Hi Team,
I have a question about DP83848K.
DP83848K RMII I/F is connected with STM32F7 and external 50MHz is connected with STM32F7 and DP83848K.
following shows ideal procedure but read address is 0x7894(no change) and Linkstatus doesn't become 1 then timeout.
TD/RD pulse doesn't output.
[ideal procedure]
1. Active Low input to RESET_N_DP83848K(release RESET)
2. initialize HAL driver STM launched for STM32F7 ether
3. read address 01h and wait until Linkstatus becomes 1.
[test setup]
STM32F7 --RMII-- DP83848K --LAN cable-- Hub
in order to avoide this timeout, are there any additional register setting or sequence?
Regards,
Kai
