Hello everybody,
I think this is an off topic post but it's a while I'm googling for this
subject and I cannot find any useful information.
This is my question:
I would like to use an eMMC card on the board. So it is soldered on the
board and directly connected to the IMX53. I think the same is for flash
or other non volatile memories...
How do you first program them with u-boot and linux/android for the
first boot?
Thank you to everyone who want to share the way they operate or some
best practice link.

Thank you Otavio, Gary, Fabio for your replies,
I'm a bit confused about the mfgtools, I'm trying to find a windows
computer to test. My laptop comes with windows 8 preinstalled and the
program crash when I try to select the USB port. On all the other
computers I have linux installed.
Regarding the various solution with u-boot. The part that is not clear
to me is: I need to have u-boot on sdcard otherwise the imx53qsb doesn't
boot. Where do you place u-boot? On a USB drive? I saw on the datasheet
that I can use eMMC, SD and NAND or Hard Disks via PATA/SATA. USB is not
in there.
In this case, I'd elect to build a bootable SD card (you can do
this directly in your Yocto build) which can then be used to
format the eMMC, install the file system and U-Boot. It will
be a two stage process but it will work on a raw board. Once
you get the eMMC formatted and filled, it should just be some
jumper/switch settings to boot from eMMC instead of SD.
Note: most of the other replies have been with i.MX6 in mind.
My question is: When I have a brand new board with the eMMC memory
soldered on. How can I install there u-boot and all the rest of the
system? I can't make u-boot install anything, because it's not there
yet.
Can someone explain it better?
Thank you again
Andrea
