I noticed that the MMC Compatibility page says there is no SD card driver support in u-boot. But isn't the boot device onboard strata flash for both BasicX and Connex? Why then does it matter if u-boot supports SD? Can I boot from strata flash and use SD card instead of MMC? Does the current kernel have SD card support? -- Doug |

If you wanted to put a root_fs image on SD, boot into u-boot, and re- flash the image. > Can I boot from strata flash and use SD card instead of MMC? nope > Does the current kernel have SD card support? nope, last I read you had to buy a driver from someone... |

I am using them all the time. (See gumstix-buildroot/sources/kernel-patches/000-gumstix-sd-card-support.patch) You only need MMC cards for reflashing from u-boot because of the missing SD card support there. But for SDIO you currently have to buy a driver: http://www.gumstix.org/tikiwiki/tiki-index.php?page=Third%20party%20products Ralph |
