gdb and daig_printf()

Altera_Forum · ‎10-03-2005

Is it possible to use jtag_uart with gdb, i.e. I want to use gdb via nios2-gdb-server --tcpport=2343 and still use diag_printf over the same jtag port. It looks like it should be possible in the config by setting CYGSEM_HAL_DIAG_MANGLER to gdb and CYGDBG_HAL_DIAG_TO_DEBUG_CHAN to True.

Whatever combination I use fails to work, I might be something to do with my app not starting when I use diag_printf() until I run nios2-terminal

Help!

Thanks Robert.

Hello,

simply start two shells, on one start nios2-gdb-server and on the other start nios2-terminal. The jtag_uart is indeed blocking: if you don't have the nios2-terminal running, the application blocks in the diag_printf call.

Regards,

Andreas.

Great, this worked, I was trying to get the output into insight, but this will do just fine.

I disabled mangling, for what it's worth.
