Two Questions: "Replacing" default start-up program on the ADSP-BF537 EZ-KIT Lite & Communicating w/ ADSP-BF537 EZ-KIT Lite via RS-232

Hi,

I'm new to developing on the  ADSP-BF537 EZ-KIT Lite, and so far I have a couple questions:

1)  Is it possible to write a new VI, load it on to the board and have it run instead of the default start-up program (i.e. cascading LEDs) when the board is powered up or restarted?

2)  Is it possible to communicate to the BF537 via the UART port only?  I have no problems communicating to the board via USB, but when I attempt to establish the same communication between the PC and the BF357 via an RS-232 cable (with the USB cable disconnected), I get an error starting "[VisualDSP++] Failed to connect to processor."  I have been successful in communicating with the board using the UART port after I have downloaded the VI to the board using the USB connection, but I'd like to not have to communicate via USB at all.  All the Enable SWs are in their default positions.

Thanks,

Sean

Hi Sean,

1. See this link.

2. I don't know about only using the UART but you may want to try debugging via TCP.

Thanks Charlie!  Link worked like a charm.

Do you happen to know the name of the .dxe that was originally loaded into the Flash memory?  Though, if I can't find it, I'll just rewrite it.

I have been trying to interface with the board via TCP/IP.   So far so good. I have been sucessful in communicating with my board via the UART port, but only AFTER I've attached to the processor and loaded the VI via USB.  I'm hoping there's a way to do all of that with just the RS-232 cable.
