v3s串口2作为调试口,uboot正常,但卡在start kernel这里。

v3s,uart2作为调试口,使用w25q128作为存储。
参考论坛教程,修改后可以从spi flash启动uboot,也可以从uart2输出调试信息。
编译内核后,将设备树和内核烧录到spi flash,结果一直卡在start kernel这里,也不确定是不是内核这里设置串口2输出是否正常。

Re: v3s串口2作为调试口,uboot正常,但卡在start kernel这里。

问题已解决,spiflash规划时,给kernel规划了4M空间,实际上编译的kernel达到了5M。
去掉net组件及ext4支持,编译得到3.3M左右。
后来群友提示,可以使用xz压缩,发现默认使用的是gzip压缩,使用xz压缩的话,不作裁减,编译得到3.4M。但是uboot里没找到xz解压所的支持。于是选了lzap,编译后内核大小是3.7M左右。
