Thanks for testing.

It seems that this change in U-Boot would fix it:

--- a/include/configs/mx6cuboxi.h
+++ b/include/configs/mx6cuboxi.h
@@ -57,7 +57,7 @@
        "console=" CONSOLE_DEV ",115200\0" \
        "bootm_size=0x10000000\0" \
        "mmcdev=" __stringify(CONFIG_SYS_MMC_ENV_DEV) "\0" \
-       "finduuid=part uuid mmc 0:1 uuid\0" \
+       "finduuid=part uuid mmc 1:1 uuid\0" \
        "update_sd_firmware=" \
                "if test ${ip_dyn} = yes; then " \
                        "setenv get_cmd dhcp; " \

If possible, could you please manually change finduuid in the U-Boot prompt?

=> setenv finduuid 'part uuid mmc 1:1 uuid'
=> saveenv
=> reset

Thanks,

Fabio Estevam
