How to get data from a fixed address after startup？

[DDing.1]

I want to take out the data I need from a certain address after startup,

I created an array inside tf-a ( char array [0x200] = {}) , and I read the address of the array printf("%p", (void*) &array), which seems to never be repeated after many compilations The address will be changed, but the question is how do I get the data of this array address after startup?

I tried to change the address in the conf.mk file to the array address. Modify the get_tpm_phys_params() function in the tpm.c file in optee_os to get the character address, and finally get it with the code of xtest1024, but it seems to be unsuccessful. Could you please tell me what is wrong or is there any way to get the data in my address?

Create a special linker section for your data.

I created an array inside tf-a ???

Simply read data from memory is

and ofcourse datatype selection.
