Ethernet works smoothly but after addition of small code it does not give ping response.

[ADank.2]

Hello,

I am using STM32F429ZI Freertos+TCPIP+TFTP . Ethernet works smoothly but after addition of small code which includes some global array of 2KB it does not give ping response. when I uncomment the global array then again it works properly. What is the reason. I have suffiecient Free SRAM Memory. Till Now SRAM Usage is 57%.

What ram region are you creating your array in? TCM and ethernet cannot be used together.

We are not using TCM. The array is declared globally. So it is in .bss section of SRAM.

Thanks,

Your description is??? which includes some global .... when I uncomment the global array

and showing code can help you no this ...

And my glass ball say you use array that isnt volatile on unblocking func...
