If I'm going to remove this [pi4] line, the boot-up process is very slow. Slow in a sense that some extended time is observed as compared to the default. I already tested emphasizing the boot_delay=1 but to no avail. The reason why I removed it is because I want to change the settings of the HDMI display resolution as changes will not take effect with the [pi4] line in RPi 3B. > > With 14.0-CURRENT (February 24, 2022 snapshot) I have described my resolution here https://lists.freebsd.org/archives/freebsd-arm/2022-February/001070.html however with the latest 14.0-CURRENT (March 10, 2022 snapshot) it's no longer possible.

You have the option of listing a [pi3] section last (after the [pi4] section). To have a [pi3] section be last, it should have an explicit armstub=armstub8.bin line. Listing older RPi* models last is done because some older RPi models ignore the [] notation and listing things last overrides earlier assignments, in this case overriding assignments for newer models. It is a safe notational ordering convention, even for models that do support the [] notation sufficiently. If one depended on RPi3 models processing [] notation, if it does, then another option would have been to move the [rpi4] line to be just before the armstub=armstub8-gic.bin line, causing the RPi3 to skip the assignment and use the default. === Mark Millard marklmi at yahoo.com
