Microblaze linux在“已禁用引导控制台[earlyser0]时停止引导”

我想在nexys 4 ddr板上嵌入linux。 我制作了一个基本系统：microblaze+ddr+uartlite+gpios Linux映像由build root 2014.05制作

禁用引导控制台[earlyser0]后Linux引导停止

发生了一些奇怪的事情：我把console=ttyUL0和BR2\u TARGET\u GENERIC\u GETTY\u PORT=ttyUL0放在一起，但是，启动时我看到40600000.serial.ttyUL1，有一些解释吗

不管怎样，在dts和defconfig中加入UL1都会得到相同的结果

我的dts

/dts-v1/;

请提供一些帮助

尝试编辑从引导程序传递到控制台=TTYUL1115200N8的内核的命令行，因为这是您唯一配置的串行端口，并且模式已完全指定。sawdust-感谢您的回答，我将命令行更改为console=TTYUL1115200N8，但没有任何更改
