[resolved] using U-Boot and connect UDOO by serial port ( Still Try Boot android from NFS)

Hi All,
I am the new here.
I have meet an issue for UDOO with Android !
Now, I need boot Android as a clean (initial) status every times, therefore I am trying to find how to make Android boot from NFS.
However, I google it and got this page:

" U-Boot 2013 Released! - UDOO: http://www.udoo.org/u-boot-2013-released/ "
The guides of “how to boot from NFS and SATA using U-Boot 2013″ will be available soon.
Here’s the direct link for the github while all the binary files are available here.

Anyone know where is the guides ? or how to boot Android on UDOO from NFS ?

Thank you very much !!!!

 

I too have spent the past couple days trying to get this to work without much success. I cheated a bit, I wrote the Ubuntu image to an SD card to get U-boot 2013. From there I can boot from a uImage on an NFS share. I can see that it mounts the root file system, but the boot process hangs at "Freeing Init Memory". If I change the androidboot.console to ttymxc1, I can see that it's stuck in a loop of starting services, and untracked pids exiting. I have no output over HDMI; not even the bootanim.

 

Hi there all,
there is no such guide actually.
Cheers

 

Thanks for your answer !
However, is it possible that I can build U-Boot which download from ftp://ftp.denx.de/pub/u-boot/u-boot-2015.07.tar.bz2 to setup the boot option ?
This because I have installed U_Boot 2013 (http://udoo.org/download/files/UDOO_Unico/u-Boot_Dual/u-boot-d.imx) to UDOO which form this guide, but I can't setup anything !
http://www.elinux.org/UDOO_creating..._from_precompiled_binaries#Install_the_U-Boot
screenshot as follow:

As I know, maybe I can use dd to insert the U-boot to SD Card, and then I can setup the boot options which like http://www.denx.de/wiki/view/DULG/LinuxNfsRoot
I need try to boot Android base on U-Boot from NFS !
If it possible, could you please give me an instruction ?

Thank you very much !

 

u-boot-2015.07 can be compiled and works fine.
In 2015.10 version there will be small change to have only one bootloader for both dual and quad board.

 

Th

thanks for your response !

anyone please give an instruction about how to build u-boot for UDOO？
(My goal is boot from u-boot and the setup boot from NFS with Android)

not this page http://www.udoo.org/docs/Advanced_Setup/Compile_Android_From_Sources
build u-boot from_precompiled_binaries !

Also I have Google thsi page: http://udoo.org/forum/threads/uboot-now-has-udoo-support.449/

I have tried these instruction as follow:

Code:

# git clone git://git.denx.de/u-boot-imx.git
# cd u-boot-imx/
# make udoo_defconfig (no quard config)
# make
# dd if=u-boot.imx of=/dev/mmcblk0 seek=2 bs=512 ( no u-boot-q.imx)

# wget ftp://ftp.denx.de/pub/u-boot/u-boot-2015.07.tar.bz2
# tar -jxf u-boot-2015.07.tar.bz2
# cd u-boot-2015.07
# make udoo_quad_defconfig
# make
# dd if=u-boot.imx of=/dev/mmcblk0 seek=2 bs=512 
( no u-boot.imx or u-boot-q.imx only u-boot.bin and u-boot.img )

These two instruction as above which can't boot u-boot on UDOO !

Thanks !

 

I'm only crosscompiling and this instructions are gold: https://eewiki.net/display/linuxonarm/UDOO

 

Thanks for your response. However, I have finish this instructions about u-boot

Code:

wget -c https://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz

git clone git://git.denx.de/u-boot.git
cd u-boot/
git checkout v2015.10-rc1 -b tmp

make ARCH=arm CROSS_COMPILE=${CC}

sudo dd if=./u-boot/SPL of=${DISK} seek=1 bs=1k
sudo dd if=./u-boot/u-boot.img of=${DISK} seek=69 bs=1k

It's still can't boot and HDMI no signal

Maybe I hava make mistake ? UDOO can boot from U-Boot, If I haven't set up and Install Kernel and Root File System ?
I want to boot on U-boot and then tries to use "setenv command" to setup boot from NFS (Android) !

BTW, Many thanks for your great help !

 

Did you compiled u-boot succesfully (you got files SPL and u-boot.img)? You just copy/paste commands from web page but actual result of them is mistery
And do you have serial console attached? You see u-boot messages and you get prompt when you press enter or space?
HDMI is not enabled so nothing is visible at this stage.

 

Thanks again !!!!!

YES ! I have got files SPL and u-boot.img !

Also, I think I really make a mistake that I find these page, now:" Connecting via Serial from Windows "
7.2. Establish serial debug connection with UDOO
http://www.soselectronic.com/a_info/resource/c/S975-G000-2100-C2.pdf

http://www.udoo.org/tutorial/connecting-via-serial-cable/

I have finish these stage, but it's still no any single ! Orz

 

Create one working SD card image to and get your serial console working. THEN try to use your new bootloader.

 

Hi ! Thanks !

Did you mean that I need write pre-compile system image (e.g. Android) to SDCARD and also write u-boot to SDCARD, then boot and connect with serial port ? (is it can setup the u-boot ? if I need use setenv command etc...)

or I only write pre-compile system image (e.g. Android) to SDCARD and connect UDOO by serial port ?

Thank you very much !

PS: I have try to write Android to SDCARD and boot it successes with HDMI, every thing is ok !

 

I'm starting to wonder what you actually wants? You obviously have system already running. Just connect serial console and interrupt bootloader and do what you want.

 

Hi !
I have tried again.
1. only write pre-compileed system image (I use Android) to SDCard, then connect by serial port. (if boot with HDMI is ok)
2. write pre-compileed system image (I use Android) and also write SPL & u-boot.img to SDCard, then connect by serial port.(if boot with HDMI it's no signal)

However, these situation as above both are no signal, if I connect by serial port.

Actually, I want to boot UDOO with u-boot, and use setenv command to boot Android from NFS.
just like this: http://www.codeproject.com/Articles/461037/Booting-Android-completely-over-ethernet

Code:

U-Boot# setenv bootargs 'console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/nfs ip=<client-device-ip> nfsroot=<nfs-server-ip>:<rootfs-path> rootdelay=2'
U-Boot# setenv serverip 'host-pc-ip'
U-Boot# bootm <Load address>

Is it possible ? or I have lost something to do ?

Thank you so much !

 

I don't know which u-boot is using android but every other version I used show progress on serial console and it can be interrupted to check environment variables. And this were official udoo u-boot, curretn master u-boot, u-boot 2015.01, 2015.07, u-boot from solidrun with patches for udoo...

Seems you are doing something very wrong. Make SD card for udoobuntu or openelec and check there.

 

I am not sure is it possible !
I want to create a " Modify-Build-Flash-Test " cycle for Android !
It's mean that I can test Android and quickly recovery to clean status for the next test.
So I tried to use u-boot as bootloader and then set up boot Android from NFS !

Before use UDOO, I have try to use Banana Pi, and compile/write u-boot to sdcard then boot successes, however it has bug with usb keyboard (USB 1.0), or sometimes the Ethernet can't connect my NFS host ! The screenshot as follow:



PS: I have tried many u-boot version (2015-04~2015-07) on this device (Banana Pi), and get the error " ERROR OHCI ....."

Therefore, as I know with use Banana Pi, I can only write the u-boot (compile by myself) and then input the command " setenv" to boot Android from NFS.
That's why I do many instructions as above posts, even it likes stupid work.

Now, I have try to write this image: UDOObuntu 2.0 Minimal Edition for UDOO Quad (from sourceforge: UDOObuntu 2 Minimal Edition for UDOO Quad )
With only write this image, I can boot and input username/password with HDMI.

However, when I connect with serial port, it still no any single.

Maybe it's impossible boot Android from NFS with u-boot on UDOO.

Thanks for your advance help !!

 

I don't know why you don't see anything in serial console. It must always shows something. So fix this first if you want to play with u-boot. Maybe you cable is broken, driver not installed, wrong terminal settings, ...
If you can boot Android from NFS I have no idea. And you know: there is only u-boot bootloader. There is nothing else from what I know.

 

Hello !

I have found the problem that why can't I boot u-boot on UDOO by connect serial port !!!
based on this manual: http://udoo.org/download/files/Documents/UDOO_Starting_Manual_beta0.4_11_28_2013.pdf

3.2.1. i.MX6 Debug Serial Freescale i.MX6 has a dedicated serial port for debugging, which is accessible through an USB-to-RS-232 bridge on micro-USB connector CN6.
The J18jumper switches USB connection coming from CN6 to the iMX6 debug serial port, instead of SAM3X8E programming port. It gives accessto Linux console while



Finally, I can connect UDOO by serial port and see the output log !!!!



Thank you so much for your quickly response !!!! Thank you !!!

 

So I assume you changed the position of this jumper before.

Glad that it's working now.

 

Great!
