一、awboot编译
排针版，有一个usb2ttl，默认是uart4
修改board.h

二、linux内核为evlers修改后的源码编译
设备树
1 、改alias
aliases {
ethernet0 = &rtl8189fs;
mmc0 = &mmc0;
serial1 = &uart1;
serial4 = &uart4;
serial5 = &uart5;
};
2、改内核启动参数
chosen {
stdout-path = "serial4:115200n8";
bootargs = "mem=128M cma=72M root=/dev/mmcblk0p3 rootfstype=ext4 init=/linuxrc rw rootwait console=tty0 console=ttyS4,115200";
};

3、改pio
uart4_pe4_pins: uart4-pe4-pins {
pins = "PE4", "PE5";
function = "uart4";
};
uart5_pb4_pins: uart5-pb4-pins {
pins = "PB4", "PB5";

buildroot：
buildroot-2022.02.5
改国内源
BR2_BACKUP_SITE="http://sources.buildroot.net"
BR2_KERNEL_MIRROR="https://mirror.bjtu.edu.cn/kernel/"
BR2_GNU_MIRROR="http://mirrors.nju.edu.cn/gnu/"
BR2_LUAROCKS_MIRROR="http://luarocks.cn"
BR2_CPAN_MIRROR="http://cpan.nju.edu.cn/CPAN/"
buildroot使用自编交叉编译器，linux的version.h版本最好跟主机的交叉编译器版本对上
BR2_DEFAULT_KERNEL_HEADERS="5.15.53"

awboot是用arm-none-eabi-gcc编译的依赖性弱。
linux内核调用主机本地交叉编译器和buildroot可以设定自编交叉编译器版本要对上。不然会导致稀奇古怪的问题，浪费时间。这个是linux头痛的问题。

sd卡分区：
mbr 3个区，
第一个区不用，引导用，brom会读取这个区引导awboot
第二个区fat32，内核以及dtb
第三个区ex4，buildroot

不想折腾的话，就装虚拟机。

• gpio的调试：

root@TinaLinux:/# cd /sys/class/gpio
root@TinaLinux:/sys/class/gpio# ls
export     gpiochip0  unexport
root@TinaLinux:/sys/class/gpio# echo 36 >export
root@TinaLinux:/sys/class/gpio# ls
export     gpio36     gpiochip0  unexport
root@TinaLinux:/sys/class/gpio# cd gpio36
root@TinaLinux:/sys/devices/platform/soc@3000000/2000000.pinctrl/gpiochip0/gpio/gpio36# ls
active_low            edge                  uevent
device                power                 value
direction             subsystem             waiting_for_supplier
root@TinaLinux:/sys/devices/platform/soc@3000000/2000000.pinctrl/gpiochip0/gpio/gpio36#

其中GPIO36的36的由来，32x+y
PA:x=0,PB:x=1,以此类推。那么PB4=321+4

• adb连接
  晕哥的板子有一个usb转ttl的桥，可以用putty进行连接。
  这个板子同时支持adb调试
  1、下载adb工具包
  2、查看是否连接

D:\platform-tools>adb devices
List of devices attached
20080411        device

3、进入板子的shell

D:\platform-tools>adb -s 20080411 shell


BusyBox v1.27.2 () built-in shell (ash)

之前的SDK可能打包缺了文件，试一试我新传的这个：

此处下载：whycanpi_handheld_c3_m2 SDK包

我用这个再加上楼主给的tina2.0_patch_d1s_whycanpic3_20230704a.tar,会报错啊

SDK包太大了，35G这要下载到山崩地裂啊，能不能帮忙上传一个编译器

基于这个SDK

基于这个SDK

编译文件系统和编译app要用同一个gcc就可以了。

这个是编译器还是板子本身的glib版本不一致

是的。
