TMS320F28379D: Increase memory (heap size)

Hi -- what is the maximum limit for heap size for F28379D (TMDSCNCD28379D)? And how to increase it from the existing limit?

I Matlab Simulink: Model Configuration Parameters -> Code Generation -> Build Process -> Build Configuration -> Specify the maximum number I can enter is 0x1000 for both loading and External mode to work OK.

-z -I$(TI_LIB) --stack_size=$(STACK_SIZE) --warn_sections --heap_size=0x1000 --reread_libs --rom_model -m"$(PRODUCT_NAME).map"

For 0x1100

-z -I$(TI_LIB) --stack_size=$(STACK_SIZE) --warn_sections --heap_size=0x1100 --reread_libs --rom_model -m"$(PRODUCT_NAME).map"

loading the application code (Downloading program to the target hardware... & Build process completed successfully) is OK, but if I try to run in External mode, I get the error message:

The error message says something about the c28377D.cmd and that the program will not fit into available memory. Is it a because I use c28379D.cmd file for 28379D? In C:/ProgramData/MATLAB/SupportPackages/R2018a/toolbox/target/supportpackages/tic2000/src/ there is no corresponding linker command file.

In this thread I read max. memory for one CPU is 512KB; how this translates to heap size?

In other threads for 28335 they suggest

text : >> RAML1 | RAML2,  PAGE = 0

but in c28377D.cmd RAML1 and RAML2 are not defined as variables; not sure if the steps (solutions) for F28335 apply to F28397D.
