Francis Kumar

Other Parts Discussed in Thread: AM1808, OMAP-L138

Hi,

I am using Texas AM1808 Target. Before i have worked in Qt application and linux drivers.

I am new to android. I want to port the android image on to the AM1808. I wish to download android froyo source.

Can i know the steps, how to install the SDK and which version of Android tree is required to port

on to the target.

Hi Francis,

We no longer support Android for AM1808, there is a much better low cost processor for Android available now see http://www.ti.com/am335x

If you still want to go for Android on AM1808, then please use below link as starting point.

Every thing is captured in the wiki link I posted before. Please follow the wiki link.

http://processors.wiki.ti.com/index.php/TI-AM1808-Android-FroYo-DevKit_UserGuide#Downloading_the_AM1808EVM_Android_Froyo.28Rowboat.29_sources

As I mentioned, we no longer support Android on AM1808 as we have better low cost processors now.

Hi,

Almost our design is over with Qt application. we are going start our production using AM1808.

Next Our aim is to port the Android image on to the same target AM1808. This time we are not changing our processor.

Above link is not clear. giving error below:

root@ubuntu:/home/kumar/ANDROID_ROOT# sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev minicom tftpd uboot-mkimage

H Francis,

The Sun JDK is no longer in Ubuntu's main package repository. In order to download it, you need to add the appropriate repository

Java 5: for Froyo and older

$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy main multiverse"
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy-updates main multiverse"
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk

Hi,

When i use the command I get the following error message:

root@ubuntu:/home/kumar/ANDROID_ROOT/am1808/TI-Android-Froyo# repo init -u git://gitorious.org/rowboat/manifest.git -m rowboat-froyo-am1808.xml

	/home/kumar/ANDROID_ROOT/bin/repo: line 1: `<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">'

I tried in different way :

/home/kumar/ANDROID_ROOT/bin/repo: line 1: syntax error near unexpected token `newline'
/home/kumar/ANDROID_ROOT/bin/repo: line 1: `<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">'


Could you please help me.

TI__Expert 7220 points

Hi Francis,

Hope you have ubuntu as the host machine. Ubuntu version 10.04 or later need to be installed.
Also make sure you have installed latest version of python on your host. This is required for the repo tool to work.

0 Arun Joseph over 13 years ago in reply to Arun Joseph

TI__Expert 7220 points

Hi Francis,

One more thing, the tool repo may not have downloaded to your host if you have tried the step behind a http proxy.

curl http://android.git.kernel.org/repo > ~/bin/repo 

Please set "export http_proxy=<proxy url>:<port> before "curl" step.

0 Francis Kumar over 13 years ago in reply to Arun Joseph

Expert 1330 points

Hi,

We have all admin access is available. We don't have any Proxy servers here.

Still same error is giving in the repo script.

/home/kumar/ANDROID_ROOT/bin/repo: line 1: syntax error near unexpected token `newline'
/home/kumar/ANDROID_ROOT/bin/repo: line 1: `<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">'

Please suggest some more.

Regards,

Francis

0 Arun Joseph over 13 years ago in reply to Francis Kumar

TI__Expert 7220 points

Hi Francis,

This clearly indicate that repo tool did not get downloaded.

Try this latest link for repo

curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

Francis,

Which is the command hanging?

Normally the command

$ repo init -u git://gitorious.org/rowboat/manifest.git -m rowboat-froyo-am1808.xml

finishes quickly.

And the command

$ repo sync

will take more than 24 hour to clone the complete repositories.

Hi Arun,

Almost I got the android source and created file system. This android file system is booting from SDCard.

While mounting the file system gives an error. I followed these steps in my target

Kernel Image is loaded in SD-Card (FAT32)
Android file system is loaded in SD-Card (rootfs) = I got this file system based on the following commands
1. Run repo sync
2. Edited in the Makefile

make TARGET_PRODUCT=AM1808evm TARGET_BUILD_VARIANT=tests -j8 droid
I copied tar file in to SD-Card. tar jxfv android_rootfs.tar
Then I booted the AM1808 target with SD-Card with the help of bootarg command: setenv bootargs 'console=ttyS2,115200n8 noinitrd root=/dev/mmcblk0p2 rw init=/init rootdelay=5 mem=32M mpurate=450 androidboot.console=ttyS2'
$ cd out/target/product/am1808evm
$ mkdir android_rootfs
$ cp -r root/* android_rootfs
$ cp -r system android_rootfs
sudo ../../../../build/tools/mktarball.sh ../../../host/linux-x86/bin/fs_get_stats android_rootfs . rootfs rootfs.tar.bz2
I copied tar file in to SD-Card. tar jxfv android_rootfs.tar
Then I booted the AM1808 target with SD-Card with the help of bootarg command: setenv bootargs 'console=ttyS2,115200n8 noinitrd root=/dev/mmcblk0p2 rw init=/init rootdelay=5 mem=32M mpurate=450 androidboot.console=ttyS2'

Once booting from kernel to File system. Given blow error.

