我已经在rv1106-luckfox-pico-pro-max-ipc.dtsi修改earlycon=uart8250,mmio32,0xff4c0000 console=ttyFIQ0 root=/dev/mmcblk1p7 rootwait snd_soc_core.prealloc_buffer_size_kbytes=16 coherent_pool=0
为
earlycon=uart8250,mmio32,0xff4c0000 console=ttyFIQ0 console=tty0 root=/dev/mmcblk1p7 rootwait snd_soc_core.prealloc_buffer_size_kbytes=16 coherent_pool=0
此时启动信息可以输出到屏幕，但只能在屏幕下方大概三分之一处显示，已经测试屏幕无问题，请求解决
关于将启动信息输入到屏幕
关于这个你需要修改下内核文件把 luckfox-pico/sysdrv/source/kernel/drivers/video/fbdev/core/fbcon.c 中的#define SHOW_CENTER 1 修改为 #define SHOW_CENTER 0。因为我们默认全系列是用同一个内核的，ultra 系列为了让LOGO居中直接在内核上修改，LOGO的宽度超过屏幕的水平分辨率就不会显示，看起来就像在下方三分之一处显示。pan wrote: ↑2024-10-11 15:31 我已经在rv1106-luckfox-pico-pro-max-ipc.dtsi修改earlycon=uart8250,mmio32,0xff4c0000 console=ttyFIQ0 root=/dev/mmcblk1p7 rootwait snd_soc_core.prealloc_buffer_size_kbytes=16 coherent_pool=0

如果想启动内核时打印全部信息到LCD你首先需要修改内核设备树：rv1106-luckfox-pico-pro-max-ipc.dtsipan wrote: ↑2024-10-11 15:31 我已经在rv1106-luckfox-pico-pro-max-ipc.dtsi修改earlycon=uart8250,mmio32,0xff4c0000 console=ttyFIQ0 root=/dev/mmcblk1p7 rootwait snd_soc_core.prealloc_buffer_size_kbytes=16 coherent_pool=0
