The current algorithm that we have does not provide support for 1Gb devices.
We are discussing this issue internally and shall get back to you on this shortly.
Thank you so much for your patience.
Attached is the SLLD source code for S70FS01GS in folder fss_S70FS01GS.zip. It is based on v16.2.1. For using this code, you must implement HAL layer function. The HAL layer example is in slld_v16.2.1.zip.
