TMS320F28388D: CPU1 waitForFlag after implemented mqtt

Hi, 

Can you clarify/elborate on your question? Is the IPC communication not working or the MQTT client does not connect?

Best Regards

Siddharth

Hi,

thanks for your reply.

IPC work without mqtt connect. When launch my application with mqtt connect Its dont work, is blocked in cpu and wait change the flag.

Hi, 

Can you proivde some details about your application? I am not so familiar with MQTT.

Are you trying to get data from MQTT client runnig on CM core and send it to CPU1 using IPC?

Best Regards

Siddharth

Hi,

in my application use cpu1 and cm, befor implemented mqtt part all its work (tcp, adc. Uart). 

 I have already implemented ipc_sync into main cpu1 and cm

I have imported mqtt.c (C2000Ware_4_01_00_00\libraries\communications\Ethernet\third_party\lwip\lwip-2.1.2\src\apps\mqtt\mqtt.c)  and follow guide line for implementation mqtt_client  https://www.nongnu.org/lwip/2_0_x/group__mqtt.html .

After this, when my application restart, is blocked in cpu1 and wait the flag

but if delete the connect fuction Its work

Hi,

Based on your response, the MQQT client seems to be working fine , there is an issue with the IPC.

Please refer the following article , section 4.2. IPC Flags and Command registers to see if the IPC communication is setup properly

Hi,

I dont know if the mqtt client working fine, because when implemented mqtt part cm dont start. IPC without mqtt part working fine.

Cm dont start and c28x1 dont receive ipc sync but I dont why the cm is blocked if implemented mqtt connect

Hi, 

Can you get the MQTT client to work on the CM side first before trying to use the IPC?  

It will help to isolate the problem to be either on the CM side or IPC.

Best Regards

Siddharth

Ih,

I tried but cm dont start.

Hi, 

How are you loading the application to cm core? What are the steps that you are carrying out to run from CM core?

Best Regards

Siddharth

Hi,

I load cm with ccs ide below the steps

 CM_init();

Flash_initModule(FLASH0CTRL_BASE, FLASH0ECC_BASE, 2);

SYSTICK_setPeriod(SYSTICK_PERIOD);
SYSTICK_enableCounter();
SYSTICK_registerInterruptHandler(SysTickIntHandler);
SYSTICK_enableInterrupt();

Interrupt_enableInProcessor();

 TRY(util_init());

then enable TCP_IP and MQTT.

Same problem if delete the mqtt_connect cm start if mqtt_connect enable dont start.

it would seem the problem is mqtt, do you have any suggestions?

Best Regards

Hi,  

I am not familiar with Mqtt, will check and get back to you.

Best Regards

Siddharth 

thank you, Let me know what you think.

Best Regards

Hi, 

Okay, will update you in a couple of days

Best Regards

Siddharth

Hi, 

ok , wait you.

Best Regards

Hi,

I realized this error when it doesn’t start cm 

Cortex_M4_0: AutoRun: Target not run as breakpoint could not be set: _JobHardwareBreakpoint::ARM_DEBUG_V7M_fpb_add_breakpoint: FPB : All resources are in use.[25062]

Best Regards

Hi, 

This error indicates that it is unable to add any more breakpoints since  it used up all the existing breakpoint resources. You can have a max of 2 hardware breakpoints while debugging. You can disable all breakpoints and relaunch the debugger to check if it works. 

Is the code not even executing till main on the cm side? 

Best Regards

Siddharth

Hi,

I don't have any breakpoint . Can you see thr screen. The code does not run.

I followed this advice  https://dev.ti.com/tirex/explore/node?node=AFxRAHEqhlcitK5yopkNoA__FUz-xrs__LATEST

But the problem remained

Best Regards

I have this problen only whit mqtt_connect

Hi, 

Are you able to run the code till main() when you add the mqtt_connect?

Best Regards

Siddharth

Hi,

It would appear not, main dont start

Best Regards

Hi, 

It indicates something is incorrect during the initialization stage itself. 

Can you single step through the code after loading to CM? Or is it possible for you to share your code so that I can take a look.

Best Regards

Siddharth

Hi,

if you want send you my code in private message.

Best Regards

Hi, 

Yes, you can share it via private message.

Best Regards

Siddharth

Hi, any news?

best regards

Hi, 

I tried it out . I loaded CPU1 and then CM. 

execute CM core first and then CPU1 code.  Looks like the CM is waiting for Ack 

Best Regards

Siddharth
