That Copyright date does not tell you the vintage: The RPi4B Rev 1.5 "C0T" wtih 8 GiBytes also lists 2018. Capture the early serial console output from the RPi* bootloader and firmware and look for lines that contain one of (showing a 8 GiByte Rev 1.5 example: d03115): boardrev d03115 0x00d03115 RPI 4 Model B (0xd03115) That last is actually from U-Boot. The first was toward the end of the "BOOTMODE:" line. The middle was the line after the "Read fixup4.dat bytes" line. By contrast a 4GiByte Rev 1.1 has for those lines: boardrev c03111 0x00c03111 RPI 4 Model B (0xc03111) >> Using a Rev 1.5 (so: "C0T", not "B0T") . . . >> > Guess my Pi4 is likely "BOT", given the age. > > After a lot of hair-pulling it turns out I didn't > connect the usb-serial ground wire..... > Now the machine boots > FreeBSD-14.1-RELEASE-arm64-aarch64-RPI.img > with no problem. > > I think the original problem was likely a bungled > dd operation.
