File corruption when transferring a file from SD card using FTP

Question asked by RobertCraig on Aug 5, 2013

I'm using the 2010R1-RC5 release with the 2.6.34.7 kernel release on a  BF518F processor.  The application is a pretty standard implementation  with an SD card connected to the RSI lines and inetd used to execute  ftpd sessions for uploading / downloading files. I've found that when I download files, I occasionally get files with 4-8 bytes corrupted one or more times and was wondering if this is a known problem.  The one common note to the corruption is that it always seems to occur towards the end of a 4K (0xFF?) boundary in terms of file position, almost like the end of a buffer is being overwritten.

 

e.g. at

0x087BDFF4

0x00E76FFC

0x012A2FFC

0x0986BFF8

0x0AA34FF8

0x0D46FFFC

 

Any help would be appreciated.
