Есть самодельная плата с Artix 7 и DP83867E.
По MII задаю и читаю следующие регистры
1. CTRL(h001F) <--- h8000, читаю 0. сброс с регистрами
2. BMCR(h0) <-- h0140 , опрашиваю =h0140. задал 1000BASE
3. PHYCR (h0010) <--- hf068 . dis SGMII опрос= hf068
4. CFG1 (h0009) <--- h1b00 (или h0300), опрос= h1b00 . показать способность.
5. CFG3 (h001E) <--- hcb02 , опрос= hcb02 .
6. BISCR(h0016) <--- h0. но здесь задавал digital loopback - все работает т.е. данные возвращаются.
7. RGMIICTL(h0032) <--- h00d3 , опрос= h00d3 , RGMII ENABLE.
8. RGMIIDCTL
9. CTRL (h001f) <--- h4000 soft restart.
далее я читаю BMSR(h0001), PHYSTS(H0011), STS2(h0017) - все нормально.
но читаю STS1 (h000A) и получаю h4000. h0 получал при других значениях.
еще попробовал analog loopback - все работает т.е. данные возвращаются.
и связаться с компьютером не могу.
что не так?
