I have used the WIZ811MJ module and just put to 1 with a 10K the /CS line to put the module in SPI mode, then you have to move the /RESET to 0 and back to 1 and then after connecting to the network the LEDs flash accordingly without further action.
I did not look good if the pattern you used definitely have to take as a reference the module that I told you and start from there. I see from the pdf that we are a little too much pull-up resistors and with the WIZ811MJ module does not serve.[/quote]
I put 3.3v to /CS pin directly from MCU output pin.
I connect chip to network after that, i reset chip but nothing is changed. I suspect PHY because i can communicate with chip via SPI i can open socket, get socket’s state but nothing on physical side.
Can RESET_BG pin cause such a problem ? I connect it to ground with 12.25 kohm not 12.3 kohm.
