平台环境

• 板子：OK536N-C开发板
• 编译环境：wsl2-ubuntu22.04

获取并解压sdk

cat OKT536-linux-sdk.tar.bz2.* > OKT536-linux-sdk.tar.bz2
tar -xjvf OKT536-linux-sdk.tar.bz2
cd OKT536-linux-sdk

配置sdk

./build.sh config
linux-->
buildroot-->
t536-->
OKT536-C-->
default-->
linux-5.10-origin

编译SDK

配置环境变量

source build/envsetup.sh

报错：ERROR: Please source envsetup.sh in the root of SDK
解决方案：
创建.tinatopdir

touch build/.tinatopdir

再次运行，完成环境变量配置

source build/envsetup.sh

开始编译：

./build.sh

rtos编译路径依赖报错，
解决方案：

crtos
rm build -rf
croot
source build/envsetup.sh
./build.sh

继续编译报：QQuickItemsModule::defineModule未定义错误
解决方案：

rm -rf /home/dzh/work/t536/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/build/qt5declarative-1d49a5b678957adde7e2db23a485a3f48157bc8f

继续编译

报错：qt-demo编译报错

解决方案：

cd ./buildroot/package/auto/forlinx/qt_demo
mv Makefile ../
rm -rfv $(find ./ -name Makefile)
mv ../Makefile ./
croot
./build.sh

最终编译通过：

打包固件：

./build.sh pack

请问一下各位大佬：

1. T507目前SDK好像还是Linux4.9内核，最近有无升级内核版本的规划，向tina6.0看齐?；
2. 请问一下T536是否适配好tina6.0;

@duanzhh u-boot.map部分的symbol

1、想基于A40i平台移植双核系统，需要进入hyp虚拟机模式
2、全志自己定制的uboot引导内核时是基于svc方式进行引导的
3、自己仿照主线开源部分改动了一点代码，如下所示，但是，一直会卡死，，，没思路了
4、有大佬帮忙指导一下思路方向吗

@hyezzz 请问楼主解决了吗，如何改为hyp模式的

@awwwwa 嗯嗯，好的，感谢大佬！

@awwwwa 您好，是通过代理商获取的，目前使用的版本是基于buildroot修改的版本：auto-t113-linux-V1.1 release

请问这是最新的商业版本吗

@duanzhh 也有可能官方硬件驱动需要再优化一下，这样发生仲裁丢失的概率就会少一些

@xiaowenge 跟踪到最后发现是arbitration lost interrupt报错 ：

晓得了，硬件仲裁机制导致的

有大佬提提建议吗，不知道从哪下手了。。。

1、配置can0设备树
2、编译烧录固件，设置波特率为1M
3、建立can通信，2ms周期，can总线带宽占用40%左右
4、使用ifconfig can0查看状态，发现can0的tx出现很多发送错误包（应该是链路层上报错，上层协议层没有报错），见图片：

@awwwwa 好的，大佬，感谢

@awwwwa 嗯嗯，感谢，使用can发现一个问题，发送错误码太高了，波特率是1M，总线带宽30%左右，

感觉不应该有这么高的错误率

@awwwwa 好的，感谢大佬

@awwwwa 好的，感谢大佬，还有一个疑问，像这外挂上的spc、ccu用户手册内都没有介绍时钟如何配置，这种更改必须要找原厂帮忙吗

请问下T113串口波特率支持4.5M吗，稳定吗，有没有大佬告知下，想通过供APB1_CLK为75M，分频到4.5M波特率，不知道本身芯片支不支持，用来做商业化产品

@evler 大佬你好哈！我拉了你的https://github.com/Evlers/linux_kernel_t113.git然后使用mangopi_dual_t113_defconfig配置文件，设备树中加了uart3配置；启动方式使用：uboot + linux6.0.1+buildroot rootfs；但是出现了奇怪的现象：CPU1: failed to come online cpu1启动失败； 请教大佬有什么什么思路提供？十分感谢 启动log如下：

与主线linux内核启动log对比：

大佬 ，yyds

@masterlu 我也遇到了，有解决办法吗

平台：r818
系统：tina- linux4.9
rootfs：ubuntu18 + xfce4 + slim

问题描述：linux设备树，更改显示格式：

fb0_format               = <0>;  

烧录固件，启动登录系统：桌面背景黑色，弹出的字体发虚；但是xfce4-panel的字体是正常的，打开浏览器的字体和背景也是正常的；

我有尝试改变xfce4外观，但好像只是改变主题的，这种不清楚啥原因的。有大佬遇见过这种现象吗？

@yuzukitsuru 感谢大佬，我想一下别的方法

@yuzukitsuru 感谢大佬指点，我同步开启的font选项，启动时还是会报错，换成模块加载的形式，进行终端加载就不会报错。应该就是大佬说的加载顺序问题。那如果基于现状，想把log信息放在lcd显示，有什么其他方法推荐的

有大佬遇见过类似现象吗

平台：r818
系统：tina

问题：想把log信息放在lcd上显示
对策：更改内核的menuconfig
现象：平台启动崩溃
请问有大佬遇到过吗，有没有什么思路提供的

@daizebin 我使用的时resize2fs这个指令调整文件系统分区大小的

@yuzukitsuru 感谢大佬 ，昨天按照你的指示检查了一下，rootfs.img确实有问题，需要额外加一句调整分区的指令才可以；后面得空再研究如何使用overlayfs，特别感谢

环境：
emmc：8G
平台：r818
系统：tina + ubuntu

现象描述：
当挂载的rootfs.img小于4G时，系统可以正常启动；当rootfs.img大于4G时，系统开机卡在挂载根文件系统系统阶段。

目前给的分区大小：

[partition]
    name         = rootfs
    size         = 10485760   # 5G大小
    downloadfile = "rootfs.fex"
    user_type    = 0x8000

打包rootfs.img为4.9G大小：

请问有人遇到过这种吗，大佬们有没有解决思路提供啊

@yixiuge 大佬你好哈！最近我也在搞AIC800上ubuntu18.04的xfce桌面，我发现必须要将显示引擎端的比如fb0_format设置为rgb565格式，xfce桌面才能正常显示，如果使用默认argb8888格式，xfce桌面显示黑屏。大佬，请教一下如果想设置成xfce桌面argb8888显示，该怎样操作啊

@yuzukitsuru 大佬这么晚还没睡觉，太辛苦了

uboot阶段显示正常，kernel阶段显示概率性不正常，有锯齿，系统ui端又是正常的，从de截屏看，在de阶段合成图片出了问题，请问这种有解决思路吗

不正常图片（从de截屏得到的）：

正常的图片：

有大佬帮忙分析下可能存在的原因吗

@duanzhh 找到原因了，mad，智障自己，流控打开又给自己在system_config.fex里面关闭了

@whycan 晕哥，我使用tina的sdk调试xr829蓝牙时，一直出现这种问题，Initialization timed out.，请教一下这种可以从哪些方面排查问题啊：
