Target configuration
Global target configuration variables
There are some aspects of target configuration that are controlled through global GDB convenience variables instead of a providing variants of the target connection commands.
To change the default behavior controlled by these convenience variables, they need to be set before connecting to a target.
The board or SoC they control is encoded into the convenience variable name.

If this is non-zero, the LMI SYS and LMI VID configuration registers for the STb7109 are relocated to their Area 6 addresses (see STx7109
Datasheet (7976546)).
If this is non-zero, the LMI configuration registers for the STi5202 are relocated to their Area 6 addresses
(see STx5202 Datasheet (8040779)).
Reset delay interval in milliseconds. Similar to the resetdelay
STMC1 configuration command (see
Table 7: Common STMC configuration commands on page 15
).
If this is non-zero, the size of the memory attached to LMI SYS for an STb7109-Ref board (MB442) is
128 Mbytes.
If this is zero, the size of the memory attached to LMI
SYS for an STb7109-Ref board (MB442) is
64 Mbytes.
