AM2634-Q1: AM2634-Q1: Autosar : Adc_StartGroupConversion API does not provide updated ADC results in the same ignition cycle

Ashish Sebastian

Part Number: AM2634-Q1

High Prio :

MCAL version : MCAL_AM263x_09.00.01.01

We are triggering Adc_StartGroupConversion for ADC channel groups, mapped for ADC SW trigger, cyclically at every 5ms, as in the screen below.

We see that the ADC result buffers do not show us an updated ADC conversion result for any of the channels mapped to the ADC group triggered by the SW trigger.

I am monitoring ADC0_1 to which I vary the Voltage inputs. ADC0_1 is the 1st channel in the group of 4 ADC channels which is mapped for SW trigger.

I can only see the updated voltage value in the next ignition cycle once i reset the ecu.

Test on LP eval board.

Temporary fix : He have currently changed all the SW triggered groups to be triggered as HW triggered groups based on EPWM0_A.

motor spinning tests are blocked due to the improper ADC conversion results.

Hi Ashish,

Can you share the ADC group configurations?

Hi Akshit,

Can we have a short alignment tomorrow at 11am UK time please if it work fine for you. I have updated the parallel ticket as well. I do not have any conversion results for the ADC SW group SoC.

Hi Ashish,

Sorry for the delay.
Right now we're checking and trying to reproduce the issues locally, that's why the ADC group config would help.

Regards,
Akshit

Hello Akshit,

I have tried to attach the xdm files. but it does not seem to get attached unlike the .c file.If xdm would help you better, please send me a mail to ashish.sebastian@empelsystems.com.

Hi Ashish,

Thanks for this, we don't need the xdm, but if you could provide the complete IoHwAb_Cyclic5ms function that would help.

Thanks

I hope this helps

Thanks Ashish,

Can you check the same setup with interrupt mode and let me know if it's working?

And can you also share what exactly is being done after Adc_ReadGroup function and before calling IoHwAb_Cyclic5ms function again?

Regards,
Akshit

Hi Akshit,

I have already tested the interrupt mode long time back. It was working fine. But in our project polling mode is what is needed to be used and hence the new feature was added in the latest release. Sunil and Pratik knows the background.

Nothing specific is being done after Adc_ReadGroup. I am just copying the ADC converted value into the RTE buffers to be provided to the user component. something like this.

Hi Akshit,
Do you have any updates on the topic? Do you think a short alignment would be helpful? I can share my screen and discuss on the open points. I have a window until tomorrow afternoon UK time. after then i will only be available the next week as i have demo sessions this week starting Wednesday afternoon.
