Hello,
We want to use gdb server to debug application on i.MX6ULL. The OS of i.MX6ULL is Linux, and to debug an user application with cross compiled gdb server.
We found the application can be stopped in breakpoint, but it can not be stopped on:
* step;
* hardware point;
And the watchpoint is also invalid.
Should we do some setting in i.MX6ULL? Thanks.
Please refer to the following Application Note document:

Best Regards,
Artur

BTW, GDB is not hardware debugger like trace32 of Lauterbach and it can set hardware break point.
