Raspberry PI firmware version 固件版本怎么查看

 

if you're running Raspberry Pi OS, the tools are native and reliable. Here's the precise, no-nonsense method for checking your Raspberry Pi 4B's firmware versions and ensuring everything is up-to-date.

🔍 STEP-BY-STEP CHECK (Raspberry Pi OS)

✅ 1. Check Current Bootloader and USB Firmware Versions

Run:

sudo rpi-eeprom-update

Expected output:

BOOTLOADER: up-to-date
   CURRENT: Thu 16 May 2024 03:25:17 PM UTC (1715867117)
    LATEST: Thu 16 May 2024 03:25:17 PM UTC (1715867117)
   RELEASE: stable
    VL805: up-to-date
   CURRENT: 000138c0
    LATEST: 000138c0

This tells you both the bootloader and VL805 (USB controller) firmware versions.

---

✅ 2. Cross-Check Actual Bootloader Version

Run:

vcgencmd bootloader_version

Example output:

May 16 2024 15:25:17
version 44b50089e6cbecce84a4b457ef3f6c2547dcf8b8 (release)
timestamp 0

Confirms the actual EEPROM contents. It should match what rpi-eeprom-update reports.

---

✅ 3. Ensure Firmware is Up-to-Date

Run:

sudo rpi-eeprom-update -a

This will:

• Automatically download the latest firmware (if available).

• Queue it for update on next reboot.

If it says "up-to-date," you're good.

---

✅ 4. Reboot to Apply (If Needed)

If an update was staged:

sudo reboot

---

⚙️ Optional Config Review

Check if you're on the stable firmware channel (recommended unless you're debugging):

cat /etc/default/rpi-eeprom-update

Should contain:

FIRMWARE_RELEASE_STATUS="stable"

If you want to switch to beta or critical, change this and rerun the update tool.

---

🧠 If You're a Control Freak

To manually flash a specific firmware version:

1. Download firmware from GitHub: raspberrypi/rpi-eeprom.

2. Use:

sudo rpi-eeprom-update -f ./pieeprom-2024-05-16.bin

Then reboot.

Let me know if you want to script regular checks, enable/disable automatic updates, or go bleeding-edge.
