请问有没有跟踪应用闪退，并且记录闪退前的日志并且将其输出到log文件的方法

@zm12138 已解决，ts.conf增加
module skip nhead=10 ntail=2

注：需要menuconfig增加相应的插件

@whycanservice # 和这些有关嘛
module pthres pmin=1

module variance delta=30

module dejitter delta=100

module linear

测试触摸屏得时候，点击得时候会有拖拽，怎么解决啊，如视频所示

使用sunxi.c调试触摸屏，使用ts_calibrate校准，使用ts_test测试没有问题，使用ts_uinput -d -v 实例化到event2，执行TSLIB_TSDEVICE=/dev/input/event2 ts_test，测试event2，坐标开始出错，出现负值，LVGL也不可以用了，按照论坛说法，注释#module pthres pmin=1
#module variance delta=30
#module dejitter delta=100
也出现event2坐标出错问题

电阻触摸配置了boarddts，将rtp使能，kernel_menuconfig勾选sunxi 电阻触摸，上电后使用hexdump /dev/input/event0，报错Invalid argument，请问如何解决

回复: T113的linux显示方案

关于eth0的网口自动启动，设置了/etc/network/interfaces
auto eth0
iface eth0 inet dhcp

auto usb0
iface usb0 inet dhcp
实际不能将eth0自启动，请问是怎么回事啊

@xjy_5 root也不行哦

在使用adb传输时候，报如下错误，请问是什么原因啊

@awwwwa 谢谢，已解决

如下日志信息，TF卡外设为SDC0，提示can't find node "mmc0"，请问是哪里出的问题

修改了bootlogo.bmp，将sys_partition.fex里的boot-resource改为880，用PhoenixCard烧录，报错。

为啥Kernel阶段的LCD显示只能显示一半，uboot.dts和board.dts在lcd位置配置是一致的

按照D1-H的音频开发指南配置内置音频接口，出现如下错误，是什么原因啊

@whycan 这些我真的改了，现在搞不明白，目前mmc2和uart0不冲突，为什么mmc2 not
found ,另外内核启动介质是在sys_config.fex里面配的吗？

@whycan 您的意思是我的DTS还是有问题，导致MMC2 not found，对吗

@whycan
感谢，已解决，但是碰到到MMC2 not found的问题，我用的是芒果派，TF是sdc0

小白，问一下挂载点错误，应该修改哪里啊 如下面log错误

@mangogeek 还是报错了

@whycan 大概是刷卡的原因

@mangogeek
好的，学习了

@whycan 改之前是从#ifndef CONFIG_MACH_SUN50IW11
return sdmmc_init_for_sprite(0, 2);，报错，显示没有找到CARD2，我用的是mq芒果派，SD卡是CARD0
#else
改之后是#ifndef CONFIG_MACH_SUN50IW11
return sdmmc_init_for_sprite(0, 0);，报错好像是DTS的错误，但是不知道改哪里

F133启动失败，改过uboot底下的sdmmc.c里面sunxi_sprite_mmc_probe，

#ifndef CONFIG_MACH_SUN50IW11
	return sdmmc_init_for_sprite(0, 2);
#else

无法启动进入内核
