I am now working on FreeRTOS Lab version 150825 to pick up tcp stack in our Zynq application. I found there is some issue when I use ftp protocol to transfer file, where some bytes are corrupted especially when the file is large, for example, when we transfer ~400kB file, the issue occur every time, but it works well all time when file size is ~100B.
I use Notepad++ to open the transfered file and found during some bytes, 4 bytes will be written to NULL like this:
13**:28:54 WARN : [Hsm 55-1559] Software Design already exists with Name D:\BJK\uZED701_bsp\system.mss
13**54 WARN : [Hsm 55-1559] Software Design already exists with Name D:\BJK\uZED701_bsp\system.mss
I found 10 corruptions in file of 400kB size. The issue only occur when transfer file from PC to freeRTOS, but did not find corruption from freeRTOS to PC. Could anyone tell me how to identify the root cause? Thank you very much.
