TDA4VM: Questions about R5F MCU3_0 GPIO interrupt config

Hi experts:

      My first code picture was wrong uploading, in fact below:

the other pictures  and debug result are same as above, thx.

Hi,

Can you please confirm the following:

SOC - TDA4VM
Interrupt source - GPIO0 Bank 1
Destination - MCU3_0

If yes, then the dst_host_irq value should be something from 176-191.

Can you please try the above and see if it works for you?

Regards,
Parth

Hi Parth:

    I fixed the code according to your suggestion:

Then the debug result :

and the retVal of Sciclient_rmIrqSet is 0xFFFFFFFF .

I dont know why.

Could you please help me check if there are any errors in my configuration?

valid_params = 3;

src_id = 105;

src_index = 1;

dst_id = 247;

dst_host_irq = 177;

Or maybe I'm missing some preconditions？

Can you provide a simple example for my reference?

Looking forward to your reply.

Lin

Hi Parth:

          Sciclient_rmIrqSet   setting is OK now. I have a new trouble and few question.

question:

          Why  the dst_host_irq value should be something from 176-191 ?  (SOC - TDA4VM  /  Interrupt source - GPIO0 Bank 1  /  Destination - MCU3_0)

Why not the following：

Trouble:

         I set the GPIO input interrupt trigger is GPIO_CFG_IN_INT_BOTH_EDGES.  Then input some pulse to the pin (GPIO0_31), the callback function did not enter and mcu3_0 met a exception and enter a error hook. (dst_host_irq value set  to 257 or 177, the case always happen.)

         I had check the register GPIO0_ITSTAT01, is 0x0000 0000u.

Or maybe I'm missing some preconditions？

Can you provide a simple example for my reference?

Looking forward to your reply.

What changes did you do for this?

Please refer to the documentation https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721e/interrupt_cfg.html#gpiomux-intrtr0-interrupt-router-output-destinations The destination Index for the J721E_DEV_R5FSS0_CORE0 from GPIOMUX_INTRTR0 lies between 176 to 191

You can refer to the GPIO led blink example from the PDK at <PDK>\packages\ti\drv\gpio\test\led_blink\src

Dear Parth:

       Thanks for your reply.

I  was using the debugger(XDS560) to step through debugging，it always fail.  If you let the program run normally, it's OK.

Now I can enter the interrupt callback functions successfully, the OK pins are AB23(GPIO0_31) and AG27(GPIO0_58), and their interrupt numbers are 257、259，as follow:

I also need to config the interrupt for GPIO2 Bank1 and GPIO2_Bank2，The  Sciclient_rmIrqSet   setting is OK ,but the callback function can't entry.  Is there anything else to note about GPIO port2's interrupt configuration？

Looking forward to your reply.

Can you share the parameters you are passing to Sciclient_rmIrqSet API in this case?

Please share the same for this case as well.

Also, can you please check if you are getting the raw interrupt in GPIO2 case? Please refer to the FAQ https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1158072/faq-tda4vm-pdk-interrupt-registration-for-r5f-using-osal?tisearch=e2e-sitesearch&keymatch=TDA4VM%3A%20PDK%20Interrupt%20registration%20for%20R5F%20using%20OSAL#

Hi Parth ：

        Thank you for your patient guidance.

My Sciclient_rmIrqSet API params as follow: 

AB23 (gpio0_31):

rmIrqReq.src_id = 105
rmIrqReq.src_index = 1
rmIrqReq.valid_params = 3
rmIrqReq.dst_id = 247
rmIrqReq.dst_host_irq = 176

AG27(gpio0_58):

rmIrqReq.src_id = 105
rmIrqReq.src_index = 3
rmIrqReq.valid_params = 3
rmIrqReq.dst_id = 247
rmIrqReq.dst_host_irq = 177

AC21(gpio2_28):

rmIrqReq.src_id = 107
rmIrqReq.src_index = 1
rmIrqReq.valid_params = 3
rmIrqReq.dst_id = 247
rmIrqReq.dst_host_irq = 178

AD26(gpio2_46):

rmIrqReq.src_id = 107
rmIrqReq.src_index = 2
rmIrqReq.valid_params = 3
rmIrqReq.dst_id = 247
rmIrqReq.dst_host_irq = 179

Y23(gpio4_29):

rmIrqReq.src_id = 109
rmIrqReq.src_index = 1
rmIrqReq.valid_params = 3
rmIrqReq.dst_id = 247
rmIrqReq.dst_host_irq = 180

Until now，all the pins above can register irq successfully through Sciclient_rmIrqSet.   However, only two pins(AB23 & AG27) can enter the interrupt callback function.

I had check the other failed pins' GPIO register and CTRLMMR_PADCONFIG register,  the registers are correct! 

I feel confuse why the GPIO2 and GPIO4 can't enter the callback fuction. Are there any other registers that can be reconfirmed?

Looking forward to your reply.

Lin

This FAQ is very help for me, thank you！

    I set 8 bank GPIO interrput as follow:

VIM_***_j   ( j = 5 )  register as follow :

VIM_PRI_INT_j  register as follow :

VIM_VEC_INT_j  register as follow :

int VEC address as follow:

Thanks.

Moreover,

I try fix gpio0_31  to  intnum = 178, the interrup can work normally. Fix gpio2_28 to intnum = 176, the interrupt can't work normally. So I guess the interrupt fail in GPIO2 might have something to do with GPIO2 config. I check GPIO2 as follow:

Anything else to check for this ?

Looking forward to your reply.

Lin

By the way, I'm using the Vector's AUTOSAR os on MCU3_0.

Thanks

Hi ,

Apologies for long silence. Is this issue still open?
Can you please mention the current state of the issue?
