TMS570LC4357: emac driver not work

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

I blocked by emac driver on LC4357 develop board,  It seems has no emac driver.

I gererate emac & system driver with HALCoGen 04.07.01, then do some modification according to LC3137 driver ,

it failed to make the emac work, 

when write data to 0xfc520140  :0x00000000 0x08009A82 0x0000003C 0xE000003C  the owner bit still 1,  seems data not been transfered

MDIO_USERACCESS0   202178C9

MDIO_LINK                    00000002

the RX isr  also can't been reached though it been registered in irq79,  I check the HL_sys_start.c, the emac related part same as LC3137 code which running well.  but the LC4357 can't got rx interrupt.

Could help on this or tell where to download a existing LC4357 emac driver to check if my develop board emac  working?

thanks!
