"heaplow out of memory" error booting

[cecio]

Hey.

I need some guidance for this issue:

I cloned locally the repository, then set up the compile environment with:

• aarch64 toolchain version 10.3-2021.07
• Circle version 44.3
• I copied the files in Source/Firmware/Circle in the proper places
• I compiled Sidekick with make kernel=menu RASPPI=3 AARCH=64 without changing anything else
  I get a kernel8.img which I placed (properly renamed) on the SD card.

After that if I try to boot the Sidekick, I see this error as first and only message (I attached a monitor to HDMI):

heaplow out of memory

and then the boot process stops. If I place the previous image (coming from the zip file of latest release), everything works again. So, probably there is something wrong in my image, but I did not change anything in the code, just compiled. The images size is exactly the same of the working one. The sha256 of the two files are different, my new image and the old one differs of few bytes (7 in total).
I'm sure I'm doing something wrong, but I'm not getting what.

Thanks for the help!
