嘉立创庐山派 K230 Linux SDK LCD屏幕无法显示，只有背光亮

Question

问题描述

屏幕无任何显示，背光亮起，无异常报告。
硬件：嘉立创庐山派 K230 + 3.1寸LCD屏幕扩展板 + 嘉立创调焦摄像头
固件：CanMV-K230_LCKFB_linux_v0.6.9_nncase_v2.10.0.img
复现:
1、上电启动开发板
2、将linux主机中的./output/k230_canmv_lckfb_defconfig/target/usr/bin/v4l2-drm拷贝到k230中。
3、执行v4l2-drm -d 1 -w 480 -h 800。

按d的话可以正确保存图片，只是无法显示在屏幕上
还尝试了其他的方法显示屏幕，均以失败告终
v4l2-drm -d 1 -w 480 -h 800执行log如下
