TDA4VM: Integrate Autosar On MCU1 , MCU3 , MCU4

Walid Abdelaal

Part Number: TDA4VM

Tool/software:

Hi ,

I am currently configuring the classic Autosar stack for MCU1, MCU3, and MCU4,
A single binary output includes all Autosar configurations, OS and startup code.
MCU1 is initialized by the SBL, while MCU3 and MCU4 are initialized by MCU1.

To proceed with this setup, I need clarification on the following points:

Starting/Resetting MCU3 and MCU4:
- What are the required instructions to start or reset MCU3 and MCU4?
- How to flash three core using one executable ?
Vector Table Specification:
- Do we need to define a separate vector table for each MCU?
- If so, what are the respective addresses for each core?
Multicore Image vs. Linker File:
- Should we create a multicore image, or can we rely on the addresses specified in the linker file for proper execution?

Hi,

What do you mean by single binary on all three cores? can you please elaborate?

Single Binary >> One executable file generated during build process , because autosar config are bundled together for three cores

If you are using SciClient, UDMA drivers, its not possible to run single binary on all three cores. Also mcu1_0 needs to integrate SciServer, so i really doubt this is possible.

Generally Speaking what we possible way to start MCU3 From MCU1 , while MCU1 Started from SBL.
please share example to start MCU3

hi,

mcu1_0 runs SBL and SBL can load another firmware on mcu3_0. If you are looking for this solution, this is possible. So can you please confirm it?

we are not planning to use SBL to load Firmware to MCU , can u please tell me alternative to load MCU3 ( linux ,sciserver , ...)

How MCU1 will release core (MCU3/4) ?

Sorry, didn't it. what do you mean releasing the core? If you mean powering up these cores, yes, mcu1_0 can power up these cores.

Can u list interface or register needed to be set to power up R5 Core from MCU1 ?

Hi Walid,

Its not registers, we need to use Sciclient API interface to power on and to even set the start point. Please refer to existing example in SBL to understand this flow.

Currently am not able to start MCU2 from MCU1 after is loaded by SBL .

Please find procedure i use to start MCU2 :

/* Step One : Request cores from SYSFW */
status = Sciclient_procBootRequestProcessor(SCICLIENT_PROC_ID_R5FSS0_CORE0, SCICLIENT_SERVICE_WAIT_FOREVER);
while (status != BOARD_SOK)
;

/* Step Two : Set Process Configuration */
status = Sciclient_procBootSetProcessorCfg(&proc_set_config_req, SCICLIENT_SERVICE_WAIT_FOREVER);
while (status != BOARD_SOK)
;

/*Step Three : Set CLK Config */
Sciclient_pmSetModuleClkFreq(TISCI_DEV_R5FSS0_CORE0,
TISCI_DEV_R5FSS0_CORE0_CPU_CLK,
(1000000000),
TISCI_MSG_FLAG_AOP,
SCICLIENT_SERVICE_WAIT_FOREVER);

// Step Five : Un-halt Cores
status = Sciclient_procBootSetSequenceCtrl(
SCICLIENT_PROC_ID_R5FSS0_CORE0,
0,
TISCI_MSG_VAL_PROC_BOOT_CTRL_FLAG_R5_CORE_HALT,
TISCI_MSG_FLAG_AOP,
SCICLIENT_SERVICE_WAIT_FOREVER);
while (status != BOARD_SOK)
;

// Step Six : Relinquish control from SYSFW
status = Sciclient_procBootReleaseProcessor(SCICLIENT_PROC_ID_R5FSS0_CORE0, 0, SCICLIENT_SERVICE_WAIT_FOREVER);
while (status != BOARD_SOK)
;

Can u please advice what is missing here ? what is list of module that need to be initialized for MAIN domain ?

Do you mean you are using your own code? Is it possible to use SBL existing APIs to start and power on these modules? This APIs are supported and validated on all platforms, so my recommendation is to use existing APIs please.

Am looking to start MCU3 from MCU1 outside SBL context

Can you please confirm sequence i shared ?

Hi Walid,

Do you mean to port this code to some different OS? Then can you please take functions defined in the SBL?
