We are trying to stream test pattern from Serializer(DS90UB953), but we couldn't do so, even though we were able to stream the test pattern (visual representation of pattern) from Deserializer(DS90UB954) by interfacing it with Rpi. The test pattern configuration was taken from the datasheet of Serializer(DS90UB953) pg no:32 table.no:7.6.4 code example for pattern generator.
