Hi Dongjin Here are two different firmware files you can try: /cfs-file/__key/communityserver-discussions-components-files/68/Older_5F00_Trigger_5F00_Fix.zip /cfs-file/__key/communityserver-discussions-components-files/68/Newer_5F00_Trigger_5F00_Fix.zip They will be used in place of the original file which should be in this folder: C:\Program Files (x86)\National Semiconductor\ WaveVision5 \hardware\fpga_images The original file name will be " adc10d1000 _xc4vlx25_adc10d1000rb.bit" Rename the original file to " adc10d1000 _xc4vlx25_adc10d1000rb.bit.bak" and then copy the new file to be tested into that folder. Let me know if either of both of these work. Best regards, Jim B
