When I did it I used LS2088ARDB-PA-DF schematic diagram as a reference. I have a question about level translators for SD card. As I see U205 and U206 (TXBN0304RSVR) and ST6G3244MEBJR is used instead. Will SD card work if I will use <SPAN>TXBN0304RSVR (or TXS02612)? I can't use ST6G3244MEBJR because it have too little&nbsp;BGA pitch. We will use SD card as boot device.</SPAN></P></BODY></HTML> Tue, 08 Oct 2019 06:52:57 GMT https://community.nxp.com/t5/Layerscape/Layerscape-and-MicroSD/m-p/957920#M4747 miha_at_work 2019-10-08T06:52:57Z Re: Layerscape and MicroSD https://community.nxp.com/t5/Layerscape/Layerscape-and-MicroSD/m-p/957921#M4748 <HTML><HEAD></HEAD><BODY><P>*<SPAN style="color: #51626f; background-color: #ffffff;">As I see U205 and U206 (TXBN0304RSVR) are not populated and ST6G3244MEBJR is used instead.</SPAN></P></BODY></HTML> Tue, 08 Oct 2019 06:56:40 GMT https://community.nxp.com/t5/Layerscape/Layerscape-and-MicroSD/m-p/957921#M4748 miha_at_work 2019-10-08T06:56:40Z Re: Layerscape and MicroSD https://community.nxp.com/t5/Layerscape/Layerscape-and-MicroSD/m-p/957922#M4749 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10.0pt; color: windowtext;">The TXBN0304RSVR is used as level translator for SDHC signals on the LS1043ARDB board.
