Hi,

I tried to link applications to non-standard locations, got error messages like:

how can I avoid it?

Thanks

In addition, the new version of GRLIB relies on NCC that require ‘_Zicsr_Zifencei’ extension support (software/noelv/systest/Makefile, RISCV_ARCH ?= rv$(XLEN)ima_zicsr_zifencei), currently I have temporarily disabled this extension. Do you have any plans to release a new version of NCC ?

Sorry to go back to this issue.

To support a load address of 0x80000000 on a 64-bit target, I need to rebuild the NCC that defaults to medany cmodel, is there any relevant guidance or script available ?

I am trying to port the bcc-2.3.0/ubuild.sh script.

The issue was solved by using the rebuilding version of NCC.
