Did you try

what does your linker script look like? In what section is your code put by the linker?
- Altera_Forum
i can't see and edit the linker file,the file is created by the IDE automatically,can you tell me how to see and edit the linker file? thank you!

If you are using the IDE, it is in your system library > Debug > system_description > generated.x

From what I can read in the linker script, you don't have any section called onchip_memory. You have instruction_onchipmemory (address 0x08000000) and onchip_memory2_0 (address 0x04000000).
One of those should be your TCM memory. Use its name as section name, without the . in front, and see if it works.
