TMDSCNCD263: Clarification in Category 1 ISRs before StartOS

Part Number: TMDSCNCD263

Hi Team,

Please clarify following queries related to CAT I ISR configuration.

  • We are trying to configure the Category 1 interrupt and following the vector OS document. for the category 1 ISR the mentioned some following sequence, we can do 1,2 and 4 points as per the below snippet. but we are struggling in 3rd step to enable the interrupt of category 1ISRs by directly manipulation the control registers in the interrupt controller.

  • Global interrupt flag/ interrupt priority register, we trying to locate in the technical reference document. but cannot locate. Could you please clarify and guide as to activate CAT 1 ISR? thanks

          

Thanks

    Hi Vivek,

    Are you using MCAL modules to configure CAT1 ISR?

    Thanks And Regards,

    Hi Sunil,

    Yes, we are using MCAL version- MCAL_AM263x_08.06.02.01.

    Thanks

    Hi Vivek,

    If you need to configure CAT1 category for MCAL modules then in the EB Tresos configurator or Vector DaVinci configurator you need to select interrupt type parameter to CAT1.

    For example:  In Adc module, AdcTypeofInterruptFunction to  ADC_ISR_CAT1

    Thanks And Regards,

    Hi Sunil,

    Yes, we have option.

    Let's assume GPT module, we have 5 interrupts, 4`s have CAT-2 interrupts and 1 alone CAT-1 In this situation from my understanding in EB we have a one option correct. how it is possible for different channels CAT-2 and CAT-1?

    If we changed the value option via Vector DaVinci configurator, then the vector mentioned some sequences, as I mentioned in previous comments. highlighted below.

                     Enable the Interrupt sources of category 1 ISRs by directly manipulating the control
                      registers in the interrupt controller.

    Could you please guide us without sys_vim library how to enable the Interrupt sources of category 1 ISRs and FIQ by directly manipulating the control registers in the interrupt controller.? If we have sample code for this, please share with us. 

    Note: We are not using the sys_vim library for Enable the Interrupt sources of category 1 ISRs by directly manipulating the control registers in the interrupt controller

    Thanks

    Hi Vivek,

    In MCAL We do not have per hardware instance interrupt CAT support but it is module level.
