另外我想除了USB烧写方式以外可不可以TF卡烧写，
把生成的bin文件放到TF卡里面，然后用mtd_write，或者dd是否可行，我试了一下目前是没写进去

把这两个参数去掉，并换成4.13y的内核
现在可以启动了，感谢晕哥~

晕哥说：

把这两个参数先去掉: -s 0x100 -e 0x10000

那会不会是我镜像文件生成的有问题，我是这样操作的，（w25q256）
jffs2分区总空间是 32M-1M-64K-4M= 0x1AF0000

mkfs.jffs2 -s 0x100 -e 0x10000 -p 0x1AF0000 -d rootfs/ -o jffs2.img

dd if=/dev/zero of=flashimg.bin bs=32M count=1

感觉我的问题可能出在这
我uboot log，说

SF: Detected w25q256 with page size 256 Bytes, erase size 4 KiB, total 32 MiB
SF: Warning - Only lower 16MiB accessible, Full access #define CONFIG_SPI_FLASH_BAR

另外我的dts是

&spi0 {
	status = "okay";
	
	w25q128:w25q128@0 {
		compatible = "jedec,spi-nor";
		reg = <0x0>;
		spi-max-frequency = <16000000>;
		#address-cells = <1>;
		#size-cells = <1>;
	};
};

晕哥说：

小猪佩奇说：
我只替换了zImage，用的是您发的 V3s_W25Q256_MX25L256_Qt5.9.1.bin 里dd出来的kernel，
内核里这个也选中了<*> Command line partition table parsing
看不出问题了,
有这个log
m25p80 spi0.0: w25q256 (32768 Kbytes)
而没有解析出分区，可能是设备树没有配 spi flash
你把你的 dts 贴出来看下

这是我前几天做的flash镜像，你试一试: v3s_32M_flash.tgz

是的，打错了

Morgan 说：

小猪佩奇说：
原理图设计有36.768k无源晶振，有纽扣电池。
用BSP内核，时间可以保存但是掉电不计时。
求解答
menuconfig选择如下
Set system time from RTC on startup and resume
(rtc0) RTC used to set the system time

*** RTC interfaces ***
/sys/class/rtc/rtcN (sysfs)
/dev/rtcN (character devices)
<*> sunxi rtc driver

看到开始的设计~~不应该是32.768Khz的晶振么~

我使用w25q256，
1. 添加 m25p80 驱动
已添加
2. 设备树添加 spi flash
已添加
3. 内核配置 config commandline parts (也可以配置设备树 dts parts)
已添加
4. bootargs 添加 mtdparts 命令行 (也可以在设备树配置mtdparts)
已添加
5. 用 mkfs.jffs2 制作根文件系统, 并且烧录到前面mtdparts指定的位置.
完全参考看云上的方法做的，https://www.kancloud.cn/lichee/lpi0/331844。

晕哥帮忙看一下~

小猪佩奇 · 全志 SOC

楼主，问题解决了吗，我目前的问题跟你的一样

小猪佩奇 · 全志 SOC

晕哥说：

貌似主线也有这种问题, 而且时间还不准，差很远，后来干脆用PCF8563

确实差得远。。。十分钟内能差两分钟，我得看看晶振了。。

小猪佩奇 · 全志 SOC

Morgan 说：

刚才想到，在V3S钟是有内部晶振，记得第一次都会先使用内部晶振去初始化RTC然后才切换到外部。可以尝试修改驱动直接使用外部晶振，我记得我就是这样解决的~~

感谢，问题已经解决，就是修改了，rtcsunxi.c直接使用外部晶振，掉电也计时了，就是太不准了，十分钟能差两分钟

小猪佩奇 · 全志 SOC

原理图设计有36.768k无源晶振，有纽扣电池。
用BSP内核，时间可以保存但是掉电不计时。
求解答

menuconfig选择如下

Set system time from RTC on startup and resume
(rtc0) RTC used to set the system time

