Problem running the DES example multiple time

FrontPanel
1

Hello,

I compiled the DES example on Linux (Ubuntu) and it seems run well the first time but if I run it again, it fails loading the FPGA image again. However, it seems to be able to talk with the device and grab its interface since it prints the device information.

Here is the log (includes few ‘printf’ of my own)

prompt> ./des_tester e aaaaaaaaaaaaaaaa file1 file2

DES process succeeded!

If I power cycle the board, the DES example works again (for one time, until I power cycle again).

Please visit the following link and download the firmware update. I believe this will fix your problem:

Per your suggestion, I upgraded the firmware from 1.2 to 1.3 and it works well now.

Thanks.
