TMS320F28379D: Starting cpu2 program in RAM

Piotr Romaniuk

Part Number: TMS320F28379D

Tool/software:

Hi,

Due to problems with other TI tools (20% of errors in mass production) I write a bootloader that runs in RAM and writes program to flash memory.
I already developed working solution for cpu1 and now I stuck on cpu2.

I downloaded a program for cpu2 into RAMGS4.
How can I make cpu2 to execute that code?
Cpu2 should be in WaitBoot.

I need to do this from cpu1.

My mistake.
I used incorrect register for sending jump address (IPCRECVADDR).
It should be IPCSENDADDR on cpu1 site.

IpcRegs.IPCSENDADDR = 0x10000; // jump address
IpcRegs.IPCSENDCOM  = IPC_BRANCH;
IpcRegs.IPCSET.all = (IPC_FLAG0 | IPC_FLAG31);

Hi Piotr,

Thanks for letting us know that you were able to get this resolved. In the future, I would recommend you check out our c2000 Academy training on the IPC module. https://dev.ti.com/tirex/explore/node?node=A__AEIJm0rwIeU.2P1OBWwlaA__C28X-ACADEMY__1sbHxUB__LATEST

Thank you Ozino for pointing me out that Academy.

Because I had linux kernel experience, I used to source code browsing and analysis.
Hence the examples in C2000-Ware and the source code of the BootROM are very valuable for me.

For sure I will visit the Academy.
