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

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: U-Boot SPL 2022.07-armbian (Feb 17 2023 - 23:33:06 +0000) DRAM: 2048 MiB Trying to boot from MMC1 But occasionally (once every 10-20 boots) I get this with the red LED: U-Boot SPL 2022.07-armbian (Feb 17 2023 - 23:33:06 +0000) DRAM: 1024 MiB Trying to boot from MMC1 NOTICE: BL31: v2.8(debug):a84636ad-dirty NOTICE: BL31: Built : 23:33:00, Feb 17 2023 NOTICE: BL31: Detected Allwinner H616 SoC (1823) NOTICE: BL31: Found U-Boot DTB at 0x4a0903e0, model: OrangePi Zero2 INFO: ARM GICv2 driver initialized INFO: Configuring SPC Controller INFO: PMIC: Probing AXP305 on RSB INFO: PMIC: aldo1 voltage: 3.300V INFO: PMIC: aldo2 voltage: 3.300V INFO: PMIC: aldo3 voltage: 3.300V INFO: PMIC: bldo1 voltage: 1.800V INFO: PMIC: bldo2 voltage: 1.800V INFO: PMIC: dcdcd voltage: 1.500V INFO: PMIC: dcdce voltage: 3.300V INFO: BL31: Platform setup done INFO: BL31: Initializing runtime services INFO: BL31: cortex_a53: CPU workaround for 855873 was applied INFO: BL31: cortex_a53: CPU workaround for 1530924 was applied INFO: PSCI: Suspend is unavailable INFO: BL31: Preparing for EL3 exit to normal world INFO: Entry point address = 0x4a000000 INFO: SPSR = 0x3c9 INFO: Changed devicetree.

Retrieving file: pxelinux.cfg/00000000 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.
