Connection issue using STM32

[lowliexin]

Hi,

I want to use Mongoose built-in TCP/IP stack for my custom board. The log message appear in the serial terminal shows the connection is ready. However, when I trying to use PC ping the device, the device can receive the signa but the PC keeps showing timeout. Please refer the description below for the details.

Board: Custom with STM32H7 series
Interface: RMII
Platform: Keil MDK
Compiler: ARM v5
OS: Bare-metal
IP stack: built-in mongoose TCP/IP stack
PC IP address: 192.168.1.10
Device IP address: 192.168.1.24 (not DHCP)
PC and device mask: 255.255.255.0

Can anyone tell me what goes wrong?

You have a custom board, so evidently what is wrong is that anything is not properly configured according to your board, either PHY address or memory placement or cache settings.
Not a Mongoose issue, but your issue. If, after reading the wizard README (all of it), and the two docs that follow, you need further help, I suggest you ask for more help at the Wizard DIscord.

BTW, we don't fully support the ARM v5 compiler, and for v6, make sure it takes our GCC-like memory placement attributes. Otherwise, you're on your own. Follow code tutorials here if available for the closest micro, and if you are a paying customer please contact Support as per your contract. Thank you.
