TMDSEVM6678: Jump address

KSH

Part Number: TMDSEVM6678

Tool/software:

Hello, I am trying to load a binary file written in nor memory, upload it to RAM, and then run it. 
I confirmed writing to memory, but there is a problem moving to the written address and executing it.

When I check the PC register, it does not move to the desired address. Could you please tell me how?

This is what I tried.

 uint8_t* appBuffer = (uint8_t*)0x0C000000;

 void (*appEntry)() = (void (*)())appBuffer;
 
 appEntry();

Have you tried this?

In CCS 9.3, you can load the binary directly to the RAM and execute it.

Once you are sure that the binary is able to run, you can load into NOR flash , set the boot switch settings accordingly to load from NOR.

---

Please follow the steps given in this FAQ to load the binary from NOR.

Thank you for the reply. 
I created two apps for testing, let's call them A and B.
Reflecting your reply, I created app A as a binary file and wrote it to a different address in RAM.
I want to go to the address of app A's main function with app B. 
App B attempted to move to an address that was equal to the offset of the main function of the address where App A was written, but App A did not run.

As a first step, test with single app binary with CCS 9.3 loading into RAM.

For example, the following FAQ demonstrates how to run the binary with CCS by loading directly into RAM.
