Part Number: AM2434
Other Parts Discussed in Thread: SYSCONFIG

Hi,

I am using the CC33xx MCU PackageR5 on AM2434.

Recommended SDK version: 8.5.0.45 and above
Currently used (for USB support):

AM243x SDK 8.6.0.45
SysConfig 1.14.0
TI Clang v2.1.2.LTS

I am facing an issue with interrupt routers on R5FSS0-0 core. Im using only one core

According to the `sciclient_defaultBoardCfg_rm.c`, R5FSS0-0 has 3 interrupt routers allocated: Router 7, Router 8 and Router 9

I attached the image below:

But in my application:

interrupt Router 7 is not working.
Only Interrupt Router 8 and Router 9 working.

For example: K7 Ball pin of am2434, monitoring the falling edge of the pin and triggerigering interrupt. when i use Interrupt router 7 it is not triggering interrupt. when i used router 9 interrupt is triggering.

My question:

How can I enable or correctly configure Router 7 so that all three interrupt routers work for R5FSS0-0?
Do I need to modify the RM boardcfg or any SysConfig settings? Why only twointerrput routers are working, i can't able to configure any other router, can you help to find the issue?

Thank you.

Hi Arun,

The router config which you highlighted in the above image is allocated for R5F0-0 core in secure context. (i.e. TISCI_HOST_ID_MAIN_0_R5_0) which has range 7-9.

For R5F0-0 core non-secure context, the host id will be TISCI_HOST_ID_MAIN_0_R5_1 which has router allocation with range 8-9.

You will need to update this entry and rebuild the board config blob. Also you need to rebuild the SBL example and flash it. Also rebuild the application to make it work.

Regards,

Tushar

Hi Tushar Thakur,

Thank you for the reply,

May I know from which document I can get those details of secure and non secure context.

And also can you provide any reference document to update and build the board config file.

To know details on resource allocation and host ID, please refer RESOURCE_ALLOCATION.
