TMS320F28377D: No response to IPC interrupt using BIOS system

Part Number: TMS320F28377D
Other Parts Discussed in Thread: SYSBIOS, C2000WARE

My customer is developing F28377D, now they meet issues on IPC usage using BIOS system.

The basic operating system is below:

CCS Ver.：9.3.0

Compiler Version：TI v18.12.4.LTS

BIOS Ver.：6.76.03.01

There is a large amount of data exchange between CPU1 and CPU2, which is currently controlled by the timer + IPCFlag method. I want to use timer + IPC interrupt to control. Refer to the dual-core IPC interrupt routine given by TI, adding IPC interrupt in the SYSBIOS version, but there is no response.

TI reference code is：

C:\ti\c2000\C2000Ware_3_02_00_00\device_support\f2837xd\examples\dual

cpu01_to_cpu02_ipcdrivers and cpu02_to_cpu01_ipcdrivers

Customer code can provide in email if needed.

BTW, Could you kindly give customer some check lists to debug?

Hi Emma,

I'd recommend the customer take a SYS/BIOS example and verify it works. Then add the IPC interrupt via the Hwi module to that example.

i Todd,

Customer did use HWI module to add IPC.

does there anything wrong?

var hwi5Params0 = new Hwi.Params();
hwi5Params0.instance.name = "hwi132";
hwi5Params0.enableInt = false;

Program.global.hwi132 = Hwi.create(132, "&CPU02toCPU01IPC0IntHandler", hwi5Params0);

also attached the cfg file.

2350.app.cfg

Hi Emma,

They need to enable the Hwi.

Emma,

Can they attach their project (or a small sample project) that shows the issue?

Hi Emma,

This is not an TI-RTOS issue. App2 is never setting the register to cause the ISR on core1. When I added a “IpcRegs.IPCSET.bit.IPC0 = 1;” on app2 (e.g. at the end of the task), the IPC ISR on core 1 ran.
