Hi,
There is bug at file nx_stm32_eth_driver.c version x-cube-azrtos-h7 3.4.0 at line 1757 inside function _nx_driver_hardware_initialize().
this line:
FilterConfig.BroadcastFilter = ENABLE;
should be replaced with:
FilterConfig.BroadcastFilter = DISABLE;
This is due to changes at HAL function HAL_ETH_SetMACFilterConfig() between versions 1.11.3 and 1.11.4 where logic of BroadcastFilter property was reversed.
