F1C100S使用主线uboot如何更改默认终端串口

默认是UART0 PE0 PE1
想改到到UART1 PA2 PA3






我看了坑网的zero改串口，别人问这个问题的时候，晕哥也是让看zero的，
但是我改了设备树里的pinctr复用，chose，各种东西。
但是spl还是uart0打印，而uart1里没有任何数据。
无从下手，改了好多遍

之前花了一点时间改了一下,希望帮得上忙

Re: F1C100S使用主线uboot如何更改默认终端串口

这个文件 include/configs/suniv.h 还得加上:

#define CONFIG_CONS_INDEX       1  //UART0
#define CONFIG_CONS_INDEX       2  //UART1
#define CONFIG_CONS_INDEX       3  //UART2

#define CONFIG_CONS_INDEX       1  //UART0

改这个只能影响u-boot 的 spl 串口输出， 如果u-boot输出还得改 dts 文件:

Re: F1C100S使用主线uboot如何更改默认终端串口

U-BOOT改好了，参数好像会直接传递到内核，所以内核那边是不需要去改的。只停在start kernel可能是原来传递的是ttyS0，你没改到ttyS1.

能分享下教程么？我想我串口2打印日志，BSP LINUX3.10 修改fex文件和uboot都不好使，现在想用主线UBOOT引导BSP来实现，但是不知道怎么实现
