+ To connect RTT block, you can configure RTT viewer configuration based on where RTT block is in a map file.
+ To place RTT block specific area, you can add the following line to `fsp.ld`:
```
.bss :
{
. = ALIGN(4);
__bss_start__ = .;
*(.bss*)
*(COMMON)
KEEP(*(.rtt_block)) /* <-- for SEGGER_RTT control block */
. = ALIGN(4);
__bss_end__ = .;
} > RAM
```
Also, adding the following line to `SEGGER_RTT.c`:
```
SEGGER_RTT_CB _SEGGER_RTT __attribute__((section(".rtt_block")));
```
As the result, you can find the following similar line in the map file.
e.g.
[test_RA6M4.map]
```
COMMON 0x200232a8 0xa8 ./src/SEGGER_RTT/SEGGER_RTT.o\
