Hello, I´m trying to run the FreeRTOS demo "lwIP_Demo_Rowley_ARM7" build with gcc on a selfmade board. It’s based on the ATMEL AT91SAM7X-EK schematic. The FreeRTOS is basically ok. The LEDs are blinking and I can communicate with the USB Port. Further I use the Phy (DP83848I) in state of the original PHY which use the developer of FreeRTOS. Now I can communicate with the Phy over the MDIO-Interface. Link is stable up and running. We get Links to the ethernet with 100 and 10 MBit. But I don’t get an receive Interrupt on the EMAC. The data (Rx0-3,Rxdv,Rxclk) from the Phy are on the Pins at the AT91SAM7X256 are measuered with an oscilloscop. The pinning between the ARM and the PHY looks like this: ARM  PHY PB2  TX0 PB3  TX1 PB10 TX2 PB11 TX3            PB1  TX_EN PB0  TX_CLK PB5  RX0 PB6  RX1 PB13 RX2 PB14 RX3        PB15 RX_DV        PB7  RX_ER            PB17 RX_CLK    PB8  MDC        PB9  MDIO            PB16 COL        PB4  CRS    PB26 PowerDown                        Best regards, Michael                

This is a bit processor specific rather than FreeRTOS specific.  I would suggest posting the same message on the SAM7 Yahoo group.  You might get a more expert reply.

Thanks for the hint, I will try this. Best regards, Michael
