Few questions about HSE installation via MU interface

[info-wizzair-help]

Hi,NXP

I'm trying to install HSE via MU interface in my S32K344 development board.

After reading lots of docs and files, i still have some questions.

1. I want to put pink-image in sram. I tried to use ld file to put image in sram directly,but it seems to fail. (Use ld file to put image in flash is OK)
HSE_FLASH : ORIGIN = 0x00502000, LENGTH = 0x00030000

HSE_SRAM : ORIGIN = 0x20410000, LENGTH = 0x00030000
