This is a known issue. The problem is that the AM335X nRESET_INOUT (or warm reset) is released at approximately the moment that the PHY latches internally it's bootstrap resistors. Once in a while this happens too soon and the PHY doesn't come out of reset correctly. *This can be avoided if the PHY reset is tied to a processor GPIO (it's important that the GPIO stays in low state during reset and at reset release time).* SO this can be fix by hardware modification. But I'm not an expert ... I'm just reading what Texas replied to this. http://e2e.ti.com/support/arm/sitara_arm/f/791/t/347189 Le Tue Dec 16 2014 at 10:04:04, <[email protected]> a écrit : > Micka, > > I guess Michrochip is responsible for this problem, because their chip > LAN8710A often doesn't start in a right way, in spite of correct > strappings.
