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?
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:
