Hi,

 

  我用的是BF518,我现在把SPI flash由以前的M25P16换成了AT45DB321,现在用VDSP++工具能连接到目标板,但是无法向里面写入u-boot,只有M25P16的driver,怎么办呢?

 

thanks!

你可以先从para flash里启动u-boot,然后在u-boot里写spi flash.

怎么实现从parallel flash启动u-boot呢?是要改变SW1的BOOT MODE 是吧?可是在我们自己设计的板子没有设计像评估板那样的boot模式,我们直接把它设计成了MODE 3模式,直接boot到SPI flash,有没有其它什么好的办法来解决这个问题呢?

Hi,Yi,

 

    怎么把u-boot到parallel flash呢?

 

    用VDSP++工具把driver选择parallel,然后program直接烧写行吗?
