Hi, I have built an unmodified kernel for the Nexus S but when I run it I see the following error in my logcat output:
ERROR/FramebufferNativeWindow(190): couldn't open framebuffer HAL (No such device) - so although I can still adb shell onto the handset my boot has failed at this point. I am building an unmodified kernel as follows: git clone git://android.git.kernel.org/kernel/samsung.git cd samsung make ARCH=arm CROSS_COMPILE=~/mydroid/prebuilt/linux-x86/toolchain/arm- eabi-4.4.3/bin/arm-eabi- herring_defconfig make ARCH=arm CROSS_COMPILE=~/mydroid/prebuilt/linux-x86/toolchain/arm- eabi-4.4.3/bin/arm-eabi- ~/mydroid/out/host/linux-x86/bin/mkbootimg --cmdline 'console=ttyFIQ0 no_console_suspend' --base 0x30000000 --pagesize 4096 --kernel zImage --ramdisk mtd2.img-ramdisk.gz -o boot.img where - mtd2.img-ramdisk.gz was extracted from the mtd2 image from my Nexus S using split_bootimg.pl. ~/mydroid contains my gingerbread build my build environment is Ubuntu 10.10 64bit in a VM Can anyone suggest what I'm doing wrong? Thanks very much. ---------------------------------------------------------------------------------------------------------------------------------------------------- Here's the pertinent part of my boot log 03-16 09:58:04.113: INFO/Zygote(188): ...preloaded 1830 classes in 2016ms. 03-16 09:58:04.113: ERROR/Zygote(188): setreuid() failed. errno: 17 03-16 09:58:04.128: DEBUG/dalvikvm(188): GC_EXPLICIT freed 18K, 52% free 2460K/5123K, external 0K/0K, paused 17ms 03-16 09:58:04.132: INFO/Zygote(188): Preloading resources... 03-16 09:58:04.148: DEBUG/dalvikvm(188): GC_EXTERNAL_ALLOC freed <1K, 52% free 2462K/5123K, external 0K/0K, paused 17ms : 03-16 09:58:04.386: DEBUG/dalvikvm(188): GC_EXPLICIT freed 1K, 51% free 2526K/5123K, external 1625K/2137K, paused 17ms 03-16 09:58:04.390: INFO/dalvikvm(188): System server process 190 has been created 03-16 09:58:04.390: INFO/Zygote(188): Accepting command socket connections 03-16 09:58:04.449: INFO/sysproc(190): Entered system_init() 03-16 09:58:04.449: INFO/sysproc(190): ServiceManager: 0x128df8 03-16 09:58:04.449: INFO/SurfaceFlinger(190): SurfaceFlinger is starting 03-16 09:58:04.449: INFO/SurfaceFlinger(190): SurfaceFlinger's main thread ready to run.
