We are migrating our design from an S25FL132K part to the S25FL064L part. I'm using the same software for both parts, the latest Spansion SLLD. During initialization, the first thing I do is issue an 0xAB command to ensure its out of sleep, then I issue it again with a 4 byte read. On the S25FL132K part, I receive in MISO 0x00 0x15. On the S25FL064L part, MISO is hard zero. See attached Saleae outputs. I cannot find anywhere specifying why this may not work on the factory S25FL064L part. Please help!
Please let us know which version of LLD you are using. Is it version 16.2.1
