hi we are using mcbstm32c board. we used and tried every examples (we downloaded examples from keil ) on this board with keil . all examples worked succesfully except network examples . we could not communnicate board to pc . we used cross-over cable . and we did every stage on datasheet. but we could not make it . how can we fix it?
I had a similar problem but by reviewing Wireshark logs I have found that the NIC connected to the board didn't resolve correctly the board address. I had to add the MAC address of the board into the ARP table of the PC for this network card in order to get both communicate together.
Check with the command "arp -a" in a command prommpt.
Maybe that could help you.
Did you have this NIC issue when doing a soft reset or a power cycle?
Sometimes, I had it when the external PHY is not done resetting when the ST32 is already started executing.
When this every now and then event happened, the board acted like it was communicating to the PHY, and sending messages, but the board would not transmit.
To check,run wireshark on the PC, and then compare against the debug messages from the debug variant of the TCP stack:
