全志客户服务平台
有获取流程的,你仔细找找.

your linux kernel crashed . maybe it is device tree issue idk.

@kelsey
全志官方的tina一般不这么玩，开源Linux(树莓派社区)一般用这种玩法.

@justyu666 在 T113 (tina) 如何编译打包spi nand flash 固件 中说：

@jr_online 亲，我按照您的分区表改后仍然无法打包，是还要改哪里呢？分区表的 mbr size 改了 252，但是打包提示还是 16384，如下图

麻烦指导一下，谢谢！

指导算不上，我也是半吊子，你把我上面的分区表复制替换你的分区表试试，总觉得是你的name = boot-resour有问题？不应该是boot-resource咩？不知道跟这个有没有关系

@xiaowenge 感谢指导👍 uboot里也有驱动，调用pwm驱动的接口就实现了

参考: d1-tina-linux-emac-开发指南.pdf

左边是非安全固件启动日志，右边是安全固件启动日志．

这篇文章记录了在wsl系统下编译调试awboot和linux的全过程

硬件要求：任意T113-S3芯片的板子，SPI0接spinand标准接法。

1、准备wsl开发环境

首先在win10或win11下安装wsl，选择wsl1或者wsl2都可以，wsl2的性能更高一些，wsl1的跨系统文件操作速度更快一些，我这里因为有一些工程在win文件系统下，所以选择了wsl1，发行版使用最新的Ubuntu 22.04.01 LTS。
这里我没有选用vm虚拟机安装ubuntu开发的原因是虚拟机下的文件交互不够方便，特别是git和文件对比，有时在内核源码改了一些文件，使用win下的TortoiseGit工具就可以很方便的查看差异，提交变更。使用beyond compare也可很方便的比较各种文件文件夹的不同版本的差异。
21d39193-ed21-4a4f-ae6f-d6dec28b7a9f-image.png
在win资源管理器下可以直接查看wsl的linux根目录，右键可以直接执行各种操作，就像操作win文件一样

这里编译开发的核心软件只有一个，就是VS code，安装好后添加所需的插件。
串口调试工具使用MobaXterm

下载交叉编译器，这里使用arm官方最新的GCC 12.2
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz
下载后解压在wsl的主目录，在.bashrc中添加编译器路径

PATH="$PATH:/home/wsl/arm-none-linux-gnueabihf/bin"

2、编译awboot

意外发现有awboot能够代替uboot直接引导内核，体验了一下果断选择awboot，因为足够简洁，编译大小只有32k，和uboot接近1M的体量相比，简直是小而美，启动速度也比uboot快上不少，也能同时支持sd卡，spinand，spinorflash启动。
https://github.com/szemzoa/awboot

说起uboot不禁想起几年前路由器第三方固件盛行的时期，那时的路由器还没有很复杂的方案，第三方固件往往比官方固件更易用功能更丰富，买个普通路由器换颗flash，内存芯片刷个系统就能获得更丰富的功能体验，各种固件openwrt，Padavan，高格百花齐放，为了刷机方便，系统的uboot都要支持tftp，串口甚至web的文件传输接口，由此孕育而出了大名鼎鼎的Breed，仅仅为了更新固件更方便，不用spi flash编程器那么麻烦的烧写。而到了全志嵌入式这边，由于自带usb接口的BROM，使用sunxi-fel或者xfel烧写flash已足够方便，所以使用uboot更新固件的需求就不是那么大，况且全志的方案比路由器的方案定制性更高一些，没有通用的第三方固件可以刷，所以uboot的功能就完全成了摆设，让用户使用sunxi-fel更新固件都要比uboot更新固件更稳定更实用，消费者用户用不到，开发人员也不会去用，那uboot的1m大小，集成的各种usb，网络，屏幕驱动，环境变量，文件系统，设备树编辑等功能就显得格外多余。

15a4a48f-2147-485d-a424-e76bd042c293-image.png

awboot相比spl+uboot的区别就是少了一次跳转的过程，由BROM拉起的boot0拥有足足160kb的sram，足够编写执行引导kernel的代码，所以这何尝不是一种恰到好处。

