USB Flash memory

[Armen]

Hi all,

how I can implement an USB flash memory in cRIO 9082 RT system. I need a programmatic access to save and read files to/from flash disk.

Thanks in advance...

Howdy Armen, 

Once you've inserted the USB Flash device, it can be written to like a standard harddrive. USB device will receive a specific drive letter which you can use to address it with the standard File I/O VI's. Be aware of a couple things, 

• The USB device must be formatted for a FAT or Reliance file system. The VxWorks operating system cannot enumerate NTFS. 

• The 9082 BIOS allows you to detect the USB device but not mount it during normal operation. You must install USB software support to the target in order to write to it during operation. This KB will help you with that process: http://digital.ni.com/public.nsf/allkb/86AB0983A974808986257995003F7611

There are a couple code sets on the community that I recommend, 

Save to USB Flash Drive on cRIO

Check USB Flash Drive Memory on cRIO

Check if a USB stick is present on your cRIO

I hope this helps. Let me know if there is anything else I can expand on for you.
