Hi champs,
My customer used F2812 and CCS v3.3(CGT v3.07) for applications before, now he wants to migrate his project to F280037 and CCS v12(CGT v22.6.0.LTS), but he is facing one .ebss size problem.
There is one parameter.cpp in the project, but the size of paramter.obj is in a big different when using CCS v3.3 and CCS v12 to build this project, please refer to below .map file portions,
** .map file built by CCS v3.3(CGT v3.07).

Because CGT v22.6.0.LTS generates many strange, big size parameter.obj, we don't have enough RAM size to assign to .ebss sector. Please advise how should we debug this problem, thanks for your help.
