Board: NUC980-ETH2UART
Ethernet module: WIZ810Sio
Driver: From linux kernel 4.7 w5100.zip
Device tree: nuc980-eth2uart.dts.txt
I want to use W5100s as main SPI ethernet driver with board NUC980-ETH2UART
Wring:
- SPI0. PD8 (CSn), PD9 (CLK) , PD10 (MOSI), PD11(MISO)
- INTn: PE12
- RSTn: PG9
I have try to bringup this board. The driver seem that it can be recognized by linux kernel.
I can use 2 command below, if I disconnected one wire, the 2 command will be invalid
ifconfig eth2 up
ifconfig eth2 192.168.0.100
But due to the INTn and RSTn is not defined in device tree, so I cannot ping to PC ---> The connection is not okay.
I have tried to find the sample of config the interrupt but not found.
Do you have any sample or the same experience with W5100/W5500 SPI?
