Hi Ankur, i am new with Yocto can you explain in a little bit more detailed?
I commented in blue what i dindt understand. Can you tell me before doing bitbake waht did you do? Are you able to use USB/HDMI/SOUND on Chipsee Display? I have the Capacitive Touch what sould i do different? It runs on I2C. Thank you, Michael ///////////////////////////////////////////////////////////////////////////////////////////////////// Well for time being i downloaded the Yocto_daisy(1.6) toolchain and installed it in my PC. And compiled the Linux external to Yocto build. Here are steps. I followed below steps in my virtualbox installed ubuntu. 1. in Yocto_daisy build core-image-sato, using following command, 2. bitbake core-image-sato This is the first thing you do? 3. Prepare micro SD card with rootfile system, SPL & U-Boot, uImage, dtb, uEnv.txt. How do you prepare the SD card? 4. Clone beaglebone black Linux using following command git clone --depth=1 https://github.com/beagleboard/linux 5. Download yocto-1.6(daisy) toolchain from following link. http://downloads.yoctoproject.org/releases/yocto/yocto-1.6/toolchain/ Based on your machine type download from either i686 or x86_64 I downloaded following toochain. http://downloads.yoctoproject.org/releases/yocto/yocto-1.6/toolchain/i686/poky-eglibc-i686-core-image-sato-armv7a-vfp-neon-toolchain-1.6.sh 6. Install toolchain by running download toolchain script. By default it installs into opt directory, I installed it in default path. 7. In terminal traverse to the above downloaded Linux directory. and set toolchain environment by running following command, source /opt/poky/1.6/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi 8. Now configure kernel using following command, make bb.org_defconfig 1. and then build kernel using following command make uImage LOADADDR=0x80008000 -j4 2. now we shall install the modules into local directory using following commands, mkdir bbb_modules export INSTALL_MOD_PATH=/home/ankur/linux/bbb_modules/ make modules_install 3. when kernel is built copy uImage(from /arch/arm/boot) and am335x-boneblack-bbb-exp-c.dtb(from /arch/arm/boot) to the BOOT partition of the micro SD card. For FYI my uEnv.txt looks like this Disable: HDMI bootargs=console=ttyO1,115200n8 root=/dev/mmcblk0p2 rootfstype=ext4 rw rootwait; bootcmd=mmc rescan ; mmc dev 0 ; fatload mmc 0 0x80007fc0 uImage ; fatload mmc 0 0x80F80000 am335x-boneblack-bbb-exp-c.dtb ; echo Ankur... ${bootcmd}; bootm 0x80007fc0 - 0x80F80000; uenvcmd=boot; 11 . Now copy modules from local directory to the micro SD card, using following commands, cp -a /home/ankur/linux/bbb_modules/lib /media/ankur/ROOT/ sync 12. Eject the card put it into Beaglbone Black and power on the BBB+LCD. I am yet to get the Touch calibration working for LCD but once I find it i will update the answer. Another pending thing is build above kernel into Yocto build system. I will update the answer once i am done with that. Hope this helps someone with the same issue. > > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
