SDカード作成に失敗して正常にブートしないことが多いので、
作成手順をまとめる。
以下では、/dev/sdcとしてマッピングされた前提で記載する。
Contents
SDカードフォーマット
VMware上のUbuntuに接続すると自動マウントするので、一旦すべて解除
$ sudo umount /dev/sdc1
$ sudo umount /dev/sdc2
fdiskでフォーマットする。
パーティション1：FAT32, 1GB
パーティション2：Linux(ext4), 残り全部

$ sudo fdisk /dev/sdc o # clear the in-memory partition table n # new partition p # primary partition 1 # partition number 1 # default - start at beginning of disk +1G # 1 GB boot partition t # type partition b # VFAT to type of partition number 1 n # new partition p # primary partition 2 # partition number 2 # default - start immediately after preceding partition # default - extend partition to end of disk p # print the in-memory partition table w # write the partition table q # and we're done |
それぞれのパーティションをフォーマット。

$ sudo mkfs.vfat -F 32 -n boot /dev/sdc1 $ sudo mkfs.ext4 -L rootfs /dev/sdc2 |
ファイルコピー
bootデバイス
bootデバイス用のファイルは、[path]/pfm/wksp1/[Application Name]/Hardware/sd_card の下にあるので、これをコピーする。
|
1 |
$ cp [path]/pfm/wksp1/[Application Name]/Hardware/sd_card/* /media/[User]/boot/ |
rootfsデバイス
rootfsデバイス用のファイルは、プラットフォームのものを使用。
[path]/[platform name]/images/linux/rootfs.tar.gz
|
1 |
$ sudo tar xvzf [path]/[platform name]/images/linux/rootfs.tar.gz -C /media/[User]/rootfs/ |
FAQ
rootfsデバイス書き込み失敗
ext4フォーマットをマウントした後、以下のようにkernel panicが発生する場合は、rootfsデバイスの書き込みが失敗している。
手順としては上記で記述してる方法を使ってるだけだが、やり直したら上手く行った。
VM上のUbuntuにローカルPCのUSBメモリを渡してるんだけど、umountがかなり遅く、Ctrl-Cで抜けて強制切断をしたのが悪さをしてた気がする。
