Hi,<br><br>I want to change one register inside the LXT971A:<br>set 0 the parameter PHY_LXT971_DIG_CFG_MII_DRIVE&nbsp; for the register  PHY_LXT971_TX_CTRL, this register is define in the file include/lxt971a.h ,&nbsp; so I&nbsp; think that I have need to change&nbsp; the file&nbsp; 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.<br>If you have any idea to modify just the parameter PHY_LXT971_DIG_CFG_MII_DRIVE ?<br>Thanks for your help.<br><br><br><p>&#32;
