Problem booting using latest linaro-linux-tracking (3.16.0-rc5)/mainline kernel (3.16.0-rc4) on Samsung Arndale Baord

by Mohammad Merajul Islam Molla

Hello, I am having problem booting from latest linaro-linux-tracking (3.16.0-rc5) on Samsung Arndale Board (with two cpus). The same thing happens with mainline kernel (3.16.0-rc4). Here is what happens - 1. During build I got the error message - LD sound/built-in.o MK_FW firmware/edid-1920x1080.fw.gen.S make[1]: *** No rule to make target `firmware/edid-1920x1080.fw', needed by `firmware/edid-1920x1080.fw.gen.o'. Stop. make: *** [firmware] Error 2 I set CONFIG_EXTRA_FIRMWARE="" and could proceed with build. 2. At the end of build I got the below error message - Kernel: arch/arm/boot/zImage is ready multiple (or no) load addresses: This is incompatible with uImages Specify LOADADDR on the commandline to build an uImage make[1]: *** [arch/arm/boot/uImage] Error 1 make: *** [uImage] Error 2 I passed loadaddr as parameter - make uImage LOADADDR=0x40008000 (this address I got from build output of linux-linaro-tracking 3.14.0). With this build was successful and uImage generated. 3. After that I got the following log during boot - [ 1.125626] Trying to unpack rootfs image as initramfs...
