Hello all,
Apparently I must power cycle my STM32-E407 to get the Ethernet block to function (i.e. seeing the two LEDs at the bottom of the RJ45 lit). Strangely, depressing the reset button does not yield a functioning Ethernet block which makes debugging of network applications impossible. This did not use to be the case using revision B !
I have a lwIP TCP/IP stack running on the board.
Is there a work-around? Is this a software issue?
Any comments will be appreciated.
Thanks in advance,
Tamir
Is it possible that the PHY transceiver must be manually reset...?
Solved - auto negotiation was started while PHY chip was in reset...
hi tamir
i can not initialize ethernet block properly. could you share your initializing code?
thanks
