l want to set the SRAM to get what l needed setting on s32k144

[jinshuaixu]

now ,l want set customSection from 0x1fffc000 t0 0x1fffdfff  and customSection1 from 20000000 to 20001fff. who can tell me how to change s32k144_link.ld ? thank you . 

/* SRAM_L */
m_data (RW) : ORIGIN = 0x1FFF8000, LENGTH = 0X00004000 /*16K*/
/* SRAM_U */
m_data_2 (RW) : ORIGIN = 0x1FFFC000, LENGTH = 0x0000b000/* 16k+28k=44k=b000 */

/* Custom Section Block that can be used to place data at absolute address. */
/* Use __attribute__((section (".customSection"))) to place data here. */
.customSectionBlock ORIGIN(m_data_2) :
{
/* l want to set customSection section 8k size from 0x1fffc000 to 0x1fffdfff */??????????????????????????????
KEEP(*(.customSection)) /* Keep section even if not referenced. */
/* l want to set customSection1 section 8k size from 0x2000 0000 to 0x20001fff */????????????????????????
KEEP(*(.customSection1)) /* Keep section even if not referenced. */
} > m_data_2

l have solve this problem,below is the way:

       .SRAM1 ORIGIN(m_data_2) :
{
KEEP(*(.SRAM1)) /* Keep section even if not referenced. */
} > m_data_2
.SRAM2 :AT(0X1FFFE000)
{
KEEP(*(.SRAM2))
}> m_data_2
.CUSTOM_DATA_RAM :AT(0X20000000)
{
KEEP(*(.CUSTOM_DATA_RAM))
}> m_data_2
