TDA4VM: Main Domain Reset

Part Number: TDA4VM

Hello,

I am creating MAIN domain reset by calling function,

status = Sciclient_pmSetModuleRst (modIdx,

0x1U,

SCICLIENT_SERVICE_WAIT_FOREVER);

However, I do not see the main domain reset. MAIN domain is still active, checked reset registers and also the prints from A72 and MAIN domain is intact.

Additionally called,

status = Sciclient_pmSetModuleState (modIdx,

TISCI_MSG_VALUE_DEVICE_SW_STATE_AUTO_OFF,

TISCI_MSG_FLAG_AOP |

TISCI_MSG_FLAG_DEVICE_EXCLUSIVE |

TISCI_MSG_FLAG_DEVICE_RESET_ISO,

SCICLIENT_SERVICE_WAIT_FOREVER);

to put MAIN domain to off before reset. However, do not see any impact.

I see that there was already question in E2E: TDA4VL-Q1: Warm Reset Main R5FSS0 core1 - Processors forum - Processors - TI E2E support forums. Is there any update on the question here. Is there any software update?

I believe there are some additional steps required here as well.

Let me check this and get back. Should be able to revert back by Thursday.

Hi,

Is this the same query as https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1341117/sk-tda4vm-issue-sw-reset-to-main-domain-and-mcu-only-mode/5118147#5118147 ?

Hello Parth,

There is difference,
In the Sirisha's code (https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1341117/sk-tda4vm-issue-sw-reset-to-main-domain-and-mcu-only-mode/5118147#5118147 ?) the reset function is directly used from LPM code, which uses Lpm_swResetMainDomain(), inisde this TISCI_MSG_SYS_RESET is used, and this causes MCU to break.

In my example, I am using Sciclient_pmSetModuleRst (), which uses TISCI_MSG_SET_DEVICE_RESETS.

In this case there is no reset.

Do we have any different procedure for AUTOSAR? Sci for AUTOSAR is integrated but still no reset if Sciclient_pmSetModuleRst called.

Would you please confirm whether any relevant discussions are still ongoing in this thread https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1342275/tda4vm-stop-hal-main-domain-and-reboot-entire-soc ?
