    HyperFlash - QSPI Flash pin-to-pin compatibility


      I plan to use HyperFlash memory with  my new iMX RT project, but I want to have a possibility to use QSPI Flash instead of it, with shared footrpint. Are there any QSPI Flash memories pin-compatible with HyperFlash? From HyperBus Specification (doc. 001-99253) it seems to be true (page 5, 6), but when I look at QSPI datasheets, everywhere is "DNU" ball in place of signals used by HyperFlash (not "RFU" or "NC", as I hoped).
