FIDO5200 Transmit packet

Thread Summary

The user is experiencing issues with the FIDO5200 where the TXEN pin does not rise when calling REMS_StdXmitPacket() and no interrupts are generated on the interrupt lines when a packet is received. The support engineer requested schematics and logic analyzer traces for further analysis. The user provided traces showing RXDV rising with data on the bus, but no interrupts are generated.

Hello,

I am trying to set up the FIDO5200 with a STM32 CPU. In the FIDO5000 drivers there is a function REMS_StdXmitPacket() used to transmit packet. When I call this function the TXEN Pin of the predefined port is never rising. And when a packet is received from the external PHY, the RXDV pin is rising and data are present but the FIDO is never rising any interrupt on any interrupt line. Can you give more information about the internal FIDO500 transmit/receive process ? 

Thanks
