It's like air. While he is there, he is not noticed. It's gone and the "coffee makers" are starting to glitch in different corners

ok.. I am not sure I follow. Probably its again caused by the translator messing up the description, but still could you please try explaining with less metaphors and more simple language.

@goingI'm on Armbian 24.2:

I did not immediately notice (drew attention to) the fact that in the logs posted in both topics you can find messages about the missing Internet.

 

The voltage was applied to the device.

When booting, system services try to reach the time server and set the current date and time.

They can't do it and the system ends up in the past. A system failure is occurring. And as a result, a reboot.

You and I cannot know on which images the system services are working correctly, and in which cases a failure occurs.

In my memory, this part of the functionality has changed.

 

I remember that there was a script that remembered the current time before shutdown and restored it by adding one hour.

For me your comments don't fit to this thread...

 

Do these images work for your BPI? Is there an internet connection when you launch them?

When you run your BPI on your current image without going online, is there normal operation?

Individual settings for the memory chip such as timings, power supply voltage in the uboot bootloader can solve some problems.
Maybe we can compare what is soldered on our boards? @Tu Hu @dd5xl @AaronNGray

datasheet:

[ LPDDR3 ]
* VDD1 = 1.8V (1.7V to 1.95V)
* VDD2, VDDCA and VDDQ = 1.2V (1.14V to 1.30)
* HSUL_12 interface (High Speed Unterminated Logic 1.2V

datasheet;

e·MMC consists of NAND flash and a MMC controller.
3V supply voltage is required for the NAND area (VDDF) whereas 1.8V or 3V dual supply voltage (VDD)
is supported for the MMC controller.
Maximum MMC interface frequency of 200MHz and maximum bus widths of 8 bit are supported

 MMC I/F Clock Frequency : 0 ~ 200MHz 
 MMC I/F Boot Frequency   : 0 ~ 52MHz

 Temperature : Operation(-25C ~ 85C), Storage without operation (-40C ~ 85C)
 Power  : Interface power → VDD  (1.70V ~ 1.95V or 2.7V ~ 3.6V),
          Memory    power → VDDF (2.7V ~ 3.6V)

My DDRAM is "H9CCNNNBJTMLARNUM" where according to the datasheet the B" should be read as a "8" (8GB density).

 

And yes, I've read the specs and voltages as well.
From my experiences any platform has to be tuned in terms of clocks and voltages to become stable. You can't rely e.g. on a PMIC delivering exactly the voltages as programmed in the registers due to chip variations and PCB layout constraints.

 

Its not the programmed value but the effective voltage at the consuming chip which makes the difference.

Absolute agreement. And this is part of the user's research.

A millivoltmeter and knowledge of the measuring point is something that cannot be programmed and provided.

@going i tested Armbian_23.10_Bananapim3_bookworm_edge_6.4.10_minimal.zip, it works also on my borad, but if i change the language from RU to US, then dead😵‍💫

Armbian_23.10_Bananapim3_bookworm_edge_6.4.16_minimal.img doesn't work at all on my board.

If your SD card is working properly and the image is recorded on it correctly, then this is the reason:

This image differs from the previous one in that in the uboot configuration the parameter 'CONFIG_DRAM_CLK=480'.

This only means that your board needs 'CONFIG_DRAM_CLK=384' - this is what is set by default in the current Armbian images.

 

Unfortunately, you have not published what exactly does not work.

Maybe a system startup log?

Maybe a set of commands that you used to switch the locale language?
