I think you  might have missed a step here -> by default when you clone,
  you get to the master branch which is not aligned with the OE
  configuration you picked. OE recipes is a bit smarter, and picks a specific
  commit in a release and builds with it.

Since I am familiar with the convention, the branch you are looking for
is ti-u-boot-2020.01   So: git checkout ti-u-boot-2020.01   to flip over
to the branch that coresdk-07.03.00.05 -> you can even pick the exact
tag corresponding to the release if you like.

Hmm.. personally I did'nt know you could mix defconfig and all step  in
one shot.. but hey, seems to work for me:
$ git branch -v
  master            a15fa1ba67d7 Merge tag 'dm-pull-21jul21' of https://gitlab.denx.de/u-boot/custodians/u-boot-dm
* ti-u-boot-2020.01 e995ed0ec11b configs: am64x_sk: Drop unused defconfigs

$ make -j`nproc` CROSS_COMPILE=arm-linux-gnueabihf- O=CSCM_build am335x_evm_mini_defconfig all

[...]
  COPY    spl/u-boot-spl.bin
  MKIMAGE MLO
  MKIMAGE MLO.byteswap
  CFGCHK  u-boot.cfg

Now, that said, since there is a bit of a mix of TI conventions involved, i would
suggest asking for help in https://e2e.ti.com/
