Black screen error trying to virtualize android-linaro with qemu-linaro on the pandaboard ES and on the arm chromebook

by Mario

Hello to everybody. I'm trying to virtualize Linaro-Android 4 with qemu-linaro on two different kind of machines : 1) Pandaboard ES running Ubuntu with this kernel : Linux arm 3.7.2-x6 #1 SMP Sat Jan 12 07:16:37 UTC 2013 armv7l armv7l armv7l GNU/Linux 2) Samsung XE303C12-A01US Chromebook running CHR Ubuntu with this kernel : Linux localhost.localdomain 3.4.0-5-chromebook #5-Ubuntu SMP Fri Feb 8 14:54:53 UTC 2013 armv7l armv7l armv7l GNU/Linux To accomplish the goal I made the experiments with two versions of qemu-linaro : 1) qemu-linaro-1.3.0-2012.12 2) qemu-linaro 1.4 from the GIT rep In both cases I configured qemu-linaro with these parameters : --disable-kvm --disable-tcg-interpreter --enable-curses --enable-sdl --enable-vnc --disable-debug-tcg --enable-vhost-net I tried to follow two different kind of tutorials : 1) http://www.linuxforu.com/2011/06/qemu-for-embedded-systems-development-part… 2) https://wiki.linaro.org/KenWerner/Sandbox/AndroidQEMU?highlight=%28QEMU%29|…<https://wiki.linaro.org/KenWerner/Sandbox/AndroidQEMU?highlight=%28QEMU%29%…> On the TUTORIAL n. 1: 1) Created a small test program, test.c, with the basic “Hello world”: #include<stdio.h> int main(){ printf("Welcome to Open World\n"); } # gcc test.c -o test 2) Built the Linux kernel for ARM # tar -jxvf linux-2.6.37.tar.bz2 (but I tried with a lot of other kernel versions) # cd linux-2.6.37 # make menuconfig ARCH=arm # make ARCH=arm uImage -s # qemu-system-arm -M versatilepb -m 128M -kernel /home/user/Desktop/linux-2.6.37/arch/arm/boot/uImage RESULT = black screen inside the qemu-linaro window without error messages 3) Developed a dummy filesystem (hello.c) for testing #include<stdio.h> int main(){ while(1){ printf("Hello Open World\n"); getchar(); } } # gcc hello.c -static -o hello 4) Created a root filesystem # echo hello | cpio -o --format=newc > rootfs 5) Testing : qemu-system-arm -M versatilepb -m 128M -kernel /home/user/Desktop/ linux-2.6.37/arch/arm/boot/uImage -initrd rootfs -append "root=/dev/ram rdinit=/hello" RESULT = black screen inside the qemu-linaro window without error messages On the TUTORIAL n. 2 : 1) Patched : qemu-linaro-1.3.0-2012.12 with : sed -i "s/#define INITRD_LOAD_ADDR 0x00d00000/#define INITRD_LOAD_ADDR 0x01d00000/" qemu-linaro-1.3.0-2012.12/hw/arm_boot.c and also qemu-linaro 1.4 from the GIT rep with the same patch: sed -i "s/#define INITRD_LOAD_ADDR 0x00d00000/#define INITRD_LOAD_ADDR 0x01d00000/" qemu-linaro/hw/arm_boot.c 2) wget http://releases.linaro.org/12.05/android/images/vexpress-ics-gcc47-armlt-tr… gunzip vexpress-ics-gcc47-armlt-tracking-open.img.gz sudo kpartx -a vexpress-ics-gcc47-armlt-tracking-open.img sudo mount /dev/mapper/loop0p1 /mnt -o loop,ro cp /mnt/uImage /mnt/uInitrd . sudo umount /mnt sudo kpartx -d /dev/mapper/loop0p* dd if=uImage of=vmlinuz skip=64 bs=1 dd if=uInitrd of=initrd.gz skip=64 bs=1 3) Tried to boot Linaro Android 12.05 using qemu-linaro-1.3.0-2012.12 and also qemu-linaro 1.4 from the GIT rep on the Pandaboard ES with this : qemu-system-arm -M vexpress-a9 -m 1024 -smp 1 -snapshot -serial stdio -no-reboot -kernel vmlinuz -initrd initrd.gz -drive file=vexpress-ics-gcc47-armlt-tracking-open.img,if=sd,cache=writeback --append "console=tty0 console=ttyAMA0,38400n8 rootwait ro init=/init androidboot.console=ttyAMA0" and on the Samsung XE303C12-A01US Chromebook with this : qemu-system-arm -M vexpress-a15 -cpu-cortex-a15 -m 1024 -smp 1 -snapshot -serial stdio -no-reboot -kernel vmlinuz -initrd initrd.gz -drive file=vexpress-ics-gcc47-armlt-tracking-open.img,if=sd,cache=writeback --append "console=tty0 console=ttyAMA0,38400n8 rootwait ro init=/init androidboot.console=ttyAMA0" I've also tried wth : qemu-system-arm -M vexpress-a15 -cpu cortex-a15 -m 1024 -smp 1 -snapshot -serial stdio -no-reboot -kernel uImage -initrd uInitrd -drive file=vexpress-ics-gcc47-armlt-tracking-open.img,if=sd,cache=writeback --append "console=tty0 console=ttyAMA0,38400n8 rootwait ro init=/init androidboot.console=ttyAMA0" Also tried with different kind of combinations,like : -M versatilepb ; -M vexpress-a9 ; -cpu cortex-a9 ; -m 512 ; but the RESULT is still the smae = black screen inside the qemu-linaro window without error messages. Any help ? Instead,debian_lenny_armel_desktop is virtualized very well with qemu-linaro following this procedure : a) wget vmlinuz-2.6.32-5-versatile,initrd.img-2.6.32-5-versatile and debian_lenny_armel_desktop from here : http://people.debian.org/~aurel32/qemu/armel/ b) tried to virtualize debian_lenny_armel_desktop with : qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda debian_lenny_armel_desktop.qcow2 -append "root=/dev/sda1" and it works.... -- Mario.

Need magic repo => repo.git rewrite for http://git.linaro.org/git-ro/

by Paul Sokolovsky

Hello, On http://android.git.linaro.org/git-ro/, we have Apache configuration for automatically rewriting URLs from .../<base>/... form to .../<base>.git/... form (to match underlying FS layout). However, it doesn't seem to be set up for http://android.git.linaro.org/git-ro/ , which leads to failed checkouts for Android, following is the symptom: error: Fetch failed. fatal: http://git.linaro.org/git-ro/people/tomgall/libjpeg-turbo/libjpeg-turbo/inf… not found: did you run git update-server-info on the server? Fetching projects: 44% (151/341) fatal: http://git.linaro.org/git-ro/tools/pm-qa/info/refs not found: did you run git update-server-info on the server? Can you please setup the URL rewriting to fix that? -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Did anyone change access permissions on android.git.linaro.org?

by Bernhard Rosenkränzer

New problem: $ git clone git://android.git.linaro.org/people/pfefferz/at.git Cloning into 'at'... fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. OTOH the repository does exist, $ git clone ssh://bero@android.git.linaro.org:29418/people/pfefferz/at.git works just fine. Did someone tighten permissions on people/ so only the owner can check it out over git:// or something? ttyl bero

Re: 13.01 Versatile Express Android build unstable

I've just tested out the 13.01 release notes again by following them to recreate and replacing my TC2's firmware and configure UEFI; and that works for me to boot a fresh 13.01 Android image from an SD card. If you aren't having any success with that configuration, then further things I can suggest are: 1) To make sure any firmware changes have really taken hold, try erasing all the NOR flash. You can do this from the bootloader Cmd> prompt by entering "flash" to get a Flash> prompt, then enter 'eraseall'. After the flash has finished erasing, reboot the board and the firmware will be reprogrammed again. 2) In case there is an error in the UEFI config (I know it's a bit fiddly to enter) then you could try the Linaro firmware zip we have for the forthcoming 13.02 release [1]. This has a UEFI version which ignores the SD card UUID and so doesn't need reconfiguring every time you create a new disk image. It also has the benefit that the default boot config will work without you needing to manually set anything. If you try this latest UEFI, I suggest you also erase the flash as above, to make extra sure there is no old config left over from a previous version.

Auto boot / power-0n / switch-on

by Mahmoud Ebeid

Dear sir, I saw that some devices when I insert the charger inside the plug of the tablet they switch automatically on (such as Ipad or Iphone). The tablet that I bought does not support this function but if I insert the charger, the animation of the battery automatically starts so I believe that the CPU could start the OS. After some research I figured out that I must modify the Boot Image and so I need to bake a custom rom able to boot the OS when I insert the charger into the plug. Can anyone help me? it's really important, I am been working on this in the last two months with zero results. PLEASE HELP THANK YOU Br, Mahmoud Ebeid Tel+ 201007780097 , +971509501644
