Check your driver's PSTOP value. now, i change the PSTOP to 0x60, it still get the messages > > Also, it would be worth checking your ISA-like bus is correctly > configured. Bus-width, clock, wait-cycles, setup/hold time, etc. our board is a FPGA board for embedded system, there is no ISA, and use memory map IO, is there anything need to configure? > > --- > Atsushi Nemoto > now i printk the ISR and RSR value when bogus packet accepted, are these two registers correct? messages as follow NE_EN0_RSR = 81 NE_EN0_ISR = 1 eth0: bogus packet: status=0xef nxpg=0x5e size=1518 NE_EN0_RSR = 1 NE_EN0_ISR = 1 eth0: bogus packet: status=0xae nxpg=0x50 size=1518 NE_EN0_RSR = 1 NE_EN0_ISR = 1 eth0: bogus packet: status=0xb7 nxpg=0x5c size=1518 NE_EN0_RSR = 1 NE_EN0_ISR = 1 eth0: bogus packet: status=0xae nxpg=0x4e size=1518 NE_EN0_RSR = 1 NE_EN0_ISR = 1 eth0: bogus packet: status=0xcb nxpg=0x5a size=1518 NE_EN0_RSR = 1 NE_EN0_ISR = 1 Best regards zhuzhenhua
