@walterpre, @BigEyetuna & @jacky4566 : jetty840 identified the issue with the SST26 series and its been fixed with v3.3.0.
@Srmojo & @timoteo_mendes: I've just tested the latest version of the library - v3.3.0 - with the W25Q64JV on the Adafruit 328p feather and it works fine. I do not have an Adalogger handy, but AFAIK, the both of them use the same µC - hope it helps!
@amirezz: There was a bug in v3.2.1 that prevented the library from writing to the SST25 and SST26 series. This has been fixed in v3.3.0. Also, the library supports the LE25U40C.
@zhliao: Could you check and confirm that v3.3.0 also causes the same issue? If it does, please let me know and I will take a look at it right away.
