BB-View 7 on BBB with Debian or Ubutun or Buildroot

Well I tried to compile the bb-black-kernel-3.8.13-bb-view.tar.gz2 Angstrom Kernell source code downloaded on element14 with arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.8-2013.10 - Linaro GCC 2013.10)

like describe here:

http://eewiki.net/display/linuxonarm/BeagleBone

I did in kernel source directory this commands:

make ARCH=arm menuconfig

make ARCH=arm CROSS_COMPILE=/home/ana/Téléchargements/BBB/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf- uImage modules

and I've got this error:.

[/CODE]

Your Kernel Compression mode is set to LZO but you don't have the proper tools installed

In menuconfig, go to General Setup and change it back to Gzip:

Alternatively, the lzop source is available here http://www.lzop.org/

Thank you very much for your  answer^^  I'll be able to continue my compilation

Well, I finished with success the compilation,

after I did this:

(I used the ubuntu img from armhf)

[CODE]

# xz -cd ubuntu-precise-12.04.3-armhf-3.8.13-bone30.img.xz > /dev/sdb

# cd /media/rootfs_armhf.com/

# cp /home/ana/Téléchargements/BBB/kernel/kernel/arch/arm/boot/uImage boot/

# make -C /home/ana/Téléchargements/BBB/kernel/kernel/ INSTALL_MOD_PATH=`pwd` ARCH=arm CROSS_COMPILE=/home/ana/Téléchargements/BBB/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf- modules_install

#cd boot/

#mv vmlinux-3.8.13-bone30 vmlinux-3.8.13-bone30origine

#mv uImage vmlinux-3.8.13-bone30

#chmod a+x  vmlinux-3.8.13-bone30

[/CODE]

and I changed optargs=fixrtc line in uEnv.txt in  /media/BOOT_ARMHF/

like this:

[CODE]

mmcpart=2

optargs=dispmode=7inch_LCD

uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if mmc rescan; then kd=1; fi; mmc dev 1; fi; setenv mmcroot /dev/mmcblk${kd}p${mmcpart} ro

loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}

loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}

[/CODE]

But when I put the SDcard in the BBB it doesn't boot even if I push the uSD button at power up...

If someone has a clue..

EDIT: I understand where is my msitake.. I have to compile Uboot also like described here:

http://www.farnell.com/datasheets/1780810.pdf

but now I'm looking for where I could find this files:

linux-3.2.0-psp04.06.00.11-bb-view.tar.bz2

and

u-boot-2013.01.01-psp06.00.00.00-bb-view.tar.bz2

and do this following instructions:

Compiling "uboot" from element14

1)

Execute the following commands to uncompress the uboot source code

$ cd $HOME

$ tar xvf u-boot-2013.01.01-psp06.00.00.00-bb-view.tar.bz2

2)

Execute the following instructions to compile

$ cd $HOME/u-boot-2013.01.01-psp06.00.00.00

$ make CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm distclean

$ rm -rf am335x

$ make O=am335x CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm am335x_evm

After the compilation is done, the files “MLO” and “u-boot.img” can be found under “am335x/” of the current directory.

Compiling the "Kernel" from element14

Execute the following instructions to unzip the source code and compile the kernel image;

$ cd $HOME

$ tar xvf linux-3.2.0-psp04.06.00.11-bb-view.tar.bz2

$ cd linux-3.2.0-psp04.06.00.11

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_evm_defconfig

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage modules

A kernel file named “uImage” with LCD module support is generated under “arch/arm/boot/”.

System Update with BB-View Support

1)Format a flash drive or a TF card to FAT32 and mount

it under the Ubuntu Linux system, and then execute the following instructions

to copy the image to the flash drive or TF card. (These instructions assume the flashdrive or TF card is mounted under “/mnt”)

$ cd $HOME

$ cp u-boot-2013.01.01-psp06.00.00.00/am335x/MLO /mnt

$ cp u-boot-2013.01.01-psp06.00.00.00/am335x/u-boot.img /mnt 

$ cp linux-3.2.0-psp04.06.00.11/arch/arm/uImage /mnt 

$ mkdir /mnt/rootfs 

$ cd $HOME/linux-3.2.0-psp04.06.00.11

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install INSTALL_MOD_PATH=/mnt/rootfs

$ cd /mnt/rootfs

$ tar -czvf ../kernel_modules.tar.gz ./

$ cd /mnt

$ rm –rf rootfs 

2)

Connect BB-View to the BeagleBone or BeagleBone Black  and then connect the power supply; Insert the flash drive or TF card into the

BeagleBone or BeagleBone Black and execute the following instructions in PuTTY

to update the system image (If a TF card is used instead of a flash drive, please change the path in the instructions accordingly)

$ cp /media/sda1/MLO /media/mmcblk0p1/

$ cp /media/sda1/u-boot.img /media/mmcblk0p1/

$ cp /media/sda1/uImage /media/mmcblk0p1/

$ tar -xvf /media/sda1/kernel_modules.tar.gz -C /

Do you think It would be ok to make boot Ubuntu with BB-View if I follow that step.

