If it is single wired, then I suggest a work around like the one attached.</blockquote><div><br></div><div>We have MOSI, MISO datalines connected and the workaround is working for us.</div><div>But I just wanted to check if anybody got dual mode working with MX25L25635F,</div><div>and what would be the right fix for it in spi-nor.</div><div><br></div><div>Thanks,</div><div>Shakeeb</div></div></div>
