      hello all

       

      I use S25FL512S with STM32,but  I have a problem with REMS cmd:

      when SI output 0x90+0x000000+0x0000, SO can only receve manufacture ID(0x01) correctly and can not receive device ID(0x19);

      when SI output 0x90+0x000001+0x0000, SO can only receve device ID(0x19) correctly and can not receive manufacture ID(0x01);

       

      I have used oscilloscope and found that : the wave of SI is correct, the firse byte of SO is correct and the second byte has no wave,as follows:

       

       

      I want to know where is the reason.

      thank you very much!
