.rodata' can not be used when making a PIE object; recompile with -fPIE

连接时报错，应该不是缺库

剩下还挺多的

我的图。
一定是有问题。 解决方法步骤：
1、找到LCD 的资料，对比引脚。这个屏幕型号资料 网上找不到。
2、LCD 背部有一个转接板，转接板改变信号走向。

最后没办法更换的其它5寸LCD 800x480 。

@whycan 启动的是 SBOOT 而不是 BOOT0 （
（以及龙脸的那个报错

@secnal 在 订单号1602537027102107792的开发工具包 中说：

@xiaowenge 谢谢，就是官方套餐里的，目前还没找到😬

是指实物的开发工具包吗？数据线串口线？

我换了好多几个环境拷贝 整个sdk 都能重现了这个问题。
尝试make -d发现连cp这样基础的方法都出现找不到LIBC 2.XX等问题，这让我意识到这不完全是与操作系统相关的问题。
搜索cp发现out/host目录下有着一套独立的用于编译的系统环境。
然后果断

cd out mv host ../.. rm -rf ./*

正在编译中..., 没有再报错了。

@yteraa 在 Tina linux 如何更改system init 中说：

busybox init 需要配置一些选项和 busybox-int-base-files这些东西

主要做这些修改

👍👍 👍 👍

@yteraa 加密还是得用 SSK

ts_calibrate
ts_test
有没有反应

换 VirtualBox（不是

1.大佬是用什么sdk的呀？我用的是韦东山提供的buildroot工程neza-d1-buildroot，
2.然后感觉那个uboot有点问题，不会遍历dts中第二层级的device，我在源码上参照那个clocks的来遍历第二层，第三层的device，在uboot 输入dm tree可以正常显示device对应的层级关系。只是第三层级的spinor没有绑定成功

@soso90 播放前打开音频通路

@whycan 晕哥，请问一下，uboot的命令行中没有load这个命令，加载不了mmc的内容。怎么办？

@wanglang
可能不是每一个package都验证过, 楼主你试一试找一下文件：
find . -name cdx_log.h

然后复制到对应目录，手动修复编译错误．

现在uboot部分都没有进入到LCD_open_flow 这个函数中，对比了驱动文件和设备树的名字也是一一致的：

@whycan 刚开始贴的log打印，应该是程序的一些空指针的操作导致系统挂了

一顿操作猛如虎, 终于搞定MIPI LCD

请问如何编译decodertest呢？

make menuconfig *** <*>decodertest

执行编译
后报错

decodertest.c:13:21: fatal error: cdx_log.h: No such file or directory #include <cdx_log.h> ^ compilation terminated. make[3]: *** [decodertest.o] Error 1

=======================

这个得去看c906的手册

xfel

用 MSVC2017 编译 XFEL 项目

由于部分软件包中的源码位于另外的仓库目录下，因此，在修改源码后，openwrt 无法知道源码已经更新需要重新编译此软件包

可以用下面这个命令强制删除老源码重新编译这个包

mmo lv_examples -B

@cube_work 只要kernel的驱动不挂，刷新IAL就能识别

下单了1片

不过感觉还是紫色好看啊！

@whycan

感谢感谢，终于搞定了！👍

就是配好 CONFIG_EFI_PARTITION

@apollo5520 测不到信号就不是这个问题了，加载驱动的时候默认会打开dxco。我那个问题是信号噪音过大的问题

@jacky502 ，我U盘读写都是可以的，你出错的时候是什么提示？

@wanglang busybox ls -la

@shz18877605430 晕哥，不是说要更改uboot得.config吗？但是我没找到改分辨率得地方，现在还是用480*272得分辨率，uboot往内核传参的地方没找到。

@huangkun 在 求教搭载全志t7的车机内存扩容问题 中说：

@yteraa

非常感谢, 学习了.

F1c手册中 vcc-core：1.0~1.2V。tiny200板子直接给了1.2V，很鸡血。反正芯片不会有多少温度

分析到了。上下电时序可能有异常，破坏了efuse中rotpk的某些比特。

正确的rotpk
74e61bc6f59b1382a29019xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

芯片中的rotpk
74e61bc6fd9b1382a39019xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

果然efuse供电引脚需要改成按需上电。

单个kmalloc一般最大4MB，过大换vmalloc比较好

@yuzukitsuru
谢谢大佬，正是我要的．

@mengxp
不能这么说，刚好S3/R11 没有引出这个腿而已，
F1C有几组MCLK复用，但是只有一个MCLK引脚。

@shz18877605430

我已经三次提到 ts_uinput 了，您怎么不试一试呢？

这个解决方案是最简单的了。

只改 kernel 和 mount 参数，看来还是不行，一定得对busybox动手？

@tevet 在 为了摆脱TINA-BSP的磁盘噩梦能舒服地只编译LVGL8在D1S/D1上面肆意玩耍 中说：

@jr_online 显然你的T113的环境依赖文件要拿出来的，
还是要载一下BSP来 拿出staging 编译出来的那些库呀，不然怎么能拿到正确的依赖库呢。
有空再给你搞搞咯

好的，感谢大佬[抱拳]😁 😁 😁

@yuzukitsuru 怎么换？？请指教。

@yuzukitsuru 后续这个屏几个测试指令不太对，大佬有啥改进思路吗

@yuzukitsuru 收到，多谢

@liuxingkeji 主要是资料不太对

@yuzukitsuru @tigger 大佬你们点亮了吗？

@mangogeek 华秋太草了

@efancier ，更新下状态，确定是１.５V，电流要求不高，８０ｍＡ　可以驱动，启动的时候对纹波要求比较高，用一个１０uF的电容压住就可以了。

请问楼主，最后板子做出来了吗？

@rcfly 能否分享下你的XR829驱动呢，目前我移植的老是发现cmd53接收不到东西

@whycan 在 配置好config之后重新编译，lvgl还是没有显示，屏幕上一直是原来的哪吒图片 中说：

@jr_online
buildroot busybox 文件系统可以放/etc/init.d/ 或 /etc/profile.d/

大佬，新手的我还不太懂buildroot busybox 文件系统这些😥 ，我现在是基于一个t113的tina sdk，在tina-t113/target/allwinner/t113-mq/base-files/etc/目录下新建了一个目录init.d，里面弄了一个脚本lvgldemo，但是编译成固件到板子上没效果。虽然这应该是不对的做法，忽略了一些东西，但是想着快速入门，就模仿着弄了。😵

@whycan 大佬，哪里有的卖?

@q1215200171 就是按照这个 faq 里的说明操作的，但是没有效果。

原来是sys_partition.fex中，把rootfs.fex的分区大小定义为了1G，所以哪怕编译出来的rootfs.fex才不到200MB，用烧写工具烧写的时候，还是会出现ext4的1G的分区。改这个文件就对啦，现在改成了320M，需要使用到的扇区数是655360, 320M = 512*655360
partition.png
修改后，烧写进SD卡的文件系统用dg看，可以发现已经从1G到320MB了
partition1.png
还要注意改了后，要重新擦除下SD卡，再烧写，不然分区信息不会变，之前我还以为自己修改后的没生效

@anruliu 在 t113 gt11触摸驱动 打包报错 中说：

@jr_online 确认下内核有没有配置CONFIG_INPUT_SENSORINIT

感谢大佬，就是这个CONFIG_INPUT_SENSORINIT没有配置，非常感谢提点！

@honey130602 内存分配机制出问题导致，选错了

@tigger 最近才确认清楚，是频偏问题导致
