How can I check how many RAM is active on my router? free gives me this:
root@Router_VPN:~# free
total used free shared buff/cache available
Mem: 253720 33664 207504 372 12552 190728
Swap: 0 0 0
So I think I just use 256MB of the RAM? Should be 512MB, right?
I use the 21.02.1 OpenWrt (Full Image, not the legacy)
You showed us already.
You don't mention the device...also you don't explain why you believe the device has 512 - instead of 256 MBs of RAM.
Perhaps...you could clearly explain why you asked how much memory you have...proceeded to show us the memory...then told us you have 512 MB or RAM???
Is there some issue???
???
Does this mean x68_64???
(Please provide more information.)
EDIT (didn't see the model in the title): Yes, the data page says 512.
ok, good to know that I found out that i have not enough Memory activated. I know this router comes with a Vendors OpenWRT 14.07 what also dosen't give you the full 512MB RAM. But i also thought, flashing the full Image should fix this problem like explaned in the wiki:
Which full image exactly have you flashed?
From the wiki:
If it's important; I flashed it with SP Flash Tool like explained in the wiki under debricking.
@dwmw2 has written the instructions in the wiki, maybe he can help?
Can you show the serial logs as it boots? In particular the bit where the preloader says...
[Dram_Buffer] dram size:1073741824
And U-Boot says...
U-Boot 2021.10 (Jan 10 2022 - 13:45:41 +0000)
CPU: MediaTek MT7623 E3
DRAM: 1 GiB
... and then Linux says:
[ 0.000000] Zone ranges:
[ 0.000000] Normal [mem 0x0000000080000000-0x00000000afffffff]
[ 0.000000] HighMem [mem 0x00000000b0000000-0x00000000bfffffff]
Just to make sure: I need to connect to the serial port during booting? Or is ther any log file i can read through ssh?
Well, we could start with the kernel messages from dmesg and the contents of the memory nodes from /proc/device-tree, but I suspect they won't tell us anything that we don't already know; that by the time the kernel boots, it is only aware of 256KiB of RAM.
The preloader actually does the detection, and passes that information to U-Boot, which then puts it in the DT for the kernel when it boots.
Got it connected to the serial:

and linux say with dmesg

I don't see any "Zone ranges:" in serial Log or Dmesg
OK, so you have 1GiB of RAM and Linux knows that (262144 * 4KiB pages).
So why isn't Linux using them all? Do you have a mem= argument on the command line? Can you show the rest of the dmesg too?

Hm, that kernel definitely thinks it has 1GiB of RAM. Can you run free again?
root@Router_LTE:~# free
total used free shared buff/cache available
Mem: 1028520 35428 953144 84 39948 937252
Swap: 0 0 0
root@Router_LTE:~#
Now i'm totaly confused... Why it changed from one minute to another??? The dmesg I sent you in the last post, I did't two minutes later than the free in my first post...
but anyway I'm more confused about the value "1GiB". Is it the same like 512MB???
WOW... I found my mistake... littel bit awkward for me...
I have two diffent routers in my Network... One (Xiaomi Mi Router 3G) only have 256Mb of RAM... I'm just made a typo in the IP-Adress by Signing in with putty...
Sorry for that and Thanks for spending your time for my stupidity.
Ummmm no, 1 GiB is 1 GiB and 512 MB is 512 MB...
Glad you sorted it out.
No, 1GiB is twice as much as 512MiB.
Remember, 'b' means bits, 'B' means bytes.
Until the 1990s there were only the SI decimal prefixes including 'k' which means 1000, 'M' for 1000000, 'G' for 1000000000 etc., and 'm' for 1/1000 (one thousandth).
In 1998 the IEC standardised the binary prefixes including 'Ki' for 1024 (2¹⁰), 'Mi' for 1048576 (2²⁰), Gi for 1073741824 (2³⁰) etc.
So...
1b is one bit, an eighth of a byte.
1B is 8 bits, one byte.
1kb is 1000 bits, 250 bytes.
1Kib is 1024 bits, 256 bytes.
1kB is 8000 bits, 1000 bytes.
1KiB is 8192 bits, 1024 bytes.
512MB is 512000000 bytes.
512MiB is 536870912 bytes, precisely half of one GiB.
512mb is 512 millibits, so a little over half a bit.
1Gib is 1073741824 bits, 134217728 bytes or 128KiB.
1GiB is 1073741824 bytes.
Your board, like mine, has 1GiB of memory rather than the 512KiB of memory that the documentation suggests.
Thank you again for the detailed clarification. I hope this also helps other person to understand there System.
