`` when secure boot is enabled. + +Compilation: + +.. code:: shell + + > git clone https://github.com/MarvellEmbeddedProcessors/A3700-utils-marvell.git + > make -C A3700-utils-marvell/wtptp/src/Wtpdownloader_Linux -f makefile.mk + +It produces executable binary ``A3700-utils-marvell/wtptp/src/Wtpdownloader_Linux/WtpDownload_linux`` + +To download images from ``uart-images.tgz.bin`` archive unpack it and for non-secure boot variant run: + +.. code:: shell + + > stty -F /dev/ttyUSB<port#> clocal + > WtpDownload_linux -P UART -C <port#> -E -B TIM_ATF.bin -I wtmi_h.bin -I boot-image_h.bin + +After that immediately start terminal on ``/dev/ttyUSB<port#>`` to see boot output. + +CZ.NIC mox-imager +~~~~~~~~~~~~~~~~~ + +CZ.NIC mox-imager supports all Armada37x0 boards (not only Turris MOX as name suggests). It works +with either with separate files from ``uart-images.tgz.bin`` archive (like Marvell Wtpdownloader) +produced by ``mrvl_uart`` target or also with ``flash-image.bin`` file produced by ``mrvl_flash`` +target, which is the exactly same file as used for flashing. So when using CZ.NIC mox-imager there +is no need to build separate files for UART flashing like in case with Marvell Wtpdownloader. + +CZ.NIC mox-imager moreover supports higher upload speeds up to the 6000000 bauds (which seems to +be limit of Armada37x0 SoC) which is much higher and faster than Marvell Wtpdownloader. + +Compilation: + +.. code:: shell + + > git clone https://gitlab.nic.cz/turris/mox-imager.git + > make -C mox-imager + +It produces executable binary ``mox-imager/mox-imager`` + +To download single file image built by ``mrvl_flash`` target at the highest speed, run: + +.. code:: shell + + > mox-imager -D /dev/ttyUSB<port#> -E -b 6000000 -t flash-image.bin + +To download images from ``uart-images.tgz.bin`` archive built by ``mrvl_uart`` target for +non-secure boot variant (like Wtpdownloader) but at the highest speed, first unpack +``uart-images.tgz.bin`` archive and then run: + +.. code:: shell + + > mox-imager -D /dev/ttyUSB<port#> -E -b 6000000 -t TIM_ATF.bin wtmi_h.bin boot-image_h.bin + +CZ.NIC mox-imager after successful download will start its own mini terminal (option ``-t``) to +not loose any boot output.
