networking in bpi-m5 with new 26.03.1 release.

/dev/mmcblk0p1 is a partition that contains the filesystem, not a drive. The drive is /dev/mmcblk0 and because you did a low-level sector by sector (or block by block) copy with dd, it also just has the exact same partition table (MBR-table or GPT). 

Now in modern Linux and various pre-installed images there are methods (possible) to expand the partition and the filesystem to occupy the whole remaining space. It is easier with MBR-table. If GPT, there is a backup GPT at the end of the disk, so in your case 64G. On the 128G SD-card the space after 64G is then hidden.

I usually manage all this manually before first boot, with gdisk, not fdisk. As it is text based, it also works via remote ssh and serial console cable. I also deliberately added a dummy partition (number 3) to RPi images in the past so that the auto-expander could not claim the whole SD-card. If no GUI, a Linux install fits within a few GB, especially if you use Btrfs as filesystem for root and use on-the-fly compression (mount option compress-force=zstd). Then it is about 1GB needed, not 100x more.

And the email system for is emailing with me erroneos info about bedno report 2x a day, so call off the quard dogs, it been solved without any help from this forum. you've been yelling about dhcp w/out once offering me a single clue as to how I should configure it even when I showed you the results.  FYI I have been doing odd things with little machines for a lot longer that most of you have been breathing on your own starting with an rca 1802 in 1978.  Do any of you have a track record that long?  That bit of production tooling for a medium market tv station was still in use 20+ times a day when the station burned to the ground in the late 90's.  I prefer to call it efficiency since most production equipment at a tv station is so heavily used & long since worn out before the IRS lets them amortize the cost. I am also a CET, a test 95% of the EE's out there cannot pass. I call a backup server that draws 19 watts at full song in the middle of backing up 8 machines here, efficient. Took me a while to figure it out the hardware and around $1500 in hardware.  But it works as fast as my cat6 wired local net can run.

As a moderator having watched this thread, I'm going to close it down, as I don't think anything else productive will be said at this point.

However I do want to thank both @bedna and @eselarm for their time and effort to help.  Armbian appreciates all the volunteers who make these forums possible.
