I want to run simple hello.c example So I compiled as following:
riscv64-unknown-elf-gcc hello.c -L linker.lds -o hello.elf
where linker.lds is :


  // I changed this to the DRAM start addr (0x80000000)
  ROM_BASE = 0x80000000; /* ... but actually position independent */

  . = ROM_BASE;

  .text.init : { *(.text.init) }

  .text : ALIGN(0x100) {
  _TEXT_START_ = .;
  _TEXT_END_ = .;

  .data : ALIGN(0x100) {
  _DATA_START_ = .;
  _DATA_END_ = .;

  PROVIDE(_data = ADDR(.data));
  PROVIDE(_data_lma = LOADADDR(.data));
  PROVIDE(_edata = .);

  .bss : ALIGN(0x100) {
  _BSS_START_ = .;
  _BSS_END_ = .;

  .rodata : ALIGN(0x100) {
  _RODATA_END_ = .;

and the compilation was successful. Then, I followed the instructions in GITHUB  connected with success to JTAG. the problem that I cannot run the the hello.elf I can only see the disassemble which looks correct. check what I tried:

~/Desktop/ariane_test/hello$ riscv64-unknown-elf-gdb hello.elf

You can't do that when your target is `exec'
(gdb) run
Don't know how to run.  Try "help target".
Could you please help me, I want to see 'Hello Ariane' printed on the console
Thank you
Did you try to use the default linker script?

yes indeed I used /fpga/ariane.cfg script to connect to the JTAG
That is not the linker script. It is a OpenOCD script.
