I am using the W7500P-S2E on a self developed Board.
I got a problem with the RS232->Ethernet Signal.
Receiving from the Ethernet:
Received Data goes trough on the U_TXD0 (PA13/Pin43). It is functional and an other RS232 Device gets the Data. Works fine.
Sending back on the U_RXD0 (PA14/Pin44) is correctly but from there… nothing on the Ethernet. Stays dead silent. -> The signal comes correctly on the W7500P Pin44.
