Hi,

I am trying to load a compiled ariane-sdk based vmlinux to a FPGA (ROM built with ariane.dts) via GDB. But the physical memory address on FPGA is 0x2_0000_0000. I wonder where & how do I change the Kernel start/boot address?? Many thanks in advance!

Thanks Moschn!

I am only using vmlinux, not bbl or bbl.bin. Can I still use "riscv64-unknown-elf-objcopy" command to change start address? Please advise.
