Also, could you do it simply by connecting the data lines together for the two cards and having separate CMD lines for each device?</P></BODY></HTML> Sat, 23 Feb 2013 19:36:09 GMT https://community.nxp.com/t5/i-MX-Processors/i-MX233-and-SDIO-multiplex/m-p/270532#M29128 daveshah 2013-02-23T19:36:09Z Re: i.MX233 and SDIO multiplex https://community.nxp.com/t5/i-MX-Processors/i-MX233-and-SDIO-multiplex/m-p/270533#M29129 <HTML><HEAD></HEAD><BODY><P>Quote from "SD Specifications Part 1 Physical Layer Specification Version 2.00"</P><P></P><P>3.5 Bus Topology</P><P>... </P><P><STRONG><SPAN style="font-size: 10pt; line-height: 1.5em;">Common bus signals for multiple card slots are not recommended.</SPAN> A single SD bus should</STRONG></P><P><STRONG><SPAN class="GRcorrect">connect</SPAN> a single SD card.</STRONG> </P><P>..<SPAN style="font-size: 10pt; line-height: 1.5em;">.</SPAN></P><P></P><P>Regards,</P><P>Jacky</P><P><SPAN class="mce_paste_marker"></SPAN></P><P><SPAN class="mce_paste_marker"></SPAN></P></BODY></HTML> Tue, 26 Feb 2013 07:50:57 GMT https://community.nxp.com/t5/i-MX-Processors/i-MX233-and-SDIO-multiplex/m-p/270533#M29129 JackyAtFreescal 2013-02-26T07:50:57Z Re: i.MX233 and SDIO multiplex https://community.nxp.com/t5/i-MX-Processors/i-MX233-and-SDIO-multiplex/m-p/270534#M29130 <HTML><HEAD></HEAD><BODY><P>Hi David, did Jacky's answer helps you.
