TDA4VH-Q1: TDA4VM / VH: CCS ROV modules do not support Hwi & Sysmin

Hi TI CCS / Jacinto Experts,

Customers are doing some CCS(version 12) based project on TDA4VM / TDA4VH SDK8.x. As we could see from the below CCS ROV guide, there are many modules including Hwi & SysMin.

https://software-dl.ti.com/ccs/esd/documents/rov_guide/html/src/rov.html#id1

Hwi, SysMin, & other modules shown in the above picture have many useful functions & could make customers much more convenient to debug & implement their own projects. Hence, customers are very interested to have them. 

However, the ROV guide provided in the TDA4VM / TDA4VH SDK8.x PDK shown below only describe the FreeRtos module.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_04_00_06/exports/docs/pdk_jacinto_08_04_00_21/docs/userguide/jacinto/developer_notes/freertos_ccs_rov.html

I am trying to help customers to have other modules like Hwi & Sysmin. But seeing from the coding logic shown below, there is only FreeRTOS.rov.js available in the SDK that could be imported by syscfg_c.rov.xs. That could be the reason on the CCS only FreeRTOS module could be seen. 

May I know if it is feasible that if any other SDK from other chips have Hwi or Sysmin rov jason files, could we place them here in TDA4VM / TDA4VH SDK8.x to make it available? If so, could anyone help to provide these files? Thanks! These modules could enhance customers' efficiency.

Kind Regards,

Kevin

    Hello,

    I can only comment from a general tools standpoint. There is typically more information in ROV for SYS/BIOS than FreeRTOS. Also, what is visible will be determined by how the project (and RTOS) is configured.

    The device experts can chime in further

    Thanks

    Hi Kevin,

    I really doubt this is possible in the current implementation of Hwi. Hwi module internally uses CSL code ie intc module to configure interrupt. whereas i see that roc.xs file is trying to get all information using FreeRTOS objects.. I will check with the team and confirm this with the team. If this is possible, will share the information on this.

    Hi Kevin,

    This is not supported in the current SDK and will be a new requirement if this needs to be supported.. This may require good amount of changes in the Hwi modules, so requires to raise requirement and plan for it..
