RaspiOS adds more text at the end. Using a RPi4B example that is running RaspiOS64 (their Debian with 64-bit world and kernel): # cat /proc/cpuinfo processor : 0 BogoMIPS : 108.00 Features : fp asimd evtstrm crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd08 CPU revision : 3 processor : 1 BogoMIPS : 108.00 Features : fp asimd evtstrm crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd08 CPU revision : 3 processor : 2 BogoMIPS : 108.00 Features : fp asimd evtstrm crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd08 CPU revision : 3 processor : 3 BogoMIPS : 108.00 Features : fp asimd evtstrm crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd08 CPU revision : 3 Hardware : BCM2835 Revision : d03114 Serial : REPLACED Model : Raspberry Pi 4 Model B Rev 1.4 The "Hardware" is misleading (and documented to be so) but the Revision and Model are appropriate above. That also worked on ubuntu, but not on Fedora 34. All 3 support: # cat /sys/firmware/devicetree/base/model but there is no new-line at the end. If vcgencmd is present and operational: # vcgencmd otp_dump | grep 30: should work to find the revision code. But it failed to initialize on Fedora 34. (All this testing is on RPi4B's.) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
