7608.Ethernet working code for RMII MASTER in DP83640.rarHi,
Thanks for your reply.
i changed ID for DP83848 in
#undef DP83848_PHY_ID
#define DP83848_PHY_ID (0x20005C90)
but etharp_gratuitous ARP is not happening.
I uploaded working RMII MASTER Mode-->TCP/IP code for DP83640 is fine. but presently we are using DP83848 it doesn't have RMII master mode .so i changed to RMII slave but etharp_gratuitous ARP is not happening . Please Suggest what change for DP83848.
Signal Status of DP83848 :
1) RMII CLK as 50MHz(input).
2) PFBOUT,PFBIN1 &PFBIN2 - 1.76V.
3) TXD_2 & TXD_3 grounded.
4) RX_DV/MII_MODE - connected to Pullup resistor.( during RESET this pin high , after that it is becoming Low).
5) RX_ER/MDIX_EN- Pullup resistor removed.
6) CRS/CRS_DV/LED_CFG - Pullup resistor removed.
7) Reset is taking nearly 200ms.
8) RBIAS- 1.23V.
Status of Register in DP83848 . i uploaded in doc file7875.Ethernet_PHY_DEVICE_REGISTER_STATUS_APM.docx
i have uploaded Schematic for DP83848.
what is Difference between RMII MASTER & RMII SLAVE? .
what change i have to make.we are waiting for your reply .
