楼主，您好，看了您的贴子，手头正好有一块stm32f746-disco 的板子，按照您的思路，移植了uboot2016.09，移植了uboot eth驱动，因为没有移植MMC驱动，就打算把linux内核加载在SDRAM上，再从SDRAM启动内核；使用的是linux4.19.24默认的stm32配置，但是现在一直卡在“Starting kernel ...”，内核应该是没有起来；不知道您调试过程中是否遇到这个问题。附上打印的信息：! t# Y m1 |8 P t

接下来看看kernel 咋能。
说下eth dma 最大的注意事项，就是cache dma ram 一致性， 卡了好个晚上，对于这个一致性，没有多少经验，希望大家给点经验指导下。

这个STM工程师比较那个，我也被坑了，各种分析，内存BUFF分析 等等 我就像骂一句 mmp& w5 ]5 b4 @/ F/ {5 h; t
谢楼主啊
楼主您好，linux内核确实是你说的那样，但是改了uboot的bootargs后，仍然不能在启动内核后打印信息。。。stm的工程师看来是只管写不管有没有用啊。。。
