where to set supported_xlen to 64

[hyperion009]

XLEN's default setting is 64. Where to set supported_xlen to 64? I got thi following issue:
ERROR | riscv32-unknown-elf-objdump: executable not found. Please check environment setup

I am intended to run test with 64 and only settup the riscv64-unknown-elf-xxx

You will have to specify the correct isa of your implementation in your isa configuration yaml. Incase you have only implemented the riscv64-* toolchain but you are testing for a RV32 implementation, you can just rename the tool binary appropriately or change the plugin to use the correct toolchain.

thank pawks for your response.
yes, my implementation is only 64. Could you help me point to where to use the correct toolchain by plugin?
thanks in advance.

Make sure RV64 toolchain and riscv_sim_RV64 are in PATH. Edit spike_isa.yaml under spike dir, change supported_xlen to [64], change field rv32 to rv64, then run the test. Hope help.
