V3S现在升级成V3LP了吗?

有图有资料吗

吴助建说：

八成是RS-232芯片支持不到460800 bps。
要么换RS-232芯片，要么换周围的0.1uF电容到1uF或10uF试试。
跟软件应该没什么关系。

已解决，串口驱动的时钟配置问题

补充信息

how0723 · 全志 SOC

T113-S3串口UART0 接收错误，波特率115200时正常，波特率460800时错误

串口错误标志位解读：
FE：帧错误，指示当前字符是否存在帧错误(缺少停止位)并且可能已经损坏
BRK:BREAK检测，指示当前字符是否为BREAK字符，数据位和停止位均为0
OE：接收器超限，指示接收过程中，是否存在数据来不及接收的现象
PRERR：RS-485模式下，它保存接收到的9位RS-485数据的第9个数据位。在RS-232/IrDA模式下，它是奇偶校验错误标志。指示是否检测到当前字符是否具有奇偶校验错误并且可能已经损坏
Error Detect:错误检测，指示RX_DATA字段是否具有错误-OE FE BRK PRERR

测出来的波形，黄色是RS232 绿色是TTL

@hzy831225
修改内核源码这里是不是写错了啊？

how0723 · 全志 SOC

阿黄说：

结贴，需要在uboot中初始化LCD。原因还不明。暂时先这样了

请问如何在在uboot中初始化LCD ？

how0723 · 全志 SOC

@nuvoton
如果使用sun8i-v3s-licheepi-zero-dock.dts，就完全不能驱动屏幕

how0723 · 全志 SOC

@chenzh
按这个方法还是没有解决

how0723 · 全志 SOC

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
