Ho im i trouble with uploading my new firmware to DIGI module in -C version (with Jtag).  
The netosprog can discover the digi module but when i try to upload new firmware it always fails on ftp error:

C:  
etos73\bin\>netosprog /upload /firmware=C:\image.bin /mac=auto

NET+OS Programmer  
Version 1.3.13.0

Searching for devices. Please wait…

Locate device (auto): SUCCESS  
Uploading firmware…  
Failed to open FTP session with error 12029

Any ideas what to do? I can update firmware via JTAG and use web uploader, but don want to have web support in my program.
