6.1 License
The VME-PMC-CADDY/2plus module uses the opensource bootloader „Das U-Boot“. The U-Boot
sourcecode is published in terms of the GNU public license (GPL). Please see esd's „3rd party licensor
notice“ document that is part of the product's documentation for the full license text. You can contact
esd for a copy of the full bootloader sourcecode for the VME-PMC-CADDY/2plus.
The U-Boot source is available from esd on request.
6.2 Configuration and Console Access (Serial Interface RS-232)
The default communication parameters are 9600 baud, 8N1 (8 data bits, no parity, 1 stopbit, no
hardware handshake).
After the next power-on you will see the bootloader startup messages on the serial console.
When you see the message 'Press SPACE ....', hit the space key to stop booting and to access the
interactive bootloader console. At the prompt you can use an extensive command set to do
configuration, debugging or testing tasks. Enter help (followed by hitting the RETURN key) to get a
full list of all supported commands.
