I haven't yet. The build script for tizen on yocto is based on the x86-64 configuration.
So some effort is needed to make the build work for x86-32 machine.

Anyway, have you tried to use x86-32 rather than x86-64? Using x86-64 in 64MB system seems inappropriate.

Reason: the ISA itself is different.
Even between x86-32 vs x86-64, usually, people report that the size (both the binary size and runtime memory footprint) increases around 20%. Besides, we have been using THUMB for ARM (armv7 / aarch32) to reduce the size and aarch64 does not allow to use THUMB, which in turn, increases the size gap between aarch32 vs aarch64 further than x86-32 vs x86-64.
Thus, it's trivial to expect that x86-64 (or even aarch64) will have much larger size than aarch32/arm7 binaries. The question for you will be how to reduce the size to fit in 64MB :)
Cheers,
MyungJoo.

Thanks for your reply.
As you expected, the image size of x86-64 is much larger then that of arm. Also, the RSS and PSS of the
processes on x86-64 is larger than that of arm, even though the gap betweenthe same processes differs
depending on the process. I also suspected like you, when I saw that the boot with the x86-64 image failed.
But I couldn't find the reason from where this difference comes. From where, could you expect like you said?

Have you compared the image size (and runtime memory footprint as well) of ARM binaries and x86-64 binaries? I expect that the latter is much larger.

Title : [Dev] How should I do to make it boot on the low-end machine with 64MB main memory?
Hi,
I'm trying to run Tizen Linux in the machine with Intel ivy bridge, and 64MB main memory. I followed the instructions in https://wiki.tizen.org/wiki/Tizen_on_yocto. But it failed to boot becuase out of memory. The image which is made after the instructions includes weston for GUI, and systemd for init. It seems that they use too many memory to run on the machine with 64MB. I saw that the image core-image-sato, which includes X and matchbox for GUI and sysvinit for init, is able to run on QEMU-ARM with 64MB, even though it failed to do on QEMU-x86_64. But especially I am interested to boot the image with weston. I wonder what I am missing. Is there someone who succeeded to boot the Tizen Linux or a Linux with weston in this kind of environments, or can give me some advice?
Thanks.
Best regards,
Hyungwon Hwang
