Hello,

We have the following setup for our project:

PC running ARM-GDB <---> Segger JLink GDB server <---JTAG--> RM48.

We would like to use printf statements and get the output on our armgdb, how is this possible?

I am currently using the Hello world project from this post :

Which adds sys_memory. It seems like the printf is writing to this memory but how can I obtain this?

Regards,

Karel

Karel,

What you are looking for is semihosting support for your program in GDB, which is not something we (TI) support directly.

You will have to use the rdimon library (instead of the more common nosys) and perform a few steps to properly enable this in your project and use this on GDB.

Some details are shown in the reference below:
bgamari.github.io/.../2014-10-31-semihosting.html

I suspect you also went through the details shown at Segger's documentation, but I copy it here for reference:

Hope this helps,
Rafael
