Use easyweb with KS8721

Hadi Nasiri

Hi friends
I have designed a training board for LPC2368 and use KS8721BL as PHY.
I wana use Keil EasyWeb for my board but it does not work(I can't PING my board)

This is what I have done:
1- Change "DP83848C_DEF_ADR 0x0100" to "DP83848C_DEF_ADR 0x0001" in EMAC.h
2- Change "DP83848C_ID 0x20005C90" to "DP83848C_ID 0x00221619" in EMAC.h
3- build project
4- write Hex file on flash

Should I do anything else...?

What's the PROBLEM ?

Thank you for your attention

    Hi friends
    Thank you Hans and Andrew for your replies
    I'm familiar with debugging, but it's hard to debug PHY driver(EMAC driver) because its complex !
    As you said my hardware's too different from the one that program was written for(my board likes OLIMEX_LPC2478_STK) but I find out that Ethernet PHY(KS8721 and DP83848) are same basically.
    If you see uTaskerV1.4_LPC-5 program in http://www.uTasker.com you'll find out that it's possible to use KS8721BL instead of DP83848 or vice versa with a little change

    These are the changes to match the project to each chip (in app_hw_lpc23xx.h).

    #ifdef OLIMEX_LPC2378_STK // MICREL PHY KS8721

    #define PHY_ADDRESS_ (0x01 << Mode) // address of PHY on OLIMEX LPC2378-STK (RMII mode)

    #define PHY_IDENTIFIER 0x00221619 // MICREL identifier

    #define PHY_MASK 0xfffffff0

    #elif defined KEIL_MCB2300 // NATIONAL PHY DP83848

    #define PHY_ADDRESS_ (0x01 << Cool // address of PHY on KEIL MCB2300 (RMII mode)

    #define VNDR_MDL 0x09 // Vendor model number

    #define MDL_REV 0x00 // Model revision number

    #define PHY_IDENTIFIER (0x20005c00 | (VNDR_MDL<<4) | MDL_REV)// NATIONAL DP83848 dentifier

    #define PHY_MASK 0xfffffff0

    #endif

    I applied this simple change to my code(PHY_IDENTIFIER & PHY_ADDRESS) but it does not work and
    I can not PING my board !?
    uTasker Code is suitable for both MCB2300 and olimex_LPC2378_STK and ethernet Interface with LPC are same in both Keil and Olimex.
    What do you think ?
    How can I change easyweb program to use it on my board ?
    Thank you for your attention
