Hello
I just tried to debug a riscv test program running in qemu.
However, gdb could not establish a connection to qemu and produced the
following error:
/tmp/rtems/riscv❯ riscv-rtems6-gdb ticker.exe
GNU gdb (GDB) 10.1.90.20210125-git
[..]
For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from
/tools/modulesystem/tools/rtems/rtems6/install/bsps/riscv-rtems6/grv32imafdc-smp/testsuites/samples/ticker.exe...
(gdb) target remote :1234
Remote debugging using :1234
bfd requires flen 8, but target has flen 4
The tools and rtems are built from master a couple of days ago.
I used the following command line for qemu (v. 4.2.0):
qemu-system-riscv32 -nographic -machine virt -m 2G -nographic -net none -serial
mon:stdio -bios /tmp/riscv/ticker.exe -s -S
Does anyone have a hint if the problem is with qemu, gdb or rtems?
Without gdb the program runs normally in qemu.
Best regards,
