Valid actions:
|
|
|
|
* gateware: write main 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)
|
|
* 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.
