Hi Tao

You can first increase verbosity modifying the update_prebuilt script available in the device/stm/stm32mp1/scripts/prebuilt

It's just a series of build commands.

add "--verbose 2" option to all failed build commands.

By default, the programmer update is not necessary (you can also bypass, commenting in the script the commands associated).

For the OP-TEE OS issue, you can also build it separately using directly the command:

build_tee --verbose 2

​It looks like didn't work, no valid log output.

Sorry, I made a mistake: it's the option: --verbose=2 you have to use as it's mentioned in the script helper.

Hi Nicolas

Looks like crypto lob can't be found, how do I add this library?

Error:No module named 'Crypto'

There is a missing python package in your environnement.

Can you cross-check your installation vs the Prerequisites wiki page ? https://wiki.st.com/stm32mpu-ecosystem-v2/wiki/PC_prerequisites#Installing_extra_packages_for_AndroidTM