Hi Karthika,

Can you send your bootargs with logcat.

Regards,

Hi Francis,

it seems that you've been more successful porting Android to the OMAP-L138 than we were on as described in this thread:

http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/p/119623/870448.aspx#870448

How did you overcome the issue that booting stops after this message?

Starting kernel ...

Uncompressing Linux............................................................................................................................................... done, booting the kernel.

With best regards

Hi Christian,

It can be easily rectifying your issue. But I would like to know the below queries how the default settings are specified in your OMAP-L138 board.

How did you booting your kernel i.e Ram Disk or NFS/TFTP or SD-Card ??
What is your file system it is Qt or Android???
What is your JTAG ID it is mentioned in this path: I want your file in your Linux kernel path: /linux source/arc/arm/mach-davinci/da850.c ??
What is your ‘bootargs’ before kernel compressing??.
Are you running this process in EVM or your own custom design based on LogicPD???

Thanks,

Francis

Hi Francis,

1.) I try to boot the kernel from the SD-card. I copied 'uImage' to the first partition from 'arch/arm/boot/uImage' by 'sudo cp -r uImage /mnt/fat32 (this is /dev/sdb1 in my case). U-boot is flased to SPI flash.

2.) The file system is Android built by following the instructions from http://processors.wiki.ti.com/index.php/TI-AM1808-Android-FroYo-DevKit_UserGuide .

3.) I'm sorry I coundn't find /linux source/arc/arm/mach-davinci/da850.c - no idea where to start looking for this on my computer. I guess that is the point - the processor checksum is probably wrong. I use the OMAP-L138 on Logic PD's Zoom OMAP-L138 Experimenter board, not the EVM.

4.) The bootargs are taken from the manual above as well:

U-boot> setenv bootargs 'init=/init console ttyS2,115200n8 ip=off rw root=/dev/mmcblk0p2 rootfstype=ext3 rootwait mem=128M mpurate=450 androidboot.console=ttyS2'

the line

U-boot> setenv bootargs 'sf probe 0; sf read C0700000 C0000 300000; bootm c0700000'

has been omitted since I didn't flash the kernel to the SPI flash memory but copied it to the first partition of the SD-card. It is loaded and uncompressed from here.

5.) As mentioned above the used hardware is Logic PD's Zoom OMAP-L138 Experimenter board.

Thank you very much for your help!

With best regards

Christian

Hi Chritian

What is the size of DDR 64M/128M of your OMAP-L138??.

The above bootargs are correct..Please try with below bootargs again

setenv bootargs 'init=/init console=ttyS2,115200n8 ip=off rw root=/dev/mmcblk0p2 rootwait nolock mem=64M mpurate=450 androidboot.console=ttyS2'

setenv bootcmd 'sf probe 0; sf read C0700000 C0000 300000; bootm c0700000'

boot

Please go through your linux tree under /linux source/arc/arm/mach-davinci/da850.c edit this file and add in your kernel and rebuild it.

/linux source/arc/arm/mach-davinci/da850.c

In this file please check your JTAG ID should as below:

/* Contents of JTAG ID register used to identify exact cpu type */
static struct davinci_id da850_ids[] = {
{
.variant = 0x0,
.part_no = 0xb7d1,
.manufacturer = 0x017, /* 0x02f >> 1 */
.cpu_id = DAVINCI_CPU_ID_DA850,
.name = "da850/omap-l138",
},
{
.variant = 0x1,
.part_no = 0xb7d1,
.manufacturer = 0x017, /* 0x02f >> 1 */
.cpu_id = DAVINCI_CPU_ID_DA850,
.name = "da850/omap-l138/am18xx",
},
};

Another try, you have any RTC on your board, Please include your RTC in menu-config and build and try it.

And remove RTC in menu-config and try it.

Look frward to see your positive response.

Thanks,

Francis

Hi Kumar,

your suggestions were leding to success - thank you!

Now the details:

- The DDR RAM size on my SOM is 128MByte so the bootargs are correct.

- The file 'da850.c' does the 'kernel hacking' to forward the right processor type. I added the second variant - this was lacking before.

This file was located in '/rowboat-android/kernel/arch/arm/mach-davinci' so I had to look for it ;-). This is the main issue.

After rebuilding the kernel it started the fs and the android logo, GUI and nice apps. Next I'll go to use the network.

I will forward the link to this thead to all other threads where is issue is unsolved yet.

Thanks again for making me happily running android on the OMAP-L138 eXperimenter!

With best regards

Christian
