Hello，
One customer used TSB41BA3BTPFPEP+TSB12LV32TPZEP for 1394 data acquisition , during the data acquisition process, the link layer controller DM data loss occurs after approximately 1 hour of continuous collection. Data acquisition can be restored normally after data loss. The 1394 bus data source data that is checked is continuous, .
The following figure is the 1394 data caught by the logic side, the black box is the 1394 data frame coming in from the DM side, the red box is the logical internal frame count, the normal 1394 frame payload data is cumulative. Should be consistent with the logical internal count.
Could you please help to analyze?
Best regards
kailyn
