Space related issue with colibri vf50 between v1.1A and v1.2A

Hello,

I have used Yocto to prepare image Colibri-VF_Console-Image 2.7b5 plus its corresponding default u-boot too.
I burned this image to both Colibri VF50 V1.1A and V1.2A 128MB modules.

When I am running command df -h the output is following…

v1.1A

Now if we look at the first line at ubi0:rootfs,
Why there is a difference in size v1.1A is showing 70.7 MB while v1.2A is showing 100MB. ?? In V1.1A my system creates error in application, due to less memory.

Is there anything that i am doing wrong while creating the setup because of which the memory is less in V1.1A.???
Is there any specific difference between both the versions of SOC module/ image (version relative to module) related to memory ??

Please I need help urgently on this matter.

Hi @ryan

Which changes have you done when you compiled the image? Are you sure you flashed the same image on both modules? Could you provide the output of uname -r on both modules?

Is there any specific difference between both the versions of SOC module/ image (version relative to module) related to memory ??

The changes from Version 1.1A to 1.2A are reported in the PCN.
