STM32F769BIT custom board - Ethernet issue

[Sayan]

Hi Team,

I made a custom board using STM32F769BIT microcontroller using with the DP83867 PHY in MII mode, but I am not able to ping it. What could be the possible reasons? 

I did Memory configurations for TxDecrip, RxDecrip, LwipHeap like this.

.lwip_sec (NOLOAD) :

. = ABSOLUTE(0x2007C000);

*(.RxDecripSection)

. = ABSOLUTE(0x2007C0A0);

*(.TxDecripSection)

. = ABSOLUTE(0x2007C140);

*(.LwIPHeap)

also my SRAM configuration is like this_

MEMORY

RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 496K

SRAM2 (xrw) : ORIGIN = 0x2007C000, LENGTH = 16K

FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 2048K

I am using the 10pin STM32 debugger, but I am not able to see the stack usage there, when I press the debug button.

Is it due to code or due to the debugger? For this should I need the 20pin debugger?

Thanks,

Sayan Das

Hello @Sayan,

I suggest you provide the current status of your debugging process so I can assist you and help speed it up. This way, you can get your solution working in a shorter time.

Best regards,
