description="ARTIQ flashing/deployment tool",
epilog="""\
Valid actions:
* proxy: load the flash proxy bitstream
* bitstream: write bitstream to flash
* bios: write bios to flash
* runtime: write runtime to flash
* storage: write storage image to flash
* load: load bitstream into device (volatile but fast)
* start: trigger the target to (re)load its bitstream from flash
Prerequisites:
* Connect the board through its/a JTAG adapter.
* Have OpenOCD installed and in your $PATH.
* Have access to the JTAG adapter's devices. Udev rules from OpenOCD:
'sudo cp openocd/contrib/99-openocd.rules /etc/udev/rules.d'
and replug the device. Ensure you are member of the
plugdev group: 'sudo adduser $USER plugdev' and re-login.
* Make the matching proxy bitstream accessible in ~/.migen or
/usr/local/share/migen or /usr/share/migen. Proxy bitstreams are
published at https://github.com/jordens/bscan_spi_bitstreams.
This script will tell you which one is needed.
