Real memory question
-
Hello fellow Netgate community members,
Is this correct for the 2100?
I thought the real memory was 4GB the values are showing this on boot up…
-
I know ARC and top show the actual full memory but I can never get them to add up to the correct binary memory value.
-
-
My goal is to get it to add up to 4GB binary value. Anyone ever try to do that?

Yes, that's the expected value in the 2100:
real memory = 3602862080 (3435 MB) avail memory = 3462533120 (3302 MB)The memory map from the SoC provides 32bit access so it sees 3.6GB.

Anyone else know any wicked ram memory commands for freeBSD let me know.

Hello!
Something like...
dmidecode -t memory | egrep "Maximum Capacity|Number Of Devices|Size|Type:"...can be useful.

Oooo this one is good too
grep memory off of a sysctl -a....

@serbus said in Real memory question:
dmidecode -t memory | egrep "Maximum Capacity|Number Of Devices|Size|Type:"
Dang that one didn't work on arm for me

and you got your GUI monitor nice one..

There are some things you can see from uboot. Firstly that at boot it reports:
Model: Silicom Rogue-2 CPU 1200 [MHz] L2 800 [MHz] TClock 200 [MHz] DDR 750 [MHz] DRAM: 3.4 GiBYou can check the board info:
Marvell>> bdinfo arch_number = 0x00000000 boot_params = 0x00000100 DRAM bank = 0x00000000 -> start = 0x00000000 -> size = 0x04000000 DRAM bank = 0x00000001 -> start = 0x05400000 -> size = 0x7AC00000 DRAM bank = 0x00000002 -> start = 0x80000000 -> size = 0x40000000 DRAM bank = 0x00000003 -> start = 0xC0000000 -> size = 0x10000000 DRAM bank = 0x00000004 -> start = 0xE0000000 -> size = 0x08000000 baudrate = 115200 bps TLB addr = 0x7FFF0000 relocaddr = 0x7FF36000 reloc off = 0x7FF36000 irq_sp = 0x7F623350 sp start = 0x7F623350 Early malloc usage: 228 / 2000 fdt_blob = 000000007f623360And adding up those sizes gives 0xD6C00000 = 3602907136 = 3.6GB = 3.35GiB
