I have been using uboot V2025.04(2025-snuxi) on orangepi zero2w since 19 April and everything is works as it should no problems.

During the first few boots on my Orange Pi Zero 3 1GB, RAM size seemed to be detected correctly. Yesterday I saw RAM size being reported as 2GB, also after a reboot.

As soon as the fixed U-Boot is available to  install I am happy to provide test results or other test procedures when needed!

I have a custom build running to try u-boot 2025.4, some warnings about "no previous prototype for..." are given, for example:

 

[🔨]   drivers/net/wireless/rtl8192eu/hal/phydm/phydm.c:434:6: warning: no previous prototype for 'phydm_common_info_self_reset' [-Wmissing-prototypes]
[🔨]     434 | void phydm_common_info_self_reset(struct dm_struct *dm)
[🔨]         |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
[🔨]   drivers/net/wireless/rtl8192eu/hal/phydm/phydm.c:477:6: warning: no previous prototype for 'phydm_phy_info_update' [-Wmissing-prototypes]
[🔨]     477 | void phydm_phy_info_update(struct dm_struct *dm)

 

Is this just a warning or do I need to supply extra info/libraries to build without those warnings?

drivers/net/wireless/rtl8192eu/hal/phydm/phydm.c seems like a linux source file... maybe this warning was shown AFTER uboot finished compiling?

[boyd86]

From what I understood, yes this was after u-boot compilation. https://paste.armbian.eu/hilijogore.bash contains the log, there is no img file in the output directory.

Before I ran ./compile.sh I added BOOTBRANCH="tag:v2025.04" and BOOTPATCHDIR="v2025.04" to config/boards/orangepizero3.csc.

In the final lines of your build log output, it seems that it cant download some ubuntu packages.

 

I dont see linux compilation errors (I only looked at it for 1 minute).

 

Can you try rebuilding with debian?

[boyd86]

Apparently the compile script or one of its libraries uses a fixed DNS server instead of the DHCP provided one. After disabling some pfSense rules I was able to successfully boot.

However, it seems like still 2GB RAM is incorrectly shown:

 v25.08 rolling for Orange Pi Zero3 running Armbian Linux 6.12.30-current-sunxi64

 Packages:     Debian stable (bookworm)
 Support:      DIY (custom image)
 IPv4:         ---

 Performance:

 Load:         20%              Up time:       1 min
 Memory usage: 7% of 1.93G
 CPU temp:     45°C              Usage of /:   9% of 15G

 

Also, /dev/ttyS1 is not working, I used overlays=uart5 which enabled /dev/ttyS1 correctly using Armbian Debian Minimal image from the Download section. dmesg does not output anything related to ttyS1.

if NAMESERVER is not set it falls back to default 1.1.1.1

 

A while ago I made a hack to enforce using whatever hosts nameserver is:https://github.com/armbian/build/blob/e03b1b543cda430fbffcb62c979aecabee42b044/config/templates/config-example.conf.template#L25

fix:

- run this as root

^ login as root
> wget -O - https://apt.armbian.com/armbian.key | gpg --dearmor -o /usr/share/keyrings/armbian.gpg

 
you should find a file /usr/share/keyrings/armbian.gpg about 2 KB in size

repeat apt update etc should have resolved the error
