boot 使用的是 https://gitee.com/LicheePiNano/lv7_rtthread_f1c100s 的spl
借鉴了一个keil 工程 和 https://whycan.com/t_1457.html 的 framebuffer
其中dede 初始化的时候 设置dede->mode 就崩溃了,很奇怪 可以读寄存器,但是不能写,写完程序就奔溃了,
如果屏蔽掉了就可以运行通过,但是可以显示,屏幕分辨率可以设置,但是显示的颜色不是设置buff的颜色,而是随机的 几个颜色重复出现,感觉buff的数据没设置进去
想咨询一下 移植过framebuffer的高手,处理按步骤初始化,还需要做什么额外处理吗 例如在启动文件添加某些东西?

额 话说 这就是我的gitee,里面的boot不完善,现在优化他 发现拷贝1.5M左右的应用需要3s的时间,SPI的频率调整50M还是100M感觉没区别,也不知道为什么uboot 下LINUX系统100多M 做么就10来秒就启动了,
现在想在BOOT显示图片 这样给人感觉系统里面就工作起来了

dede->mode 不能使能 是还有什么其他地方需要配置么?
离线
debe 不能使能 是不是因为内存没有分配的原因呢?
