@xh_timmo 问题解决了，就是多等等，多等等，就好了

@vincent1 我现在已经勾选上a665042e-926b-4470-b346-0fdd0d2e8733-image.png
并且在board.dts和uboot-board.dts中在disp中加上

disp_rotation_used = <1>; degree0 = <2>;

现在开机logo到kernel阶段时候已经旋转了180° 但是我的qt好像不能刷新屏幕了
我用

cat /dev/urandom > /dev/fb0

lcd屏也不会出现花屏 请问接下来要怎么办？？？

@y97788 在 ubifs卷挂载问题 中说：

ubiupdatevol /dev/ubi0_1 boot-resource.fex
这样可以修改整个卷的数据，但是如何修改boot-resource.fex里bootlogo.bmp，或者如何将新的bootlogo.bmp打包生成boot-resource.fex文件，然后再用上面命令来更新卷数据

你好，我也碰到了这个问题，请问你解决了吗

博主有没有移过8733BU usbwifi的 模组厂商给了驱动文件 我按这种方式来没作用 编不出来KO文件

您好，论坛的那个文章，最后一步要传哪些文件到开发板上？

@daizebin 在 DragonSN烧写PN后可以在哪里可以读出来？ 中说：

@hnjztyx private分区挂载上就可以了

博主这个怎么挂啊 我mount不行

@jingyan
有测过两块T507互发互收，都是用2M波特率，这样测试又是没有乱码。所以感觉理论上回环也是没有乱码的，跟PC端传输才有乱码。有空我再测一下回环。

@vc915813805 内核和uboot同时配就好了，显示logo要uboot那边就初始化屏幕

博主这个咋解决的啊

@story_xjj 请问解决了吗，我也遇到同样问题

@mysteryli
可以了 结贴

@fanhuacloud 我也遇到这个，以后执行ls -al就行了

已解决，是硬件spi设计问题。

@tjhohai1983 6b46dc82-6b93-43b0-9ac1-0841b07cd285-image.png

@cfxcfx
进入sunxi_gpadc.c文件中，删除以下代码中的 |BIT_MASK(EV_REP)

switch (id) { case GP_CH_0: #ifdef CONFIG_ARCH_SUN8IW18 case GP_CH_3: input_dev->evbit[0] = BIT_MASK(EV_KEY); #else input_dev->evbit[0] = BIT_MASK(EV_KEY)|BIT_MASK(EV_REP); #endif for (i = 0; i < KEY_MAX_CNT; i++) set_bit(sunxi_gpadc->scankeycodes[i], input_dev->keybit); break;

应该是，我去试验一下。

DragonSN 烧录的数据放置在Secure storage区域或者单独的private分区，这个要确定好；
通常都是在private区域，需要先烧好SN号之后，对应的分区才会被格式化为vfat文件系统，否则是挂载不上的

@asoul_ava 是个电源供电都加电容了。

@z15242116489 dts节点要放对应的i2c下面，你放dtsi是没法识别到设备的。
最新社区内核代码github有
https://github.com/torvalds/linux

已经实现了，这玩意估计要联系代理商另外花钱买，要收授权费的

@jingyan 感谢提示，现在解决了，是因为买的韦东山的扩展板，需要去掉几个电阻，链接 https://forums.100ask.net/t/topic/5550

Flutter t113能跑不~·

@daizebin 看起来和 mcu 调试一样

栈回溯显示spi传输超时了，看下是不是开启的配置导致IO被复用了，另外把你开启XR829的配置和改动也发上来看下

IMG_7074.jpeg 我放几秒就卡死求指点

@xzhang 在 TinyVision tina5.0编译问题 中说：

touch: setting times of '-': Permission denied

touch: setting times of '-': Permission denied

指的是使用makefile调用touch命令对目录"-"读写失败(没有权限)，touch会创建文件并更新文件的时间戳

你可以用 ls -alh 把目录下的权限列出并贴图上来让人帮你排查

@zifeiyu 可以看一下Linux常用的通用终端文件传输协议（modem系列协议，有Xmodem, Ymodem, Zmodem三种，Y兼具速度和兼容性），可以在串口和网口终端传输，如果你使用RS485，则受限于串口的速率。

@wd15365693548 不用，在uboot命令行改启动参数就可以

setenv initcall_debug 1 boot

@shz18877605430 报错是使用呢CSI 不是MIPI-CSIS

同问，有OTA需求

nanopi neo 用的是哪颗芯片？

H3

CKLINK JTAG仿真器。

@null037 谢谢佬，我自己在家用的虚拟机就是18.04，确实没有出现这些问题，编译运行很顺利。但是日常工作的电脑是20.04的系统，遇到这个问题也是想解决一下

@coder9527 新手向大佬学习👍 👍

mark 一下。

是否是两个屏幕，分别用独立的 LCD 控制器驱动？

@zhuhehui
今天又能下载了，估计是我升级到LV2的原因。昨天还是LV1呢。

bootcmd 和 boot args 可以在 uboot 中设置
[*] Enable boot arguments │ │

[*] Enable a default value for bootcmd │ │

这样编译后直接能启动

@fleieng 你用的不是PMIC？独立的DcDC那

各位大佬在用的时候没有发现内存泄漏吗？好像是mpv导致的，有没有解决办法啊

@miller370321 看源码呗

@awwwwa 那么Edison怎么烧录

有详细步骤么，我DVP摄像头调试不出来，找不到设备，摄像头用的是OV2640