下面是awboot的编译过程：
修改makefile中的CROSS_COMPILE编译器定义为arm-none-linux-gnueabihf，或者使用

make CROSS_COMPILE=arm-none-linux-gnueabihf
命令编译
如果不是git拉取的而是手动下载解压的源码，需要去除git编译目标，位于makefile line:49
出现DWORD重复定义的错误，删除lib\fatfs\integer.h中的DWORD定义
链接出现未定义函数__aeabi_unwind_cpp_pr0，makefile中添加编译选项CFLAGS += -lgcc_eh
链接出现未定义函数raise，在main.c中添加函数

int raise(void) { return 0; }

编译成功，出现awboot.bin等文件

3、写入spinand测试

接下来是烧写入硬件验证，我的板子焊接的是W25N01GV，这里使用xfel，因为支持写入spi-nand。
https://github.com/xboot/xfel

为什么不使用sd卡验证，因为烧写sd卡需要：
拔卡->插到电脑->dd命令写入->拔卡->插到板子上。
而写入spi-nand只需要：
按着boot键同时按复位键->xfel命令写入(可以飞线两个按键，复位键接到reset脚到地，boot键接到spi-cs脚到地)。
步骤大幅减少，同时没有拔插sd卡造成的触点磨损。同时因为使用的wsl系统，并不能很方便的使用dd命令写入sd卡。虽然wsl下也不能直接访问全志的usb设备，但是xfel有win的版本，wsl下可直接执行exe文件，所以只需要下载xfel-windows解压到wsl中，在.bashrc中添加命令别名

alias xfel='/home/wsl/xfel-windows-v1.2.9/xfel.exe'
即可在wsl中使用win版的xfel，就像linux中的xfel一模一样。

make spi-boot.img xfel version xfel spinand xfel spinand erase 0 0x8000000 xfel spinand write 0 spi-boot.img

复位重启，可以在串口看到awboot打印的信息
awboot默认使用uart5打印，其他串口可以修改board.c中的配置，非常通俗易懂
内核加载地址如下表，可在board.h中修改

spi-nand内存划分 起始地址 空间容量 awboot 0 0x40000(256k) dtb 0x40000 0x40000(256k) kernel 0x80000 任意 [I] AWBoot r6143 starting... [I] SPI-NAND: W25N01GV detected [E] SPI-NAND: DTB verification failed [F] SPI-NAND: loading failed restarting...

4、编译kernel

接下来编译kernel，编译过程可能会出现缺少命令的报错，大概是下面这几个

sudo apt update sudo apt install flex bison bc libncurses-dev

目前linux主线的最新版本并没有适配t113的相关外设驱动，虽然能启动并串口打印，但其他的一些外设并没有驱动，还不是可用的状态，所以这里选择全志D1的kernel进行修改。
https://github.com/smaeul/linux/tree/d1/all

unzip linux-d1-all.zip cd linux-d1-all

应用awboot提供的linux补丁

linux/allow_select_d1_ccu_on_t113.patch linux/ccu-sun20i-make_cpux_clk_critical_for_t113.patch linux/second_core_support_in_platsmp.patch linux/d1s_t113_can_bus.patch

在arch\arm\configs\sunxi_defconfig中添加D1时钟

CONFIG_SUN20I_D1_CCU=y CONFIG_SUN20I_D1_R_CCU=y

添加sun8i-t113.dtsi和sun8i-t113-mangopi-dual.dts设备树配置文件到arch\arm\boot\dts
在arch\arm\boot\dts\Makefile的line:1389 处，CONFIG_MACH_SUN8I配置中添加sun8i-t113-mangopi-dual.dtb

awboot提供的sun8i-t113-mangopi-dual.dts设备树文件调试终端串口是5，需要改成uart0。

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- sunxi_defconfig make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- zImage -j4 make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- dtbs xfel spinand write 0x40000 arch/arm/boot/dts/sun8i-t113-mangopi-dual.dtb xfel spinand write 0x80000 arch/arm/boot/zImage

5245787f-02fb-49ac-ba26-e4167ce500f2-image.png

复位，串口成功打印内核信息，目前spinand中还没有文件系统，所以系统无法启动成功。

5、构建ubi文件系统

接下来是构建文件系统，这里使用最新的buildroot
https://buildroot.org/downloads/buildroot-2022.11.tar.gz

tar xf buildroot-2022.11.tar.gz
cd buildroot-2022.11
make menuconfig
配置目标指令集类型
006b7cd7-d0d3-40a7-b20b-b58a0ae89aca-image.png

