Lost a byte of data

GNU Radio

Hi all,

I have been using gnuradio to receive the data from the front end
hardware. I have made a file sink to see the data. And the data pattern
seems to lose a byte , and this occurs every 1024 bytes. I think the
software reads 16KB of data but the error comes ever 1KB. I am using a
SSRP module to interface with the hardware, in Ubuntu Gutsy. I have
attached the portion of the file where the change occurs. The unexpected
byte error comes at 5113444.

Any suggestion is of great help.

Sorry, I don’t know of anybody else using an SSRP.

Do all SSRP’s do this? You may want to start with the schematics,
then look at the FX2 firmware, and from there to the host library.
