TDA4VEN-Q1: LDC node freezing issue

Hi,

Which SDK release are you using? In one of the later release, we had by default enabled WDG timer, probably, that's creating LDC to get stuck. Can you try disabling WDG in LDC?

Hi

The SDK release is 11.01. How can I close WDG  in LDC

Set below variable to FALSE (UFALSE) in vhwaM2mLdcSetHtsCfg API in source\drivers\vhwa\src\drv\vhwa_m2mLdcApi.c and rebuild the SDK.

htsCfg->enableWdTimer = (uint32_t)UTRUE;

Hi

I'm testing and I want to know what this parameter does, and why it causes freezing issues.

WDG timer is by default enabled in this release. LDC being 2D module can potentially see this timeout value in the usecase environment, so its disabled for LDC.

Hi

Can I understand it this way: WDT time is a timer, and if the processing time of a single frame in the LDC node exceeds a certain time threshold, it will cause it to freeze?

Yes, that's correct.
