Hello
Im wondering how to configure the DP83822 for RMII Master mode.
I first tried it by writing to the register 0x17 and 0x462 via the SMI. I noticed that when I write to the IOCTRL1 register at address 0x0462 , it doesn't take over my value. When I read the value after writing, I still see the old default values.
I then tried to setup the RMII master mode via bootstrap. I inserted a pullup and a pulldown resistor on the RX_DV pin (Mode 3). When I did that, I can't read any phy register anymore via the SMI. I can measure the 50MHz reference clock on PIN RX_D3, which indicates that RMII master mode is set. However my communcation is still not working. Is there any further configuration I need to do? Why can't I acces the register anymore when appling the bootstrap?
Kind regards
