JetPack 3.2 setting maximum memory

On JetPack 3.2 on my Jetson TX2, I am attempting to emulate having 4 GB of memory. I edited /boot/extlinux/extlinux.confon the line starting APPEND ${cbootargs} ... to add mem=4G, but it has no effect. What am I missing?

Could you flash by 4G parameter.

sudo ./ -r jetson-tx2-as-4GB mmcblk0p1

I will do my best to try this in the time we have available. Our flashing process is a bit involved. If there’s a way to add a kernel parameter and reboot, that would be awesome.


you can either update the memory info
by passing a DRAM mem cfg file with size as 4GB. look for

SDRAM.McEmemCfg = 0x00002000; <== 8gb

this info is then fed to memory node in kernel dts.
so kernel command line will not work anymore

Thank you! – Where would I find this setting? I could not find anything matching in /boot. Is this in the flashing process?

It’s generate by the sdkmaager like the cfg file should be in below directory.
