secure boot build code issue by using LSDK 20.04

[tzongruey]

Hi,

I try to build the LS1088 secure boot image by using LSDK 20.04.
It will occur an error when I build the optee_test application.
The following is the error of building the optee_test application.

I try to modify the file_to_c python file but it will occur other error as follows.

I also found that this issue didn't occur in the new version of LSDK.
It can build successfully in LSDK21.08 and LSDK20.12.
This issue occurs in LSDK 20.04.
The attached files is the build log I collected.
How can I fix this issue in LSDK 20.04?

Thanks

I have verified building optee_test in flexbuild_lsdk2004_update_290520 on my host PC, I didn't find any problem to run the following commands.

$ flex-builder -c optee_os -a arm64

$ flex-builder -c optee_test -a arm64

Please refer to the following my host PC information.

yiping@flexbuild-790:~/flexbuild_lsdk2004_update_290520$ python --version
Python 2.7.17

Hi,

I have checked the environment information on my host PC.
I found that the issue is caused by the python version and python crypto module.
I change the python version from 3.6.9 to 2.7.17 and install pycryptodome.
It can build successfully in my environment.
Thanks for your help.

Thanks
