Hi

Which part are you using? Which compiler are you using?

The general answer would be:

If the address space is continuous you can create just one memory section instead of separate blocks

e.g. default MPC5744P linker script file for GCC from project generated by S32DS:

MEMORY
{
flash_rchw : org = 0x00FA0000, len = 0x4
 cpu0_reset_vec : org = 0x00FA0004, len = 0x4
 
 m_text : org = 0x1000000, len = 2048K 
 m_data : org = 0x40000000, len = 384K
 
 local_dmem : org = 0x50800000, len = 64K 
}‍‍‍‍‍‍‍‍‍‍

in the linker script above there is a gap 0x00FA0008..0x00FFFFFF

to avoid the gap you can adjust the m_text block:

MEMORY
{
flash_rchw : org = 0x00FA0000, len = 0x4
 cpu0_reset_vec : org = 0x00FA0004, len = 0x4
m_text : org = 0x00FA0008, len = 2432K - 8 ‍‍‍‍‍‍‍‍‍‍

Hope it helps.
