TDA4VM: GPIO bank4 interrupt can not set success

Jafar Fu

Part Number: TDA4VM

Hi,

I use GPIO0 many PIN as input interrupt in mcu2_0, if 16PIn as a bank, these IO are in bank0 to bank 4;

I set Bank0 to Bank3 interrupt is success from 184 to 187, but bank4 set to others , it is NG

( 176~183 no matter which bank set, always NG, just can set from 184, I also try to release 188, then set bank4 again, NG)

Please help me how can i do for the bank4 interrupt?

Below is MCU2_0 for GPIO interrupt Numbers, in blue these can set OK, then for bank4 interrupt , i try to set from 0~512, all Nums is NG

Hi,

Can you confirm that interrupts are enabled for Bank 4 by checking GPIO_BITEN register?

Hi,

Yes, i'm sure the GPIO_BUNTEN value is 0x1f;

I also check below:

delete Bank0 interrupt,and use 184 setting Bank4 interrupt, Bank4 interrupt is success.

Hi Jafar,

Apologies for delay in response.
Actually, there are only 4 interrupts reserved for each core on resource manager which is why I believe you are not able to configure 5th interrupt.
Please refer to the thread e2e.ti.com/.../3953217

Hi Parth Nagpal，

About the sentence ‘Otherwise, this would require change in the resource manager.‘ in e2e.ti.com/.../3953217, can you give some advise in case no hardware change?

Hi Parth Nagpal，

Sorry.

Change the resource manager is the mothed, i understand.

Thanks!

Hi Jafar Fu,

Are you still looking into allocating GPIO interrupts to specific core? can you please provide the SDK release you are using and the code for which you want to allocate the GPIO interrupts?
