Hello, We are using ARM foundation models for evaluation of ARMv8 architecture. We are able to boot the prebuilt images as provided and directed by Linaro on the following link. http://www.linaro.org/engineering/armv8/#tab1
But if we try to recompile the kernel as directed on following link (https://wiki.linaro.org/HowTo/BuildArm64Kernel) we observed that Foundation model is not able to boot the kernel completely. The following is the error message "Starting Boolog daemon: bootlogd: cannot find console device 204:64 under /dev" I screened throughout the linaro site as well as on Google but didn't get any fix suitable for it. I have fixed this bug and would like to submit the patch to linaro upstream branch. Could you please review the patch and let me know how I can upload it to Linaro so that other developers can also use it. PFA the patch for the same. Thanks & BR, Sagar Kadam
From 0612fdc8eeadb192df779b8e32655dd2a707fa93 Mon Sep 17 00:00:00 2001 From: Sagar Kadam <sagar.ka...@open-silicon.com> Date: Tue, 27 Nov 2012 19:17:56 +0530 Subject: [PATCH] [Linaro aarch64 booting Bug] Booting problem on ARM Foundation model:- When pulled a linaro kernel till following git commit 7181edd0539e195f78adedbb6c3878f9f1e0c4bb we observe that the kernel image built for vexpress_defconfig is not able to boot and provide a command prompt at the end. The console hangs after the following boot message: "Starting Boolog daemon: bootlogd: cannot find console device 204:64 under /dev" The reason for this is that CONFIG_DEVTMPFS_MOUNT was not configured into the default config. By enabling this feature, devtmpfs filesystem at /dev, directly after the kernel has mounted the root filesystem. Thus during bootup the /dev/ttyAMA0 device is detected and the command prompt is provided. --- arch/arm64/configs/vexpress_defconfig | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/arch/arm64/configs/vexpress_defconfig b/arch/arm64/configs/vexpress_defconfig index a82cfb8..85ff013 100644 --- a/arch/arm64/configs/vexpress_defconfig +++ b/arch/arm64/configs/vexpress_defconfig @@ -41,6 +41,7 @@ CONFIG_IP_PNP_BOOTP=y # CONFIG_WIRELESS is not set CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug" CONFIG_DEVTMPFS=y +CONFIG_DEVTMPFS_MOUNT=y CONFIG_BLK_DEV=y CONFIG_SCSI=y # CONFIG_SCSI_PROC_FS is not set -- 1.7.6.5
