我手头没有5272的spec,粗看了一下5271的 during this time the contents of the mmfr register will be altered as the contents are serially shifted, and will be unpredictable if read by the user. once the read management frame operation has completed, the mii interrupt will be generated. at this time the contents of the mmfr register will match the original value written except for the data field whose contents have been replaced by the value read from the phy register. 所以你在那时读mmfr的寄存器,应该是不能说明什么的。 我也有个疑问,为什么在你的板子供应商提供的bsp里没有 fec的缺省驱动呢? 我想对于uclinux里的fec应该是很早就支持的吧 | | |
