[Orange Pi Zero 2 v1.5 not booting on kernel 6.1.4]

The main hardware differences I see are the RAM moving and a lot less supporting passive components, which makes me wonder if the v1.5 is a "value-engineered" model.

 

Thanks for the update! I should have clarified, since there are builds that work on my boards I'm not necessarily looking for a solution, just trying to provide some helpful (hopefully) datapoints. I'm happy to help test as needed, I have some development experience, but I haven't done any tinkering with kernels and u-boot in quite a while

[Orange Pi Zero 2 v1.5 not booting on kernel 6.1.4]

Thanks for everyone's work on this project! 

 

I'm working on a few Orange Pi Zero 2 v1.5's, and they won't finish booting on a few of the most recent images. (Just testing jammy right now to keep things consistent)

 

Boot Successfully:

• Armbian_22.11.3_Orangepizero2_jammy_edge_6.1.4
• Armbian_22.05.3_Orangepizero2_jammy_edge_5.17.11

Do Not Boot Successfully:

• Armbian_23.02.2_Orangepizero2_jammy_edge_6.1.11
• Armbian_22.11.1_Orangepizero2_jammy_edge_6.0.10
• Armbian_22.08.7_Orangepizero2_jammy_edge_5.19.16

 

Typically, when the boot fails, all I get is this over serial with no LED's:

But occasionally (once every 10-20 boots) I get this with the red LED:

I've read most of the other posts about this board, and I'm curious if there's some kind of difference in the v1.5 HW. It seems like v1.5 seems to have more issues, and there are significant visual differences (v1.5, v1.2). Unfortunately OrangePi only published schematics for v1.3, so I'm not sure how to tell what exactly would have changed.
