This is a common Linux issue and we usually do not provide assistance. But you have interested me in this fact. If I understood correctly, then the same SSD drive connected via the SATA connector - trim mode is possible, and connected via a USB-SATA adapter - trim mode is impossible? Publish the DMESG output of the line where the USB-SATA adapter is defined. I have a lot of these things. I'll check it out.

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.

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 My board: Bpi-M3 v1.1 ___________ AXP813 ___________ RTL8211E _______________ SUMSUNG 319 KLM8G1GEAC-B001 _______________ SKhynix H9CCNNNBJTML ARNUM 521A UTMBA023HA _______________

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?
-
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.

It seems that the reason is the lack of Internet access. 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

@dd5xl Igor, what kind of kernel is working at the same time? I don't see any temperature readings. What is the value of the CONFIG_DRAM_CLK parameter ?

None of the images work.. OrangePi Zero2

You won't believe it, but sometimes it seems to me that artificial intelligence begins to mock my messages. I apologize. -

A search for Ali on the FTDI232 line yielded 216 results. Is that not enough? -
A short comment on the discussion. I never use armbian-config. It doesn't help me figure out the essence of the problem. I am considering the overlays that are provided by Armbian as a template for possible use. A script that switches something can be harmful. I'm just turning it off. Next, I pull out the DTB from the working system, which was actually applied. I open the schematic diagram of the printed circuit board and the schematic diagram of the device that I want to attach to the board. I write out the available pin numbers in the table that I could use. I take an overlay file found on the Internet or an existing one as a basis and rewrite it to suit my needs. Next, compile this file, add it to the download and check its operability. This algorithm ensures that nothing superfluous appears in the applied device tree. We can add a lot of automation. We can even connect neural networks to recognize circuit diagrams.😁 But an experienced user will still try to get around (ignore) all this. And an inexperienced user will not understand why something is not working for him. He just did not extract the DTB from the running OS and he does not see the real state of things. It seems to me that helping the user to start thinking with his own head is the best solution.

When the maintainer regularly updates the kernel configuration file in the source repository, you can rely on the correctness of this file. Unfortunately, I did not do this. Until now, this repository was only my personal one and I didn't need to follow some rules to publish. My pbs-master branch was created from the master branch, which is now abandoned and not being developed. I just continued to develop it and added 118 commits on top. There are no mistakes in this. This download script sets up the carl program to be very chatty.

Sometimes there may be large files in the root (/*). sometimes a lot of files can accumulate in the /var folder, for example, in the apt cache. Just go through them all. Run the 'mc' command. Go to the root of the file system. - find "show size" in the menu. Find the folder with the maximum size. Go to it. Repeat "show size"

If you downloaded a banana from the SD card and a failure occurred, simply turn off the device, take out the SD card and connect it to a Linux computer via the adapter. Find the latest system logs and review them.

Does not seem to build for me on Ubuntu-22.04.3 LTS git pull cp config/templates/config-test.conf userpatches/ ./compile.sh test BUILD_ONLY=default

As far as I know, the default system cross compiler is used today. Try using the key SKIP_EXTERNAL_TOOLCHAINS=no What is the difference? You can check it out: ${prefix}-gcc -v In this particular case, it's my human eye and pressing the mouse button. If the eye has noticed the difference, it is already significant. Switching the processor frequency with increasing load (when a resource-intensive process is started) is faster.

I have a question. If it works well, why switch to another interface (Ethernet)? This device does not have a battery-powered clock and it requires the Internet to get an accurate time stamp from the time server and set the SOC's internal clock in real time. You have disabled WI-FI and connected Ethernet. Do the settings in the connection management system look correct now? Is the network cable working? Does the banana receive the DHCP settings from the router? Did the router have Internet access at the time of banana connection? You didn't write anything about it. Just for reference. There has been a strong magnetic storm on our planet for the last two days. My Internet went down several times for one hour or more.
-
Boot the system in the case when it is stable, i.e. with wi-fi. Look at the system logs and post the one when the Ethernet connection failed.
-
Maybe yes, maybe not if there are smart devices on both ends. I have all the cables full. The device itself decides how many lines to use. dwmac-sun8i 1c30000.ethernet end0: Link is Up - 100Mbps/Full - flow control rx/tx There is an inscription on the switch: 10/100 Fast Ethernet switch
-
All my boards are connected by cable to an Ethernet switch. And it is connected to the router accordingly The switch is old and it is 10mbit slow. I did not perform a health check at a speed of 1 Gbit.
-
Almost all of these little rafts won't work without the internet. The reason is the lack of a watch with a battery. The OS finds itself in the past and thinks that the file system is corrupted because the timestamps of the files are from the future.
