I tried installing android image given on the radxa downloads, but on the u-boot time mmc initialization fails.
After that I tried building the image & I used the given android SDK, image builds successfully but while running the image at u-boot time, I am facing the same issue.
What can be the problem, I am open to make manual changes in uboot and build it my self.
EDIT: I am using PhoenixCard to flash the image
