Rock64 u-boot for eMMC Build Error

[mexicanflyer]

I have a Rock64 4GB board which I would like to turn into a FreedomBox server.

Since the Rock64 boards are no longer sold with SPI flash, I am trying
to build U-Boot to flash onto the eMMC module. I am following the instructions
for building here:

https://u-boot.readthedocs.io/en/latest/...kchip.html

However, when I get to here:

Code:

make CROSS_COMPILE=aarch64-linux-gnu-

I get this error:

Code:

ModuleNotFoundError: No module named 'distutils.core'
make[2]: *** [scripts/dtc/pylibfdt/Makefile:30: rebuild] Error 1
make[1]: *** [scripts/Makefile.build:398: scripts/dtc/pylibfdt] Error 2
make: *** [Makefile:2047: scripts_dtc] Error 2

Some investigation tells me pylibfdt is not yet compatible with python3, and it will
be a while before the developers will be able to solve the problem, as it causes many other issues.
I installed python2, but I get this error:

Code:

scripts/dtc/pylibfdt/libfdt_wrap.c:154:11: fatal error: Python.h: No such file or directory
  154 | # include <Python.h>
      |           ^~~~~~~~~~
compilation terminated.
error: command '/usr/bin/cc' failed with exit code 1
make[2]: *** [scripts/dtc/pylibfdt/Makefile:30: rebuild] Error 1
make[1]: *** [scripts/Makefile.build:398: scripts/dtc/pylibfdt] Error 2
make: *** [Makefile:2047: scripts_dtc] Error 2

What am I able to do in order to work around this issue?

For clarity, will the u-boot and FreedomBox installations exist on the same eMMC module in the end, or must I install one to an SD card and the other on the eMMC module?


Thank you for reading the post. I would appreciate any advice you have to offer.
