Any update on this? This still seems to be the latest IFC6540 commit: https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/commit/66c04e30f4a6e6ed998a6c154a6c45b3cd5b3fde Following the instructions in https://wiki.linaro.org/Boards/IFC6540 I've tried to pass a full rootfs as ramdisk parameter (fastboot boot -c "console=ttyMSM0,115200,n8 rw rootwait" -b 0x0 zImage-ifc6540 initrd.cpio.gz), but I then get: [258660] fastboot: download:12738800 [268150] fastboot: boot [268150] kernel/ramdisk addresses overlap with aboot addresses. Booting without ramdisk specified works, but for lack of SD, USB and network support I then have no root. So, do you have any new insights on why 'status = "okay";' doesn't work for the above sdhci node? Or do you have a working config you can share for creating a non-overlapping abootimg?
