I guess so. If I understand correctly all these chips are EOL, maybe they can't get the other ones anymore.

Received another T3+ from FriendlyArm (ordered 2 weeks ago). This time the chip is SEC 907 K4B4G16 46E BCMA and it works with the edited image :-)

Value that changed in bl1 is frequency. 666MHz
Original frequency was 800MHz
Interesting. What speed is it using in the NanoPC-T3 image (the non + image)? That has been quite stable for me so far.

I'll try to test this later this week. @Vlado it looks like you have the same chip as @Igor but you needed the edit where he didn't which is odd. On his board the chip was printed SAMSUNG 728.
YES, same as Igor SAMSUNG 728 K4B4G16 46D-BCK0
PCB also same!
Pretty strange then - sometimes your edit is needed and sometimes not!

Going back through this thread then, here's what we have so far:
User Chip Works Igor, Vlado SAMSUNG 728 K4B4G16 46D-BCK0 Yes (sometimes with, sometimes without bl1 edit - WTF??) constantius SEC 710 K4B4G16 46E-???? Yes (needs bl1 edit) sfalcon, AmirHG SEC 710 K4B4G16 46E-BCK0 Yes (needs bl1 edit) crazystick SEC 843 K4B4G16 46E BCMA Yes (needs bl1 edit) crazystick SEC 907 K4B4G16 46E BCMA Yes (needs bl1 edit)
I'll try to test this later this week. @Vlado it looks like you have the same chip as @Igor but you needed the edit where he didn't which is odd. On his board the chip was printed SAMSUNG 728. Is it the same for you? @constantius would be good to fill in the ???s just for completeness.

So, NOW it work!!!
Armbian 64 2GB on T3+
Can you post a photo of your board showing memory chip P/N?
-
@Matthew Harding I think I tried those already. I think one of them also can't boot from eMMC and the other was on a 3.x kernel and some other peripheral didn't work for me. Please post an update here if one of those images does work for you. In the meantime fingers crossed someone can figure out how to make this work in Armbian, it's unfortunately beyond my skills.

To be fair Matthew, there don't seem to be any images for this board that can boot from eMMC that are actually being maintained. It's sad, but unfortunately it seems like it's a pretty normal problem for all these boards. There are often problems with one bit of hardware or another. Sometimes the manufacturer supplied image is working, but then you're probably stuck on an old kernel or the image comes with tons of stuff that you don't need. Still searching for the holy grail of a board that is cheap, well built and can boot from eMMC. I really wanted it to be Pine, but so far the closest is the NanoPC-T3+ although you can only run the Armbian image for the T3 and you lose half the RAM :-( Still half the RAM is better than not booting at all.
-
I have the same problem, and another chip SEC 843... with the same board revision. Looks like the working chip might be the one-off here :-(
I can also confirm as others have reported that the image for the T3 (non-plus) boots fine but only exposes 1GB memory.

Did you ever manage to get the Pine to boot from eMMC?

Just a little note to say that the `nand-sata-install` script doesn't transfer an edited bl1 from the SD to onboard eMMC, so you need to reapply the edit. If you only have CLI, you can do it like this (assuming you've booted from SD and run nand-sata-install already):
