I'm using KDS 3.2 with KSDK v2 and a Freedom K64F.

My project works with FatFs, LwIP and stack USB class CDC VCOM


Today I transfer small files(<100kB) by ethernet on the SD card ; TCP / IP guarantees file integrity.

I need to transfer the same files from a pc to the freedomK64 SD : What tool or protocol can I use with USB to ensure the integrity of the transferred files? Are the lwip tools (TCP / IP layer) usable for example?


Thank you in advance for your suggestions
