Hi David, <br clear="all"><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Do you have any ideas why we've seen MMC corruption issues? One thought is that<br>
the kernel is allowing the battery voltage to drop too low before powering down?<br>
<div class="im"><br></div></blockquote><div>If I am not mistaken, you mean inand flash corruption. Sandisk inand datasheet says it work voltage <span class="Apple-style-span" style="font-family: arial, sans-serif; line-height: 27px; ">range<span class="Apple-style-span" style="font-family: arial; line-height: normal; "> 2.7V to 3.6V, Q5/Q7 hardware shutdown system power when voltage under 2.9V. Sandisk response that the iNAND failure is due to write abort which is most likely occurring during write, when the operation is unexpectedly terminate due to the interrupt of power supply to iNAND/Platform. Maybe inand power not stable, but we can't make sure it. </span></span></div>
