TDA4VH-Q1: vpac1 very slow after Ethernet firmware disabling

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Tool/software:

Hi

We are experiencing a slowdown in vpac1 (but not vpac2) by an order of magnitude when running our application on Tda4VH.
This happens after applying a fix to enable HDMI monitor usage.

Our sdk is 09.02.05 with some modifications provided by you:
c7x-mma-tidl_j784s4_10_00_05_00, mmalib_obj_C7120_10_00_00_09.

The fix we've applied is located at the following file:

sdk_builder/vision_apps_build_flags.mak line: 116

ifeq ($(RTOS),SAFERTOS)
ifeq ($(SOC),j784s4)
BUILD_ENABLE_ETHFW=no
endif
endif

We have removed the first ifeq (setting BUILD_ENABLE_ETHFW to no).

We would like to understand what is the correlation between VPAC1 to the module, and would like to have you assistance in solving our issue.

Thanks in advance,
Oren