*** RTC interfaces ***
/sys/class/rtc/rtcN (sysfs)

是不是要先在spi_flash_ids.c的const struct spi_flash_info spi_flash_ids[] =中添加w25n01g的相关信息

www220 说：

首先要搞定v3s内置的启动代码如何识别nand，如何读取数据和使用oob，能运行到spl阶段，一切都好办

@emosquito 你好，我也用的W25N01GVZEIG，怎么调的，能否分享一下

emosquito 说：

我试过W25N01GVZEIG，linux下可以读写。把uboot的写到0x00000000开始的1MB，spl没有打印信息。

@qianhao 请问楼主大神，不知道你有没有用BSP内核配置MIPI摄像头？是否成功？我配置完了之后出现

按照这个一样的操作一样的源码：lichee派BSP内核编译教程
编译生成的uImage

晕哥说：

你用的是哪里的源码？
如何编译的？
编译成什么文件了？

小猪佩奇 · 全志 SOC

晕哥，我用的BSP内核，dev下也没有 graphics

晕哥说：

camdroid照搬了android的framework,
所以fb0也搬家到了 /dev/graphics/fb0

小猪佩奇 · 全志 SOC

我在编译内核打开了framebuffer驱动，使内核支持了framebuffer驱动，但是开发板启动后在/dev下找不与fb相关的东西，通过cat /proc/devices能够看到29 fb,在/proc下也能看到fb，但是/dev下就是没有fb0设备，用mknod /dev/fb0 c 29 0建立了fb0但是cat /dev/fb0却提示can't open /dev/fb0 no such device.
求大神路过~

小猪佩奇 · 全志 SOC

你用的是什么接口的摄像头？
我看v4L2是针对uvc免驱usb设备的编程框架，主要用于采集usb摄像头？MIPI的不知道可以吗

daydayup 说：

我试过camdroid,用v4l2标准接口获取数据即可。

小猪佩奇 · 全志 SOC

v3s上测试MIPI接口摄像头安装什么软件比较好~我看有fswebcam, 路过的大神有没有推荐和安装教程？

小猪佩奇 · 全志 SOC

会不会跟内核的配置有关，如果会，那么可能是内核哪里配置出问题

晕哥说：

建议先用 ramdisk, 就是根文件系统与 kernel一起打包那种方式，
先把系统跑起来，
然后插卡，
看系统是否能挂载 mmcblk0p2 的文件系统。

小猪佩奇 · 全志 SOC

我只是把卡的第一分区拷入配置好的script.bin ,uImage ,boot.scr

小猪佩奇 · 全志 SOC

晕哥，是这样的
同样的卡，同样的文件系统，主线linux正常启动

晕哥说：

基于上面那些问题，建议还是先烧一个能跑起来的系统吧，然后插卡，看卡是否正常。

小猪佩奇 · 全志 SOC

求大神路过
BSP启动内核卡在这里是什么问题

我的根文件系统运行主线Linux没问题

晕哥赶快录入坑视频吧，我现在考虑出坑，追随海豚派了~捂脸

晕哥说：

那你在 u-boot里面看下i2c有没有驱动，如果驱动了直接调用接口读写 AXP152.
不过我还是强烈建议玩海豚派这种和官方SDK，
海豚派有完整的spi nand支持，AXP203 mpu, ESP8089 wifi等。
别玩主线了，早日出坑。
主线上面很多外设都不支持。

小猪佩奇 · 全志 SOC

我的板子是有三路电压默认值跟我所需要的电压值不对，用i2ctools可以读写，但是我应该在uboot里面直接把默认电压给改了才对吧，不知道晕哥有没有什么办法~

晕哥说：

不用客气，有不明白的，可以跟帖提出哦
我买的海豚派开发板自带 AXP203,

晕哥说：

小猪佩奇说：
你当时设置过电源芯片的某通道的电压么，我知道是写寄存器，但是不知道在哪写
应用层测试可以用i2c-tools工具写, 通过 /dev/i2c-0 这个接口与 i2c设备通讯.
照着axp152手册直接读写寄存器, 可以控制电压和axp152 的GPIO口。
