CMSIS: Slow file transfer while using FTP Server example in MDK v5.xx


Information in this knowledgebase article applies to:

  • MDK-MIDDLEWARE Version 6.4.0 and earlier

Question

I was using FTP-Server example based on the old RL-Flash library for LPC1700_DFP in MDK v4.xx and the file transfer speed was around 600-700 KBytes/Second. But, while using FTP-Server example based on new CMSIS-Pack library in MDK v5.xx, the speed of file transfer reduces to 200-300 KBytes/Second. What can i do to improve the speed of file transfer ?

ANSWER

This issue will be resolved in the next release of MDK Middleware Version: 6.5.0

However, this performance also depends on many factors such as the type of memory card (SD Card or MMC), number of files already present on the card etc.