配置外部自定义编译器
345e868b-a6ef-4376-9f7b-d01239c4aa36-image.png

配置生成文件系统类型为ubifs，最大逻辑擦除块数量决定了spinand的容量，我这里是128M的spinand，所以128M/128k = 1024
c798468b-ad46-44ea-b24a-bbe272779220-image.png

上面的这些配置操作可以用下面的默认配置文件代替，在configs文件夹创建sunxi_t113_spinand_defconfig文件，添加下面内容，使用make sunxi_t113_spinand_defconfig载入配置。

# architecture BR2_arm=y BR2_cortex_a7=y BR2_ARM_FPU_VFPV4=y # Toolchain BR2_TOOLCHAIN_EXTERNAL=y BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y BR2_TOOLCHAIN_EXTERNAL_PATH="/home/wsl/arm-none-linux-gnueabihf" BR2_TOOLCHAIN_EXTERNAL_GLIBC=y BR2_TOOLCHAIN_EXTERNAL_PREFIX="arm-none-linux-gnueabihf" BR2_TOOLCHAIN_EXTERNAL_CUSTOM_PREFIX="arm-none-linux-gnueabihf" BR2_TOOLCHAIN_EXTERNAL_GCC_12=y BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_20=y BR2_TOOLCHAIN_EXTERNAL_CUSTOM_GLIBC=y # BR2_TOOLCHAIN_EXTERNAL_INET_RPC is not set BR2_TOOLCHAIN_EXTERNAL_CXX=y # system # kernel # bootloader # filesystem / image BR2_TARGET_ROOTFS_UBI=y BR2_TARGET_ROOTFS_UBI_PEBSIZE=0x20000 BR2_TARGET_ROOTFS_UBI_SUBSIZE=0 BR2_TARGET_ROOTFS_UBIFS=y BR2_TARGET_ROOTFS_UBIFS_LEBSIZE=0x1f000 BR2_TARGET_ROOTFS_UBIFS_MINIOSIZE=0x800 BR2_TARGET_ROOTFS_UBIFS_MAXLEBCNT=1024 BR2_TARGET_ROOTFS_UBIFS_OPTS="-F"

配置完成后make开始编译，接下来就是漫长的下载编译过程，大概需要半小时。
编译成功后会生成output/images/rootfs.ubi，使用xfel命令写入。

xfel spinand erase 0x800000 0x7800000
xfel spinand write 0x800000 output/images/rootfs.ubi
复位发现没有启动成功，原来内核默认没有打开mtd和ubi支持，在内核配置添加下面选项

Device Drivers -> Memory Technology Device (MTD) support -> NAND -> SPI NAND device Support
Device Drivers -> Memory Technology Device (MTD) support -> Enable UBI - Unsorted block images
File Systems -> Miscellaneous filesystems -> UBIFS file system support
或者在arch\arm\configs\sunxi_defconfig中添加

CONFIG_MTD=y
CONFIG_MTD_SPI_NAND=y
CONFIG_MTD_UBI=y
CONFIG_UBIFS_FS=y
后重新载入配置。

另外设备树中的启动参数和分区也需要修改

bootargs = "mem=128M ubi.mtd=3 rootfstype=ubifs root=ubi0:rootfs rw rootwait console=ttyS0,115200"; &spi0 { pinctrl-0 = <&spi0_pins>; pinctrl-names = "default"; status = "okay"; spi_nand: spi_nand@0 { #address-cells = <1>; #size-cells = <1>; compatible = "spi-nand"; reg = <0>; partition@0 { label = "awboot"; reg = <0x0 0x40000>; /* 256K */ read-only; }; partition@40000 { label = "dtb"; reg = <0x40000 0x40000>; /* 256k */ read-only; }; partition@80000 { label = "kernel"; reg = <0x80000 0x780000>; /* 7.5MB */ read-only; }; partition@800000 { label = "rootfs"; reg = <0x800000 0x7800000>; }; }; };

