Other Parts Discussed in Thread: HALCOGEN
Hi @ all,
I am using the TMS570LC43 HDK together with CCS Version: 6.0.1.00040 and HALCoGen 04.01.00.
To get familar with the concept of different load and run addresses I implemented an small sample project that uses copy tables in conjunction
with the copy_in RTS-function in preparation for an XCPoE-based flash tool (automotive). Up to the point where the program should do the execution from RAM
everything works fine: correct entries in map-file, RAM contains same code as ROM after using copy_in.
Then when calling the function by function name the program runs into prefetchentry. Following the call sequence in disassembly window, the trampoline is called and jumps to prefetchEntry.
Here the basic snippets of my test project:

Can anybody give me a hint, what is wrong with the implementation or my understanding of the concept itself?
Thank you in advance!
