Different RAM values on V1.3b model

VisionFive 2 （English Forum)

Hi all.
Hello everyone.
I’m new here. I have starfive vision 2 model v1.3b version. RAM 8G.
My problem:
When I use the latest SDK image sdcard.img
…# free -h shows 7.7G - I think that’s ok.
but when i use the latest debian image
boot from u-boot
…# sysboot mmc 1:3 fat 0x043900000 /extlinux/extlinux.conf
the system will boot fine.
…# free -h shows 3.8G - that means half the value
The question is:
Is there any way to solve this problem?

Thank you
sajcho

Have a look at Device trees limit Linux to 4GB of RAM on 8GB devices · Issue #20 · starfive-tech/VisionFive2 · GitHub on How to fix this.

Hi andrew.
Thanks for the tip and solving my problem.
I did a dtb recompile and the system now shows 8G.

Best regards
