STM32F746+LWIP+CMSIS2 Not Working BUT With CMSIS1 Working

[lavanya]

I am using CUBEMX Version   6.10 

STMCUBE IDE                        1.16.0

FW version                               F7V1.17.0

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

Hello @lavanya ,

unfortunately, there is no support for cmsis V2 FreeRTOS for F7 series.

I have input a ticket (ticket number 203486 for internal reference only) to remove the option for cmsis v2 for FreeRTOS in cube MX.
