Raspberry Pi 5 に NetBSD をインストールし直したので、その手順を記録し ておくでござる。
まず、 Raspberry Pi 5 用の UEFI firmware をダウンロードするでござる。

今日、久しぶりに UEFI firmware をダウンロードしようとして気づいたので ござるが、 https://github.com/worproject/rpi5-uefi はもうメンテナンスされていないようでござる。何か代わりになるものはある のでござろうか。

micro-SD カードは sd0 として見えているようなので、この sd0 を FAT32 で フォーマットするでござる。まず、全てを消去するでござる。

FAT32 のパーティションを作成するでござる。

確認してみるでござる。

disklabel を使ってパーティションを確認するでござる。

newfs_msdos を使って FAT32 でフォーマットするでござる。
# newfs_msdos -F 32 /dev/rsd0e /dev/rsd0e: 62303424 sectors in 1946982 FAT32 clusters (16384 bytes/cluster) MBR type: 11 bps=512 spc=32 res=32 nft=2 mid=0xf0 spt=32 hds=64 hid=0 bsec=62333889 bspf=15211 rdcl=2 infs=1 bkbs=2
mount してみるでござる。
# mount -t msdos /dev/sd0e /mnt # df -m /mnt Filesystem 1M-blocks Used Avail %Cap Mounted on /dev/sd0e 30421 0 30421 0% /mnt
FAT32 でフォーマットした micro-SD カードを mount できたので、そこに RPi5_UEFI_Release_v0.3.zip の中身を書き込むでござる。
# cd /mnt # unzip /tmp/rpi5/RPi5_UEFI_Release_v0.3.zip Archive: /tmp/rpi5/RPi5_UEFI_Release_v0.3.zip extracting: config.txt extracting: bcm2712-rpi-5-b.dtb extracting: RPI_EFI.fd # ls -lF total 2080 -rwxr-xr-x 1 root wheel 2031616 Mar 16 2024 RPI_EFI.fd* -rwxr-xr-x 1 root wheel 76038 Mar 16 2024 bcm2712-rpi-5-b.dtb* -rwxr-xr-x 1 root wheel 331 Mar 16 2024 config.txt*
umount するでござる。
# cd # umount /mnt
カードリーダーを計算機から取り外し、カードリーダーから micro-SD カード を取り外し、その micro-SD カードを Raspberry Pi 5 の micro-SD カードス ロットに差し込むでござる。
次に、 NetBSD-10 の OS のイメージをダウンロードするでござる。

ダウンロードされたファイルは以下のものでござる。
% ls -lF arm64.img.gz -rw-r--r-- 1 daisuke wheel 401164456 Apr 9 15:27 arm64.img.gz
gunzip をつかて圧縮を解いておくでござる。
% gunzip arm64.img.gz % ls -lF arm64.img -rw-r--r-- 1 daisuke wheel 1586495488 Apr 9 15:27 arm64.img
USB 接続の外付け SSD を用意し、計算機の USB ポートにつなぐでござる。
# dmesg | tail -3 [ 4181125.688340] sd0: fabricating a geometry [ 4181125.688340] sd0: GPT GUID: 4a3af2d6-b658-4266-9f60-1339f88640b2 [ 4181125.688340] dk6 at sd0: "11bef65d-0835-4624-b837-dd52e7d9f6d0", 1000215103 blocks at 80, type: ffs
USB 接続の外付け SSD は sd0 として見えているので、 sd0 に dd を使って arm64.img を書き込むでござる。
# dd if=/tmp/rpi5/arm64.img of=/dev/rsd0d bs=1m 1513+0 records in 1513+0 records out 1586495488 bytes transferred in 48.023 secs (33036159 bytes/sec)
dd による書き込みが終わったら、外付け SSD を計算機から取り外し、再び計 算機に取り付けるでござる。
# dmesg | tail -4 [ 4181401.609613] sd0: fabricating a geometry [ 4181401.619613] sd0: GPT GUID: 4bdc5ada-97af-4a16-aaae-f27d86309237 [ 4181401.619613] dk6 at sd0: "EFI", 163840 blocks at 32768, type: msdos [ 4181401.619613] dk7 at sd0: "netbsd-root", 2899968 blocks at 196608, type: ffs
arm64.img が期待通りに SSD に書き込まれたようでござる。 SSD を取り外し、 その SSD を Raspberry Pi 5 に取り付けるでござる。
Raspberry Pi 5 の電源を入れれば、 NetBSD-10 が起動するでござる。
