关于dp83848cvv与dp83640tvv的区别

Other Parts Discussed in Thread: DP83640

查看了下,两款芯片的引脚是兼容的,我在stm32f429开发板上有一片dp83848,我把它换成dp83848cvv后,程序卡在一段软复位代码上。如下:

  (heth->Instance)->DMABMR |= ETH_DMABMR_SR;
 
  /* Wait for software reset */
  while (((heth->Instance)->DMABMR & ETH_DMABMR_SR) != (uint32_t)RESET)
  {
  }
 

我想知道,这两块芯片的驱动是一样的吗?存在哪些区别,是不是不能直接替换使用。谢谢。
