Hello, expert Firstly, thanks for your answer some time ago. That's useful to our project.We combined the Hafnium (run at S-EL2) and the optee (run at S-EL1), then modified the configuration to adapt to our own environment. Now we can start the os normally. Now we want to optimize a technical point, which is to load and run hafnium over 34G of free address space. This requires hafnium to support 64-bit load-address. I tried to modify the configuration in BUILD.gn as follows: origin_address = "0x880000000" And I encountered the build error: FAILED: secure_aem_v8a_fvp_clang/hafnium.elf ld.lld -pie --gc-sections --defsym=ORIGIN_ADDRESS=0x880000000 -O2 --icf=all --fatal-warnings --color-diagnostics -T /home/yuye/hafnium/Hafnium/build/image/image.ld -o secure_aem_v8a_fvp_clang/hafnium.elf --start-group @secure_aem_v8a_fvp_clang/hafnium.elf.rsp --end-group ld.lld: error: secure_aem_v8a_fvp_clang/obj/src/arch/aarch64/entry.entry.o:(.init.entry+0xC8): relocation R_AARCH64_ABS32 out of range: 36507222016 is not in [-2147483648, 4294967295]; references ORIGIN_ADDRESS >>> defined in -defsym:1 ninja: build stopped: subcommand failed.

Is there any solutions or supports for this issue currently in the community? Regards, Mei, Jianqiang.
Hi,
Sorry for the delay in replying to this query. After few trials I ended with this possible solution: https://review.trustedfirmware.org/c/hafnium/hafnium/+/18510
This should permit loading the Hafnium image to an address up to 48 bits (and by updating project/reference/BUILD.gn origin_address per your suggestion). It is possible to further extend beyond 48 bits (e.g. 52 bits which is the maximum permitted VA using FEAT_LPA2).
Let me know if this works for you, then I can proceed further with polishing this change.
Regards, Olivier.
