20 years agoHi,
I realized after I made my original post that I should have more accurately described what I'm trying to do. There will be some data stored on a Compact Flash (CF) that we need to transmit to an external PC as fast as possible using the 100BaseT connection that is installed on the Development Kit. Each of the data files that will be stored on the CF will be approximately 32 MBytes in length. We would like to keep the transfer as simple as possible so the current plan is to perform a simple FTP transfer since the FTP capability is already available in the kernel. I don't know what kind of overhead in incurred when using FTP but even if we pay a little price in bandwidth by using FTP, the overall simplicity is a higher priority. Given that basic scenario, is a "burst" (approx. 4 sec.) transfer rate of 70 Mbps realistic? Can uClinux and/or the CF card even transfer data at 8.75 MBytes/sec. (70 Mbps)? Or is a 20-30 Mbps (2.5 - 3.75 MBytes/sec.) transfer rate more realistic? I appreciate the feedback I have received so far, please keep it coming. Thanks, Brad S.
