OK, thanks for the help Werner

There appears to be no provision for eMMC on the OrangePi PC2. Yes this image is about 2 years old and only works on my older OrangePi PC2. The images that do work on my two newer OrangePi PC2 boards both are using 2019.10 U-Boot.

I increased boot verbosity to 7 and this is the output on my serial console: <\r><\n> U-Boot SPL 2018.11-armbian (Feb 08 2019 - 11:25:48 +0100)<\r><\n> DRAM: 1024 MiB<\r><\n> Trying to boot from MMC1<\r><\n>

Hi all, I bought a Orange Pi PC 2 a year or two back, loaded the Armbian image successfully and tweaked it until it was just right for my application. As this piece of hardware was going to live on a remote property, I bought another 2 Orange Pi PC 2 boards and some new SD cards with the intention of having 2 backups - one for development and the other as spare. I loaded these two up with the latest Armbian image and configured them as needed. These two work fine, even if I swap the SD card between these two pieces of hardware. However, when I try to put the SD card from the original Orange Pi PC 2 into one of the newer Orange Pi PC 2 it will not boot. I can see on the UART console that it is trying to start the kernel but just hangs. These are all the same hardware: They are all Orange Pi PC 2's and even the board revision printed in the silkscreen is the same. So it makes no sense why certain SD cards work for some hardware and not others. Can anyone think of why this might be happening? I am thinking I have missed something really simple, so please give me all the advice you can - even if it is really basic. Many thanks to you all in advance.

Thanks Igor, I thought it would be something simple like that. Can you tell me more about where the bootloader is written. I am assuming it is in the 16MB of unallocated space before the active partition. (I have a keen interest into disks/storage and how data exists on them)

One more thing that I should add; I can successfully clone a new vanilla image from the Armbian website onto the new SD cards. This image boots up and works fine. The only downside is that it doesn't have any of the tweaks I need (and that took me forever to get right the first time).

Hi all, I bought a Orange Pi PC 2 a couple of months back, loaded the Armbian image successfully and tweaked it until it was just right for my application. As this piece of hardware was going to live on a remote property, I bought another 2 Orange Pi PC 2 boards and some new SD cards with the intention of having 2 backups - one for development and the other as spare. I cloned the SD card by copying the active EXT4 partition across to the blank SD card using GParted. The long and the short of it is that these images did not work. I know the hardware is good as the original SD card works in the new OPi PC2 boards. Likewise the new cards don't work in the original OPi PC2. When I put the new SD card into the the OPi PC2 and powered it up, I get an unresponsive board. Nothing comes up on the HDMI screen, the green LED onboard does not light up after a few seconds like the working system. I have even gone so far as putting a UART to USB on the board. On the original, I get the usual Linux startup text. You guessed it, with new SD cards, I don't get anything. So what is different, the new SD cards are a different brand to the original. Original was Samsung. Now using Kingston. The original hardware is now deployed at the remote site. Be fore I deployed, I made an copy of the active partition and put it on a spare HDD. I hope this partition is all I need. I am thinking I have missed something really simple, so please give me all the advice you can - even if it is really basic. Many thanks to you all in advance.
