Following the steps outlined here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/latest/exports/docs/linux/Overview_Building_the_SDK.html
The build ultimately fails because it cannot clone the submodules in .../tisdk/build/arago-tmp-default-glibc/work/aarch64-oe-linux/powervr-graphics/5.10-r0/git/
If I navigate to that directory and go a 'git submodule init' and 'git submodule update' manually and then re-run the bitbake command then all task complete successfully.
I have the proxies configured correctly to clone everything else in the build process successfully.
Error log here:
