Memory mapping for dual core application

[techexplorer_139]

Hi,

I am using imxRT-1176 EVKB and working dual core application. CM 7 is my primary core and CM4 is my secondary (slave) core. In my application CM7 and CM4 will have same code with shared memory. CM7 code is working fine but as i use the same code in CM4 the memory overflows. Help me in memory management so both core can work properly.

CM7 Memory mapping:

Hi @techexplorer_139 ,

Thank you so much for your interest in our products and for using our community.

1: Did you use MIMXRT1170-EVKB development board or your customed board?

2: Which SDK demo do your use.

I suggest you can refer to SDK demo "evkbmimxrt1170_hello_world_secondary_core_boot_primary_core_cm7" and "evkbmimxrt1170_hello_world_secondary_core_boot_secondary_core_cm4"

For CM7 project:

For CM4 project:

Please double check CORE1_BOOT_ADDRESS setting in " the evkbmimxrt1170_hello_world_secondary_core_boot_primary_core_cm7"

@mayliu1 I need more space to store my source code which is approx 4MB. and if i change the memory addresses and MCU linker then it doesnt work properly.
