EVMK2H: IPC failed to start

Chanh Nguyen64

Part Number: EVMK2H

Hi all,

I have create a simple IPC program for communication between ARM and DSP. The IPC_start function always return Ipc_E_NOTREADY (-11). Could you please help to check on what is the issue? Attached is my program. I use RTOS for bot ARM and DSP.

Another issue (I do not know if related to this error), everytime I run the ARM core, there is a error below:

arm_A15_0: Unhandled ADP_Stopped exception 0x800331B8

The gel file also attached.

Workspace_IPC.zip

8081.xtcievmk2x_arm.gel

PS. I want to try the ipc example TCI6636_bios_elf\ex02_messageq but failed to run, so I create a more simple program for easilier troubleshoot.

Hello,

Please check ROV in CCS (Tools > ROV Classic) for any errors on both the ARM and DSP side after the code has run. You can do BIOS > Scan for Errors, as well as look at the IPC module.

There was an issue in the past where the ARM application was running out of stack and resulted in the error you are seeing so please check ROV for any stack overflow as well.

Also, regarding the messageQ example failing to run - have you made any changes to the example?

Hi Sahin,

I have scan the BIOS but no error found: "All ROV views have been run and no errors were encountered. In BIOS, this includes a check of the System stack usage and all Task stacks."

Attached is the screenshot of ROV on the IPC

I did not see anything wrong.

Thanks.

For the messageQ example failing to run, I just rebuild the example without any change. By the way, I already ask about this problem at:

https://e2e.ti.com/support/processors/f/791/t/882636

But I have not get the solution yet.

Thanks.

Hello,

Can you try setting BIOS.smpEnabled = false?

Hi Sahin,

Yes after I try setting BIOS.smpEnabled = false and change all the SMP module to XDC Runtime module, I am able to run the example from ex02_messageq.

So I think I will based to that to modify for my test.

Thanks.
