3.初期設定（Raspberry Pi)

　初期設定

１。MVMEの設定最適化

これを行わないとハングアップする可能性がある

2.

EEPROM更新

sudo rpi-eeprom-update

sudo rpi-eeprom-update -a

sudo reboot

sudo apt install rpi-eeprom

sudo rpi-eeprom-update

sudo rpi-eeprom-update -a

sudo reboot

ブート順序確認

vcgencmd bootloader_config

sudo -E rpi-eeprom-config --edit

[all]

BOOT_UART=1

BOOT_ORDER=0xf416

PCIE_PROBE=1

NET_INSTALL_AT_POWER_ON=0

にする

② NVMe が認識されているか確認

lsblk

③ Ubuntu 側の最適化

sudo nano /etc/fstab

LABEL=writable  /       ext4    defaults        0       1

LABEL=system-boot       /boot/firmware  vfat    defaults        0       1

変更する

LABEL=writable  /  ext4  defaults,noatime,commit=60  0  1

LABEL=system-boot  /boot/firmware  vfat  defaults,noatime  0  0

書いた後

sudo update-initramfs -u

sudo reboot

再起動後確認

 mount | grep ' / '

で下記表示

/dev/nvme0n1p2 on / type ext4 (rw,noatime,commit=60)

I/O scheduler

cat /sys/block/nvme0n1/queue/scheduler

下記表示

[none] mq-deadline

swap（zram推奨）

 sudo apt install zram-tools

確認：

swapon --show

表示

NAME       TYPE      SIZE USED PRIO

/dev/zram0 partition 256M   0B  100

✔ initramfs 更新忘れ注意

fstab 変更後：

sudo update-initramfs -u

電源不足チェック

vcgencmd get_throttled

下記表示でOK

throttled=0x0

NVMEの状態確認
