The other requirement for USB boot is that you have to be booting Raspberry Pi OS version or later.

If you happen to have an older version, the instructions for updating are given in the USB mass storage boot section of the Raspberry Pi Hardware Documentation. I have three Pi 4 units (with 1GB, 2GB and 4GB of memory) which I got from the first batch available in Switzerland, and all of them have Sep 3 firmware so I assume the older firmware is not very common. There are two ways to do this either remove the microSD card and then boot, so you can read the firmware date from the diagnostic screen, or simply run vcgencmd bootloader_version. It seems that some early bootloader firmware versions did not properly support this, so you have to be sure that your Raspberry Pi 4 has bootloader eeprom firmware dated or later. (I will be writing about that case in my next post.)įirst, as I just said, USB boot is enabled by default on the Pi 4B (and the Pi 400, by the way), but there is a small caveat to that. The reason I have gotten into this, however, is that I recently got a Raspberry Pi 4 case which includes an M.2 SSD adapter, and that drive connects via USB. Another is that USB drives tend to cost less than microSD cards of the same size, and as the storage capacity goes up, the price difference gets larger. The first question to ask, I suppose, would be why is USB boot interesting at all? Well, one good reason I have already mentioned is that a USB 3.0 device is faster than an SD card.

Perhaps it is because of a lack of familiarity with the possibility, or a lack of detailed examples of doing it. So, in theory, USB boot should be gaining in popularity, but it seems to me that is not happening. USB boot is enabled by default, and the Pi 4 has two USB 3.0 ports which make USB mass storage devices noticeably faster than SD cards. The Raspberry Pi 4, however, has fixed both of those problems.
