Valid actions:
* gateware: write main gateware bitstream to flash
* rtm_gateware: write RTM gateware bitstream to flash
* bootloader: write bootloader to flash
* storage: write storage image to flash
* firmware: write firmware to flash
* load: load main gateware bitstream into device (volatile but fast)
* rtm_load: load RTM gateware bitstream into device
* erase: erase flash memory
* start: trigger the target to (re)load its gateware 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.