修改完后重新写入spi-nand，系统顺利启动，一个标准linux 6.1的基础busybox文件系统就做好了，可以根据不同应用可在buildroot添加所需的命令，下面是我常用的一些命令，总之非常方便。

make menuconfig System configuration ---> [*] Enable root login with password Target packages ---> Networking applications ---> dropbear Target packages ---> Libraries ---> Hardware handling ---> tslib Target packages ---> Text editors and viewers ---> nano Target packages ---> System tools ---> htop iperf3 coremark dhrystone make busybox-menuconfig Archival Utilities ---> Make tar xxx, Autodetect compressed tarballs Linux System Utilities ---> Support mounting CIFS/SMB file systems Networking Utilities ---> httpd Networking Utilities ---> ntpd Networking Utilities ---> udhcpd Process Utilities ---> Support thread display in ps/pstree/top Process Utilities ---> pgrep Process Utilities ---> pmap Process Utilities ---> Show the number of users

只能打开修改安卓的固件，Linux固件不支持．

@jinxiangwzh
其他不清楚，没有用过V536．

@kelsey 大哥 你也阳了吗？还盼望着你的回复呢。

@lipeitong 您好 请问这个问题您解决了吗？ 是双目GC2053是吧？

@yuzukitsuru 全志

看看log，确认一下有没有烧进去，以及烧到哪个存储介质去了

@jinxiangwzh 没有这个测试项

@whycan 可以了，感谢指点

@whycan 不是 换了，固件配置是不是需要修改？

@whycan 已加

@yixiuge buildroot是个啥

官方例程lv_example_meter_3.c的钟表里指针采用的是贴图方式, 所以解决思路有两个:

针对屏幕分辨率, 优化贴图文件(img_hand.c)的样式 将贴图指针换成普通线段(粗细可调), 只要比的刻度粗一丁点或者把刻度覆盖掉就舒服多了.

贴出第二种方法变动:(基于lv_port_linux_frame_buffer.git)

--- a/examples/widgets/meter/lv_example_meter_3.c +++ b/examples/widgets/meter/lv_example_meter_3.c @@ -32,8 +32,9 @@ void lv_example_meter_3(void) LV_IMG_DECLARE(img_hand) /*Add a the hands from images*/ - lv_meter_indicator_t * indic_min = lv_meter_add_needle_img(meter, scale_min, &img_hand, 5, 5); - lv_meter_indicator_t * indic_hour = lv_meter_add_needle_img(meter, scale_min, &img_hand, 5, 5); + lv_meter_indicator_t * indic_min = lv_meter_add_needle_line(meter, scale_min, 5, lv_color_black(), 5); + lv_meter_indicator_t * indic_hour = lv_meter_add_needle_line(meter, scale_min, 3, lv_color_black(), 5);

效果:

@yuzukitsuru 请问我也碰到了这个问题，改了，还是这个错误，请问大佬有没有可以解决的方法
d368f43f-f991-4b69-92a3-d965bcd10af5-image.png

是的，git + repo + gerrit都有上
还有一些列的代码检测、编译检测、实体BSP烧写检测等工具

@whycan 嗯，也是个办法。
我最后是在一个低版本的win10虚拟机里搞的。

@q1215200171
这样修改后，发现cpu电压对了，但是CPU的启动频率还是没变，是哪里有问题？？？

@mengxp 看了下r328上使用的v3代码，关键字alloc，我发现有

ss_rng_start buf 内存泄露 (kmalloc without kfree)

目前就发现这一个

@q2022 不能用一张图片，uboot里头，用旋转前的，然后kernel加载旋转后的，不然切fb必然引起这个问题。我已经实现了，就是这样改的

@kiyan10 请问你这个问题怎么解决的？

我是直接用tf卡刷的固件，插到开发板的

@whycan
找到可以可以使用 rgb模式控制lcd，文档没看全，多谢多谢

@cube_work 可以修改 usb转串口驱动，把FTDI232的串口号改成其他的

@ceoifung

lcd_dclk_freq = <38>;
lcd_x = <720>;
lcd_y = <800>;

lcd_hbp = <52>;
lcd_ht = <774>;
lcd_hspw = <32>;
lcd_vbp = <16>;
lcd_vt = <828>;
lcd_vspw = <4>;

不行的话，lcd_ht以2为挡位慢慢网上加试试

@ceoifung 参考这样的配置：ctp_wakeup = <&pio PD 22 1 0xffffffff 0xffffffff 1>;
