I am using CUBEMX Version      6.17.0

STMCUBE IDE                            2.1.0

FW Package name & version     STM32Cube FW_H7 V1.13.0

Enabled LWIP ETH With FREERTOS CMSIS2

same settings did with cmsis version 1 it's working but with cmsis version2 NOT Working

I configured on internal Timer TIM1 

as soon as I connect Eth Cable program counter not reaching threads & Timer callback / TIM6(systick update).

I checked in fault handlers it is not reaching here 

ETH State in eth handler is (READY STATE --> START STATE)

Error code in eth handler is zero.

Here I have attached my .ioc file

I have updated flash ld file as per repository code

Also with the recent update on CubeMx, I can't go back to CMSIS_v1 for the STM32H7 boards.
