Question: Why does my device show 4GB of RAM when I really have 8GB? #220

Hi there,

Not really a bug but I'm surprised to only see 4GB of RAM available: I have 8GB on the board. htop also only shows 4GB available. Is there a reason for this? I'm curious...

Mine also is 8GB but shows 4gb,

I see a dmesg line very early in the boot:

[    0.000000] Memory limited to 4096MB

@peterwilli Nice catch, there was a kernel parameter which limited the memory to 4096M in the boot script:

If you pull this commit, then "make cmd/odroid/common/install" once more to update it on your sd card, it should remove the limit.

Confirmed: that fixed it:

Thanks so much, I'll try right now and super cool that I found something again, and as always checking out what you changed! Edit: All good here now!

@peterwilli Yup, just a small mistake in the configs, easy to fix!

Glad it's working properly now 👍🏽
