Problems configuring RTDX Host Buffers

Started by Benjamin Sanchez December 11, 2007
Hi all!

I am sending signal's samples from my LabView application to C6711DSK for
computing FFT-radix4. Data transfer works correctly when
the number of samples is equal or less than 128 but If it is bigger then CCS
shows me the following message:

-------------------------
RTDX Detected Error!
An RTDX message was received from the target which will not ft into the RTDX
host buffer.
To avoid data loss reconfigure RTDX so that the RTDX Host Buffers are at
least as large as the largest target-to-host
message and re-run application again.
-------------------------

I have found in the literature how to change the default host buffer size (
RTDX2.0 User's Guide) adding rtdx_buf.c file
in my project and changing the value of the constant BUFRSZ . It should be
enough but when I run again my LabView
program I have the same error!

Any idea will be highly appreciated!

Thanks in advance
