- azonenberg 2y agoYeah but again, we're talking about the FMC here not the OCTOSPI. Have you hit issues with the FMC? From what other people are telling me, the OCTOSPI is full of land mines and the FMC is pretty decent. The worst errata I've encountered so far is two dummy clocks with CS# asserted at the end of a read burst.
- syntheticgate 2y agolol, I'm working on an FMC-FPGA interface at work right now and discovered this same chipselect behavior.
- azonenberg 2y agoIt's a documented errata, 2.6.1 on page 8 of ES0491.
