From: Masahiro Yamada To: linux-arm-kernel@lists.infradead.org, Linux Kernel Mailing List Content-Type: text/plain; charset=UTF-8 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 15159 Lines: 340 Hello experts, I hope this is the correct ML to ask this question. I am struggling to port Linux-4.0-rc7 onto my SoC/board, based on ARM cortex-A9 (single CPU), but the kernel fails to boot with the error: "not syncing: Attempted to kill init! exitcode=0x00000004" I want to use NS16550-compatible UART, Global Timer, and GIC. I wrote a simple device tree source for my own board like this: ------------------>8------------------------------ /dts-v1/; /include/ "skeleton.dtsi" / { compatible = "socionext,ph1-ld4"; memory { device_type = "memory"; reg = <0x80000000 0x20000000>; }; chosen { bootargs = "root=/dev/ram0 console=ttyS0,115200"; }; aliases { serial0 = &uart0; }; cpus { #size-cells = <0>; #address-cells = <1>; cpu@0 { device_type = "cpu"; compatible = "arm,cortex-a9"; reg = <0>; }; }; clocks { #address-cells = <1>; #size-cells = <0>; arm_timer_clk: arm_timer_clk { #clock-cells = <0>; compatible = "fixed-clock"; clock-frequency = <50000000>; }; }; soc: soc { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <1>; interrupt-parent = <&intc>; ranges; uart0: uart@03fb0000 { compatible = "ns16550"; reg = <0x03fb0000 0x100>; clock-frequency = <12288000>; interrupts = <0 81 4>; reg-shift = <1>; fifo-size = <16>; }; intc: interrupt-controller@60001000 { compatible = "arm,cortex-a9-gic"; #interrupt-cells = <3>; #address-cells = <1>; interrupt-controller; reg = <0x60001000 0x1000>, <0x60000100 0x100>; }; global_timer: timer@60000200 { compatible = "arm,cortex-a9-global-timer"; reg = <0x60000200 0x20>; interrupts = <1 11 0x104>; interrupt-parent = <&intc>; clocks = <&arm_timer_clk>; }; }; }; -----------------8<-------------------------------- The Kernel configuration is based on multi_v7_defconfig. The diffconfig against it is like this: (ARCH_UNIPHIER is intended to enable my SoC) ------------------>8------------------------------ CONFIG_ARCH_UNIPHIER=y CONFIG_BLK_DEV_RAM=y CONFIG_BLK_DEV_RAM_SIZE=16384 -----------------8<------------------------------- I passed the kernel image, the device tree, and the initramdisk from U-Boot. I guess I am almost there, but it looks like the kernel failed to run init. The kernel log is as follows: ------------------>8------------------------------ [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 4.0.0-rc7-00032-g8c5ce71-dirty (yamada@beagle) (gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-12ubuntu1) ) #7 SMP Tue Apr 7 12:20:19 JST 2015 [ 0.000000] CPU: ARMv7 Processor [413fc090] revision 0 (ARMv7), cr=10c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] Machine model: socionext,ph1-ld4 [ 0.000000] cma: Reserved 64 MiB at 0x9b000000 [ 0.000000] Memory policy: Data cache writeback [ 0.000000] CPU: All CPU(s) started in SVC mode.
