[U-Boot-Users] Ethernet: read/write register inside lxt972 with at91rm9200 processor

[edo01 edo01]

Hi,

I want to change one register inside the LXT971A:
set 0 the parameter PHY_LXT971_DIG_CFG_MII_DRIVE  for the register  PHY_LXT971_TX_CTRL, this register is define in the file include/lxt971a.h ,  so I  think that I have need to change  the file  cpu/at91rm9200/lxt972.c . I call the function at91rm9200_EmacWritePhy(p_mac, PHY_LXT971_TX_CTRL, 0) inside the function lxt972_InitPhy but without success, just no ethernet efter my modification.
If you have any idea to modify just the parameter PHY_LXT971_DIG_CFG_MII_DRIVE ?
Thanks for your help.
