<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have the code built and running on a Raspberry PI. Unfortunately, the target part I am trying to program is a Micron N25Q256. I don’t see that part in the list. When I execute the program with –VV it seems to scan lots of devices.
I see activity on CLK, CS, MOSI with an oscilloscope. But MISO remains logic low. When the program terminates, it just tells me No EEPROM/Flash device found.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Stupid Noob Questions:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]> Is the static level on MISO to be expected? Or should it at least toggle?<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]> Is there any hope with this device? Can I perhaps force it to think the chip is smaller?
<o:p></o:p></p>
<p class="MsoListParagraph"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for any help or suggestions.<o:p></o:p></p>

<p class="MsoNormal">----- Steve<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">P.S. This device is not on a production Motherboard. It is on an ARM processor board that we are developing. The board is a new design that will not boot. I am attempting to program this SPI EEPROM to at least get into a UBOOT environment.
