Hi I am getting program memory fit into available memory error for .kernelHEAP. I solved issue by changing below line.

.kernelHEAP : {} > RAM -----------> .kernelHEAP : {} > RAM | SDRAM   [ Also I do some changes on length and origin attributes in code in the part of Memory scope. ]

Is there an official solution or document that I can follow to approach differently to the issue? Also, I am curious how it can be optimized in professional level? Could you give a recommendation?

Thanks and Regards,
