Hello! I am porting Android on s3c6410 compatible platform. So, using Android sources, i created platform's profile, and compiled ramdisk.img, system.img, userdata.img.
I use 2.6.31-rc4 kernel, in which i included android specific drivers: # Android # CONFIG_ANDROID=y CONFIG_ANDROID_BINDER_IPC=y CONFIG_ANDROID_LOGGER=y CONFIG_ANDROID_RAM_CONSOLE=y CONFIG_ANDROID_RAM_CONSOLE_ENABLE_VERBOSE=y CONFIG_ANDROID_RAM_CONSOLE_EARLY_INIT=y CONFIG_ANDROID_RAM_CONSOLE_EARLY_ADDR=0 CONFIG_ANDROID_RAM_CONSOLE_EARLY_SIZE=0 CONFIG_ANDROID_TIMED_OUTPUT=y # CONFIG_ANDROID_TIMED_GPIO is not set CONFIG_ANDROID_LOW_MEMORY_KILLER=y All my platform's driver compiled into kernel statically. Also i included ramdisk.img into kernel,because it's small sized - 160kb. I just unzipped ramdisk.img wit command gzip -d ramdisk.img and got ramdisk.cpio Here is how i included this ramdisk.cpio to kernel. CONFIG_BLK_DEV_INITRD=y CONFIG_INITRAMFS_SOURCE="/1/ramdisk.cpio" CONFIG_INITRAMFS_ROOT_UID=0 CONFIG_INITRAMFS_ROOT_GID=0 CONFIG_RD_GZIP=y # CONFIG_RD_BZIP2 is not set # CONFIG_RD_LZMA is not set CONFIG_INITRAMFS_COMPRESSION_NONE=y Then I compiled kernel and got uImage. Using U_BOOT i wrote kernle, system.img and userdata.img into nand flash. Here is my parameters in u-boot environment to kernel: mtdparts=s3c6400-nand:384k(u-boot),3m(kernel),65m(system),59m(userdata) console=ttySAC2,115200 which means mtdpart0 - u-boot mtdpart1 - linux kernel mtdpart2 - system.img (yaffs2) mtdpart3 - userdata.img (yaffs2) But it's a pity, at the end of kernel booting i got an error: Freeing init memory: 348K s3c6410_setup_sdhci2_cfg_card: CTRL 2=00000100, 3=80808080 clk_ctrl=0008 s3c6410_setup_sdhci2_cfg_card: CTRL 2=00000100, 3=80808080 clk_ctrl=0008 Kernel panic - not syncing: Attempted to kill init! What can it be the problem with? How init binary from ramdisk.img knows where i placed system.img and userdata.img? Because in the init.rc i found something like this: mount yaffs m...@system /system So isn't it strange? -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
