Add the routines available in mem_safe.h to the system. This is added
|
|
|
|
|
as a kconfig option instead of simply linking against the library
|
|

because some implementations might require initialization.

Other regions can be added as needed by using the

sys_mem_safe_region_add() API. The number of regions that can be added

is controlled via the MEM_SAFE_NUM_REGIONS kconfig option.

The functions available in mem_safe.h check if memory is within
|
|
|
|
|
read-only or read-write regions before accessing it instead of crashing.
|
|
|
|
|
The kernel image is added as a valid region automatically, but other
|
|
|
|
|
regions can be added if the application makes access to additional
|
|
|
|
|
memory outside of the image's boundaries.

debug: add target GDB server
The GDB server implements a set of GDB commands, such as read/write
memory, read/write registers, connect/detach, breakpoints, single-step,
continue. It is not OS-aware, and thus provides a 'system-level'
debugging environment, where the system stops when debugging (such as
handling a breakpoint or single-stepping).
It currently only works over a serial line, taking over the
uart_console. If target code prints over the console, the GDB server
intecepts them and does not send the characters directly over the serial
line, but rather wraps them in a packet handled by the GDB client.
