SD_CMD signal phase is opposite that needed by my card. Is there any way to change the 'phase' of the SD_CMD/SD_DATn signals so they are valid on the rising edge of SD_CLK instead of being valid on the falling edge of SD_CLK during card acquire? (CMD0, CMD1, CMD2).</P><P></P><P>I'm running the sd/mmc example code from LPC43xx examples.</P><P></P><P>Windows, Linux, and OSX hosts all use 'phase 0', data valid on rising edge of SD_CLK. Why is the LPC43S57 SD/MMC host opposite?</P></BODY></HTML> Thu, 22 Jun 2017 15:49:10 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC43xx-sd-mmc-card-acquire-fails/m-p/669947#M26797 rickrigby 2017-06-22T15:49:10Z Re: LPC43xx sd/mmc card acquire fails https://community.nxp.com/t5/LPC-Microcontrollers/LPC43xx-sd-mmc-card-acquire-fails/m-p/669948#M26798 <HTML><HEAD></HEAD><BODY><P>I see some discussion on this but didn't try myself:</P><P><A href="https://www.lpcware.com/zh-hans/node/1110550">https://www.lpcware.com/zh-hans/node/1110550</A></P></BODY></HTML> Tue, 27 Jun 2017 17:20:39 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC43xx-sd-mmc-card-acquire-fails/m-p/669948#M26798 Dezheng_Tang 2017-06-27T17:20:39Z
