Honored Contributor:mad: No one can answer this question?
Honored ContributorDid you try
.section onchipmemorythank you,i am glad to try it again
Honored Contributori tried in different way,but still can't seen the objectcode carried to the TCM,if anyone know how to do this with assembly instruction please tell me,thank you very much!
Honored ContributorI have delayed this issue two weeks, please help me, thank you!:mad:
Honored Contributorwhat does your linker script look like? In what section is your code put by the linker?
Honored Contributori 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!
Honored ContributorIf you are using the IDE, it is in your system library > Debug > system_description > generated.x
Honored ContributorTO_BE_DONE
Honored ContributorFrom 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.
