Hi all,

I am using the latest u-boot 2017.05 and built for odroid-u3. However, the
auto-boot fails with the following message Card did not respond to voltage
select! but I can do manual loading and boot and card is all fine. What
could be the problem?

Performing the following set of commands let me boot...

setenv fdt_addr "0x41f00000"
setenv fdt_high "0xffffffff"
setenv vid_config "video=HDMI-A-1:1280x720M at 60"
setenv con_config "console=ttySAC1,115200n8"
setenv rfs_config "root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro"
setenv zimg_file "/boot/zImage"
setenv fdt_file "/boot/dtbs/exynos4412-odroidu3.dtb"
setenv bootargs "${vid_config} ${con_config} ${rfs_config} earlyprintk"
setenv uloadcmd "fatload mmc 0:1 ${zimg_addr} ${zimg_file}; fatload mmc 0:1
${fdt_addr} ${fdt_file}"
setenv bootcmd "run uloadcmd; fdt addr ${fdt_addr}; fdt resize; bootz
${zimg_addr} - ${fdt_addr}"
boot

Any suggestions?
