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.

[Discuss-gnuradio] Lost a byte of data

2008-01-30 Thread Fasika Alemayehu
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.

5113360  f887  fd25   f80b   fd26  f8ad   fdaf   f819   fcd0
 5113400  f83b   fd29  f858   fd3f   f80b   fd7b   f8d2  fe23
 5113420  f92a  fd6d  f7a8   fd83   f89f   fd2e   f800  fd2c
 5113440  f8a3  fd7f   d700  41f7   0bfd   aff8   85fd  adf8
 5113460  9afd  96f8  35fc   aaf8  7cfcbff8   effd   f5f7
 5113500  5afc 93f8   6cfd   5ff8   c9fd   1ef8   4ffd   21f8

Any suggestion is of great help.