The SD needs a minimum of two partitions,  normally /dev/mmcblk0p1 & /dev/mmkblk0p2

p1 needs to be formatted as fat and at minimum needs two files MLO and u-boot.img the boot code in the SoC will look for MLO on the first partition, load it and run it.  In normal circumstances, MLO is actually u-boot-spl which will just do some basic hardware setup and then load u-boot.img. What happend from there is down to whatever bootscript was compiled into u-boot.

Some versions of u-boot try to load uImage, other newer versions have been updated to load zImage directly. If your u-boot is trying lo load a zImage but you've built a uImage then it's not going to work.

Your best way forward is to attach a serial console, you'll see messages from the boot process there which should help you debug the problem.

Thanks for your answer.

I don't have a serial cable with me here but it's what I plan to use^^

I edited my previous message and as you see, I guess that I have to compile also U-boot to use BB-view because I have well MLO and u-boot.img file in my BOOT partition..

Hi again,

Well I progress well  ^^

I recompiled the kernell like this to have a zImage file(with gzip compression):

make ARCH=arm CROSS_COMPILE=/home/ana/Téléchargements/BBB/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf- zImage modules

After I did all the same steps describes above with the zImage instead of the uImage.

Then I took the am335x-boneblack-lcd7.dtb file in the angstrom-image.zip and I copied it in the /media/rootfs_armhf.com/boot/dtbs  directory with am335x-boneblack.dtb name .

And it works, it boot well, and I see the shell on the BB-View ^^

Now I think I will install a desktop or maybe just openBox. I'll need to calibrate the touch screen anyway.. I know that there is a pointercal file in the TI and Angstrom Image but I don't know what sofware I should use... any idea? ^^

for calibration I used ts_calibrate outside of gnome

I try to recompile the kernel from element14 also because I want to change the BB-VIEW-LCD4-01-00A0.dtbo file but I'm very new to Linux, can you please tell me the steps you did to accomplish this. Thank you!

Hello,

Well I did exactly what I wrote before :

I download the source file here:

http://downloads.element14.com/downloads/bb-view/angstrom/angstrom-source.zip?COM=BeagleBoneBlack

and others files here:

http://downloads.element14.com/downloads/bb-view/angstrom/angstrom-image.zip?COM=BeagleBoneBlack

Then I change directory in kernell source directory and I run this commands:

make ARCH=arm menuconfig

(I choosed gzip compression)

make ARCH=arm CROSS_COMPILE=/home/ana/Téléchargements/BBB/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf- zImage modules

(because the bootloader wants a zImage)

after I took the am335x-boneblack-lcd7.dtb file in the angstrom-image.zip and I copied it in the rootfs_armhf.com/boot/dtbs  directory of my ubuntu armhf file system with am335x-boneblack.dtb name.

Also in the Boot partition, I changed uEnv.txt to use LCD 7" :

mmcpart=2

optargs=dispmode=7inch_LCD

uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if mmc rescan; then kd=1; fi; mmc dev 1; fi; setenv mmcroot /dev/mmcblk${kd}p${mmcpart} ro

loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}

loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}

For the calibration I did:

apt-get update

apt-get install lxde lxde-core lxde-icon-theme

apt-get install xinput-calibrator

in LXDE, I launched xinput-calibrator like this:

cd /usr/share/bin

./xinput-calibrator --output-type xinput

And then add calibration option settings obtained to the touchscreen InputClass section in 10-evdev.conf after driver "evdev":

Option "Calibration" "96 3914 155 3899"

(sudo  nano /usr/share/X11/xorg.conf.d/10-evdev.conf)

Now   I have an issue with virtual keybord onboard which is all black ! Maybe I'll try to fix it or I'll try the florence virtual keyboard ..

Good to see you have it working.  Getting a serial cable is well worth it, it'll make solving this sort of thing in the future much easier.

Can't help you with the touch screen, I don't have one myself so have never investigated how to set them up on the BBB.
