Hi.
Around 300MB is missing when I'm starting my C2.
I'm using Odroid C2 as headless device - we I'm starting it around 300MB is taken away from RAM (1719MB is available) Can we arrange other memory split/kernel config for headless option (is sad that 300MB is gone).
Regards Chris
Odroid C2 - 300MB gone (RAM)

Hi filemoon,

But you can give it a try to edit your C2 boot.ini like the one in C1 :

DietPi for Odroid C2 is currently based on Meveric's excellent Debian Jessie (arm64) image and he said no (at the moment).Can we arrange other memory split/kernel config for headless option (is sad that 300MB is gone).

Code: Select all

# 0 = disabled
# 1 = enabled
setenv vpu "0"
# Disable HDMI Output (Again, saves ram!)
# 0 = disabled
# 1 = enabled
setenv hdmioutput "0"

Looks like the GPU/VPU is using 256MB memory split. Actual RAM used after boot is 100MB.filemoon wrote:Hi.

As there are no options available in boot.ini to change this (like the C1), you'd probably need to compile a kernel with GPU/VPU features disabled to try and recover the memory.
As C2 kernel devolpment is nearly daily, it wouldnt be feasible for us to maintain a custom kernel at this time.
