Hi, I've followed several tutorials ans wiki's on how to compile my own kernel for the mini2440. For now the main reason for doing this is to try and change the boot logo which I have not been able to change. I followed mostly the following tutorials: 1.) http://code.google.com/p/friendlyarm/wiki/Linux_Tutorial 2.) http://wiki.linuxmce.org/index.php/Mini2440 3.) http://bill.station51.net/index.php?post/2010/07/14/HOWTO%3A-Cross-Compi... 4.) http://www.electronics.diycinema.co.uk/embedded/mini2440/2009/09/ 5.) http://bill.station51.net/index.php?post/2010/05/08/HOWTO%3A-Setting-up-... Firstly I have a few questions about parameters which I do not understand or ones who gives me errors: 1.) In link 1.) they compile the kernel with the "-j4" setting(make ARCH=arm O=../../kernel-bin/ -j4). What is this setting for? Does it specify the number of parallel processes allowed or is it something completely different? I'm compiling from a virtual machine with only one CPU, do I set this yo -j1? 2.) From link 1.) I specify the architecture using "CC='arm-none-linux-gnueabi-gcc -march=armv4t -mtune=arm920t". What does this command do? Secondly I would like to decsribe my compilation procedure that does not want to display the new logo: 1.) Install the arm toolchain described in link 5.) 2.) mkdir ~/kernel 3.) cd ~/kernel 4.) git clone git://repo.or.cz/linux-2.6/mini2440.git 5.) cd mini2440 6.) mkdir -p ../kernel-bin 7.) pngtopnm logo.png | pnmtoplainpnm > logo_linux_clut224.ppm OR pngtopnm logo.png | ppmquant -fs 223 | pnmtoplainpnm > logo_linux_clut224.ppm 8.) cp logo_linux_clut224.ppm ~/kernel/mini2440/drivers/video/logo 9.) export CROSS_COMPILE=arm-none-linux-gnueabi- 10.)CC='arm-none-linux-gnueabi-gcc -march=armv4t -mtune=arm920t' 11.)export CC 12.)make ARCH=arm O=../kernel-bin/ distclean 13.)make ARCH=arm O=../kernel-bin/ mrproper 14.)make ARCH=arm O=../kernel-bin/ mini2440_defconfig 15.)make ARCH=arm O=../kernel-bin/ menuconfig 16.)I "Load an alternative configuration file", config_mini2440_t35, because I have a T35 lcd. 17.)Add support for wanted file systems and MTD (I only add ext3 since my rootfs is on ext3 filesystem on the SD) 18.)I 'Save an alternative configuration file" as .config then Exit 19.)make ARCH=arm O=../kernel-bin/ -j4 20.)make ARCH=arm O=../kernel-bin/ -j4 modules 21.)make ARCH=arm O=../kernel-bin/ INSTALL_MOD_PATH=.. modules_install 22.)../../uboot/mini2440/tools/mkimage -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008000 -d ../kernel-bin/arch/arm/boot/zImage ../ksudoernel-bin/arch/arm/boot/uImage 22.)sudo cp ../lib/modules/2.6.32-rc8/ /media/rootfs/lib/modules/ -r 22.)sudo cp ../kernel-bin/arch/arm/boot/uImage /media/boot -r 23.)sync 24.)umount /media/* With this my logo still does not boot and I get a kernel panic when using uboot or "load Image of Linux...
