The xcl file of MSP430FR6972 cannot change the heap DATA16_HEAP starting address [Copy link]

Hello everyone:

This is the changed xcl file for msp430fr6972:

//-----------------------------
// Read/write data in FRAM
//
-Z(DATA)MYSEGMENT=4400-47FF
- Z(DATA)DATA16_HEAP+_DATA16_HEAP_SIZE
-Z(CONST)DATA16_P,DATA20_P=4800-FF7F
//-Z(DATA)DATA16_HEAP+_DATA16_HEAP_SIZE
//-Z(DATA)DATA20_HEAP+_DATA20_HEAP_SIZE

The compiled mapping file .map section:

DATA16_AN 4400 - 4401 2 rel 0
MYSEGMENT 4402 - 4479 78 rel 1
DATA16_HEAP 4800 - 489F A0 rel 1
DATA16_C 48A0 - 5B4B 12AC rel 1

Why does the starting address of DATA16_HEAP always start from 4800? I have also tried to put the -Z(DATA)DATA16_HEAP+_DATA16_HEAP_SIZE instruction in the RAM area.

But the starting address still starts from 4800, as if the -Z command does not work. Please give me some advice, thank you!!!
