Set lan speed with 10M problem

Question

I have download the sample code from official Library and Peripheral Example. I want to set lan speed with 10M problem with set_link function in W7500x_miim.c but it have not update control register and also is 100M. I read the PHYREG_CONTROL is not equal to I wrote. I have reference wizwiki.net/wiki/lib/exe/fetch.p … erence.pdf but can not solve problem. Any one have same problem? have any suggestion to me?

I use mdio_write to change the speed: mdio_write(GPIOB, 0, 0x0100); // 10MBs full duplex Also be sure the mii link is correct!! phy_id does a check if return data is not 0, but forgets to check if data == 0xFFFF For me this solved a lot of problems. int32_t phy_id(void) { ...... All settings in miim.c printf("PHY_ID = %d , STATUS = %x",i,data); //Should be someting like: 0x7869 if(data != 0 && data != 0xFFFF) return i; // !!!! Check if data isn't all 1's! } printf("[PHY]:ID detect error!!
"); } return 0; }
