EDK 11.1 - ML410 TestApp_Peripheral fails

I generate a system with BSB:

  • RSA232 UART16550
  • 8-bit LEDs
  • 256M DDR2
  • TriMode_MAC_MI
  • SystemAce
  • MGT


With all configurations set to default, I just generate the bitstreame file. My network connectin is through a cable hooked to a 100M Switch. I have no problem using it with XPS_EthernetLite IP for TestApp_Peripheral.

 

However, the  TestApp_Peripheral fails, the "100M" led is turned off, and I get error message like:

 

Temac: Rx packet rejected

TxBDs were not ready for post processing

 Does anybody has success in using LL_TEMAC on a ML410 board?

Re: EDK 11.1 - ML410 TestApp_Peripheral fails

I'm debugging the TestApp_Peripheral for Temac.

 

Before sending and receiving frames, "TemacUtilEnterLoopback" is executed. This program does two things: 1) reset Phy and 2) bring loopback.

 

1) is done by  XLlTemac_PhyWrite(TemacInstancePtr, PhyAddr, 0, PhyReg0 | PHY_R0_RESET); ---PhyReg0 is speed 100M for MII.

This is OK. When resetting, all EMAC Leds become off; then after a while, the 100M speed LED is on.

 

2) is done by  XLlTemac_PhyWrite(TemacInstancePtr, PhyAddr, 0, PhyReg0 | PHY_R0_LOOPBACK);

However, after this function is executed, the 100M speed LED is off again - all LEDs are off.

Is this a problem, indicating that ethernet link is lost?

 

 

Also, the RX led never boards - I guess that's nothing is received so that I get errors like " Temac: Rx fifo over run" and "Temac: Rx packet rejected".
