Standalone usrp2 - using SD card

Hi, all.

I want to configure a stand-alone USRP2 transmitter (without using PC,
with SD card).
So, first, I used the “tx_standalone.c” file at usrp2/firmware/apps.

Here are my questions:

  1. Is using the “tx_standalone.c” to configure a stand-alone usrp2 TX
    right way?

  2. Now, does “tx_standalone.c” work?

  3. IF USRP2 works with a “unmodifed” tx_standalone.c, what effects does
    USRP2 have? In example, xxMHz tone generation, etc.,

Thanks.

tx_standalone was early test code. I don’t know if it works anymore.
I doubt it, since it’s not getting built in the Makefile.am.
When it did work, it sent a constant value into the TX DSP pipeline.

tx_standalone does not do what you think it does. We used it for
testing purposes. If you really want to make a complete standalone
transmitter you will likely need to modify the FPGA as well.
