SYSCONFIG: TDA4VM: Cannot modify .start_resouce for MCU NAVSS Interrupt router

Marina Lenza

Part Number: SYSCONFIG

Hello TI,

I am using the Sysconfig and K3_respart_tool to enable resources for DMA in our board.

I am trying to match the configuration in the tool with the configuration in our rm-cfg.c file, since we don't have the .syscfg that generated it.

I am not being able to find where and how to change the .start_resource for the MCU NAVSS Interrupt router. Which field should I modify?

Currently is 4 assigned:

		/* MCU NAVSS Interrupt router */
		{
			.start_resource = 4,
			.num_resource = 20,
			.type = RESASG_UTYPE (J721E_DEV_MCU_NAVSS0_INTR_0,
					RESASG_SUBTYPE_IR_OUTPUT),
			.host_id = HOST_ID_MCU_0_R5_0,
		},

And I would like to be 12, like this:

		/* MCU NAVSS Interrupt router */
		{
			.start_resource = 12,
			.num_resource = 20,
			.type = RESASG_UTYPE (J721E_DEV_MCU_NAVSS0_INTR_0,
					RESASG_SUBTYPE_IR_OUTPUT),
			.host_id = HOST_ID_MCU_0_R5_0,
		},

Thank you,

Marina

Marina,

This tool calculates and generates this file, it calculates the number of resources available and number of resources allocated in the tools and based on that it assigns start_resource variable. It cannot be controlled in the tool. Why do you require this resource to be starting at 12? Is it because of some hard coding? Can you check who else is using this resource and modify their usage to change start resource ?

Hi Brijesh,

I am trying to match the configuration on the sysconfig tool with the one that we have currently on the board, so after I can allocate more resources without modifying what we already have.

I checked on our repository and the rm-cfg.c, with the resource starting at 12, was taken from the TI Git:https://git.ti.com/cgit/k3-image-gen/k3-image-gen/tree/soc/j721e/evm/rm-cfg.c

Where can I find the j721e-evm.syscfg that generated the rm-cfg.c?

Thank you and Regards,

Marina

Hi Marina,

Can you please use SDK 8.6? i see SDK8.6 has start_resource as 12 for this resource and also you could find corresponding json file in board-support/k3-respart-tool/out/j721e-evm.syscfg.
