Raspberry Pi 5: New firmware update brings big improvements

Rasperry Pi 5

Once the SBC, their development continues, either with software or firmware updates, as in this case. Now the Raspberry Pi 5 has received a new firmware update (EEPROM) on April 17 of this year, and it is one of the most important updates since its launch, with important improvements.

La Updating this firmware is simple from the Raspberry Pi OS operating system (formerly Raspbian), since with a few simple commands you can obtain the latest version of the code that will be stored in the EEPROM type memory of your board, with all the new improvements and functions available for your Raspberry Pi 5.

To update, you just have to run the following script:

sudo apt update
sudo apt upgrade
sudo rpi-eeprom-update -a

EEPROM 17/04/2024: Improvements included for the Rasbperry Pi 5

The Raspberry Pi Foundation has released this new firmware update for the Raspberry Pi 5 that includes important improvements, being one of the largest updates to date. Between the improvements we have:

  • Improved performance: In this update for the EEPROM of the Raspberry Pi 5, performance has been improved, optimizing the management of SDRAM memory usage, dynamically adjusting the clock frequency based on temperature changes, guaranteeing stable operation even with workloads quite demanding, reducing cases of unexpected behavior and with smoother performance regardless of the 4GB or 8GB configuration you have chosen. For overclocking enthusiasts, this update also improves this aspect, being able to take the processor up to 3 Ghz. Finally, overall memory efficiency has also been improved by reallocating non-essential kernel stages to a dedicated 512 KB space, freeing up a good chunk of memory for other processes.
  • Stronger security- Security is paramount in today's digital world, and the EEPROM upgrade prioritizes this aspect. The update introduces support for custom CA (Certification Authority) certificates with HTTPS boot. This allows users to implement their own trusted certificates for secure boot, adding an extra layer of protection against unauthorized access. Additionally, the update fixes vulnerabilities related to the TRYBOOT functionality when secure boot is enabled. These fixes address potential security exploits that could compromise the system. With these improvements, users can rest assured that their Raspberry Pi 5 is better protected against potential threats.
  • Better hardware compatibility- Also expands the capabilities of Raspberry Pi 5 by improving its compatibility with external hardware. The update provides improved support for HAT+ (Hardware Attached on Top) and NVMe (Non-Volatile Memory Express) devices. This allows users to connect a wider range of peripherals and accessories, opening doors to more diverse applications. Whether you're working on Internet of Things (IoT) projects, building a powerful media center, or developing custom applications, improved support for HAT+ and NVMe devices allows for greater flexibility and customization.
  • USB improvements- The Raspberry Pi 5 update offers notable performance improvements, particularly in terms of USB write speeds. Faster data transfer times speed up tasks that involve frequent data movement, such as copying large files or working with external storage devices. This results in a more efficient workflow and a more responsive user experience. Looking ahead, the update also lays the groundwork for future advancements. The inclusion of preliminary support for D0 (Device State 0) and CM5 (Compute Module 5) configurations signifies the Raspberry Pi Foundation's commitment to future-proofing the device. This allows the Raspberry Pi 5 to adapt to emerging technologies and remain compatible with new hardware developments.
  • Other: Of course, there is also room for other improvements in this Raspberry Pi 5 firmware update, such as the correction of some bugs, code optimizations, and even some improvements for installing operating systems from the network, a feature that already It was introduced in the previous EEPROM update.
