Hi all,

I generate code for my program with IBM Rhapsody and then it is executed on the Application Kit TC2X7. However if I add some new functionalities in my code I have the following linker-related errors:

I suppose that the code size is incompatible with the actual memory map set by default (.map):


Memory Configuration

*default* 0x00000000 0xffffffff 0x00000047 0xffffffb8


How can I solve this? Is there any documentation about memory configuration or procedure to do that under this architecture?

Thanks in advance

Your program has exceeded the internal PMI_PSPR RAM size. You need to reduce your code size, or change the linker/locator from iRAM to iROM (Flash).
