The Raspberry Pi 4 will start receiving an important firmware update that will make the process of booting and installing an operating system much easier. This week the Raspberry Foundation announced the arrival of USB boot support, which will greatly increase the possibilities of how you turn on your Pi 4.
O Raspberry Pi 4 was launched in June last year with support for 4K and up to 4GB of RAM. But, despite its four USB ports – two 2.0 and two 3.0 – the small device did not support USB Bootloader and restricted its boot to the use of a microSD card, for example. So this news of firmware update is being very well received by the community, almost a year after its release.
Computer maintains same value as 8 years ago, but with twice as much RAM
The updatel, however, is still in beta, so it needs to be done manually. Anyone interested will need to load the latest version of the Raspbian operating system on a microSD card and update the firmware on a dedicated terminal. Then just restart the Raspberry Pi 4 with the card and the new USB Bootloader should now work.
To go deeper into the settings of the USB Bootloader on Pi 4 check the details in official Raspberry website.
