G'day all,
I have an old RPI3 running Jessie that I wanted to replace with a 4
(wanted USB3 & GbE)
Not wanting to re-configure or re-install I downloaded the latest
Raspbian for the Pi4 (Buster) to use for parts.
I replaced the boot partition contents straight from the Buster image.
Had to edit cmdline text to alter the root parameter "root=/dev/mmcblk0p2".
Then I simply rsynced /lib/modules and /lib/firmware across to the root
partition (adding not replacing).
It booted right up with USB, net and console functional and I was back
in business on the new hardware.
I don't use the GPU except for initial bringup, nor wlan or bluetooth.
So I can't vouch for those, although udev certainly detects the wlan.
The config.txt lines to disable wlan & bt still work also :
dtoverlay=pi3-disable-bt
dtoverlay=pi3-disable-wifi
Regards,
Brad
I tried what you've described --- put a fresh copy of
"devuan_ascii_2.0.0_arm64_raspi3.img" on an 8GB microSD card, then
copied the parts of Raspbian Buster over; but I end up with an error
"/sbin/init exists, but is not executable (error -8)", possibly
suggesting that there is a mismatch between 32-bit boot code and 64-bit
/sbin/init.
Did you make any other changes?
