Building a new SD card

[linuxha]

I'm trying to get my RockPro64 onto a new SD card. Under Linux, as root I run:

7z x ./Armbian_20.02.1_Rockpro64_buster_legacy_4.4.213.7z
./balenaEtcher-1.5.70-x64.AppImage ./Armbian_20.02.1_Rockpro64_buster_legacy_4.4.213.img

When done, my SD looks like this:

root@mozart:/home/njc/dev/taz# fdisk -l /dev/sdc
Disk /dev/sdc: 14.9 GiB, 15931539456 bytes, 31116288 sectors
Disk model: Card  Reader    
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x019a33bc

Device     Boot Start     End Sectors  Size Id Type
/dev/sdc1       32768 2899967 2867200  1.4G 83 Linux
root@mozart:/home/njc/dev/taz# 

I then put it into the RockPro64, power it up and I see nothing. I have no WiFi and the console doesn't spit out anything.

The old SD card that still boots (but with an OS that is very unstable) has:

njc@taz:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            1.9G     0  1.9G   0% /dev
tmpfs           388M  5.4M  383M   2% /run
/dev/sda2       1.8T   35G  1.7T   2% /
tmpfs           1.9G     0  1.9G   0% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
/dev/mmcblk0p6  112M  4.0K  112M   1% /boot/efi
tmpfs           388M     0  388M   0% /run/user/1001
njc@taz:~$ 

Is this enough information to figure out what is wrong?

I've upgraded SDs with x86, Pi and Toradex but the RockPro64 is giving me no end of fits.

Hi,

are you sure your new SD ist not broken.
Why not make a copy using dd or ddrescue of
The good SD to a file for backup purpose and
copy the new OS on that SD, maybe that works.

Nope, 100% positive, SD is good, computer is also good.

I was poking around the site when I noticed on the front page (who read that ... ;-) ) and found that there is an official version of Debian. So I followed the links, zcat'd the images together and etcher'd the image to the same SD card. Not only did it boot, I now have serial port access at 1500000 (1.5Mbaud - sure beat the 110 baud I started out with decades ago).
