Hi.
I use a DP83848w with stm32f107. ARM program and PHY work successfully for first time and I got my socket connection on Hyper-terminal, but the link led turned off when I reseted the board for debugging and it never be turn on !
I cant find any issue on software after many reset and analyze the PHY register.
BMCR is 0x3100 & BMSR is 0x7849 -> no linking
I turned off the board and turned it on again after 30 min.(I worked on other things.) Its OK again! but when I reseted, no linking available.
I tested :
1- 10M half duplex, no link.
2- loop-back cable,no link.(loop-back cable tested before with a Ethernet switch and led of switch turned on)
Its seems that my PHY cant negotiate or create active link for a reason.
whats the problem(s) ?
Thanks.
