Boot-up support using SD interface

[mrudangshelat]

Hi, I am using iMX6D in my new design and I would like to to boot using SD and eMMC. There are total 4 SD interface available on iMX6D. I just wanted to confirm that can I use all 4 SD interface (SD1, SD2, SD3 and SD4) to Boot-up iMX6D using SD and eMMC? I have also read that "SDR50 and SDR104 boot are not supported on the USDHC1 and USCHD2 ports because there are no reset signals for those ports is connected in the IOMUX." from iMX6 Reference manual. Please provide your valuable view. Thanks, Mrudang

Hi Mrudang

right, one can use all 4 SD interfaces.

For booting one can use High Speed mode, some

overview can be found on p.184 http://cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf
