大家好,我用的开发板是BF518F-EZBRD,以前的SPI flash为m25p16,现在把SPI flash换成了M25P32,u-boot从SPI 开始引导,修改之后用VDSP++向里面能写入u-boot,显示写入成功,但是重新上电之后就不能运行u-boot了,什么反应都没有,是因为u-boot里面要修改什么东西吗?

 

u-boot和SPI flash的大小有没有关系?谢谢!

the size of the SPI flash does not matter.  u-boot is at the start of the flash and it detects the part automatically at runtime.
