v3s licheepi 调试u-boot和kernel卡住了
主要有以下3个疑点：
1、日志中出现 [ 0.130002] console [ttyS0] disabled 是否有影响
2、日志中出现 [ 0.932730] m25p80 spi32766.0: unrecognized JEDEC id bytes: 0b, 40, 18
[ 0.939382] m25p80: probe of spi32766.0 failed with error -2
怎么解决？
3、日志到了[ 1.537083] Console: switching to colour dummy device 80x30就不再走下去了
