Hi,
when trying External mode in MATLAB Simulink for TMDSCNCD28379D for CPU2 (Boot from Flash), I am already running a different application on CPU1 (Boot from Flash), I am getting an error saying "program will not fit into available memory"
<Linking>

The main part says:
RAMLS_DATA size: 0x2000 unused: 0x0 max hole: 0x0
RAMD1 size: 0x800 unused: 0x0 max hole: 0x0
This reply advises going into the Linker file and adding more sections to the heap area.
When I go to the Linker file C:\ProgramData\MATLAB\SupportPackages\R2018a\toolbox\target\supportpackages\tic2000\src\c28377D.cmd
Q1. I do not see .sysmem, only .esysmem. Is this a problem?
.esysmem : > RAMLS_DATA, PAGE = 1
Q2. There is only #ifdef CPU1 for CPU1 and not CPU2. Is this a problem?
Q3. I do not see available memory to add as OR ("|") in the linker file, only RAMLS_DATA. Should I modify RAMLS_DATA? Full Linker file is sjown below

I asked a similar question several months ago as I was having the same error ("program will not fit into available memory") and I assumed increasing the heap size from the MATLAB Simulink will solve the problem. It did, temporarily, but now I am still having the same issue.
