S32K322 emios 0 ch 9 SAOC

[francescovico]

Hello ,

I need to configure EMIOS0 CH9 in SAOC mode.

I would like enable COUNTER BUS A using CH23 and use this in CH9.

Attached the emios ConfigTools.

In the main the code is:

/* Init EMIOS MCL for enable global counter bus */

Emios_Mcl_Ip_Init(0, &Emios_Mcl_Ip_0_Config);

/* Init EMIOS OCU */

Emios_Ocu_Ip_Init(&Emios_Ocu_Ip_0_ModuleCfgPB_BOARD_InitPeripherals);

/* Enable EMIOS OCU Channel notification */

Emios_Ocu_Ip_EnableNotification(0,9);

/* Start EMIOS OCU Channel */

Emios_Ocu_Ip_StartChannel(0,9);

The Ocu doesn't work and any notification are done.

PS: using CH1 (that have internal counter) it's work .

Regards.

Hi@francescovico

Could you please share the project so that i can help you to check it .

Or tell us the RTD version you're using, we can provide to you a simliar demo for your reference,.

Hello @Senlent ,

attached a simple project that increment two variable at each ISR of two SAOC.

The EMIOS0 CH1 increment counter EMIOS0_OcuCh_1_ISR_cnt

The EMIOS0 CH9 increment counter EMIOS0_OcuCh_9_ISR_cnt

How you can see the counter EMIOS0_OcuCh_9_ISR_cnt it's zero.

Regards, Francesco.

Hi@francescovico

I tested the code you provided and it seems to work fine.

Attached is a screenshot of my test.

PS:I don't have a S32K322, so I tested the routine on a S32K344, which should be exactly the same

[francescovico]

It's very strange.

It's correct that CNT23 of EMIOS0 it's ever 0 ?

 

It's possible to have the .elf file of my project compiled using  S32K322 ?

I would like flash this elf file to see if it work fine.

Regards, Francesco.

Hi@francescovico

No, CNT23 should work, it shouldn't be 0 all the time.

and i have attach the "TEST_S32K322_M7_0.elf" for your test.

As i said before, i test your code in S32K344,not S32K322, but i think the result should be same with S32K322.

Hello, with your .elf file on my micro S32K322, CNT23 it's ever 0.
S32K322 it's dual core, this could be the cause of my problem?

Hi@francescovico

It seems that there is a connection, otherwise I can't think of any other factors. It seems that eMios0-ch23 is not working.

Is it possible to download and run only "TEST_S32K322_M7_0.elf" only, without burning "TEST_S32K322_M7_1.elf",please have a try again.

Also, could you please change below setting and have a try again.

Hello,

now It's working fine!

To work fine, it's necessary remove flag below:

This is a Bug in RTD ?

Thank you a lot !

Hi@francescovico

This is not a bug, your program should run normally when not in debug mode.
But I am a little puzzled, because I checked this option and it works fine, maybe it has something to do with the debugger.
