荔枝派nano的SPI-Flash启动报错（新手入坑求助,4楼有启动的log）
荔枝派Nano公板
SPI_Flash编译烧录启动
交叉编译工具：gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabi
u-boot： nano-lcd800480
Linux：linux-nano-4.14-exp
buildroot：buildroot-2018.11.2
开发环境：ubuntu18.04
TF卡启动是正常得
以下是编译配置以及烧录流程
一、U-boot
修改uboot以适配spi flash
在uboot源码目录下 进入 ./include/configs/，修改 suniv.h
#define CONFIG_BOOTCOMMAND "sf probe 0 50000000; " \
"sf read 0x80C00000 0x100000 0x4000; " \
"sf read 0x80008000 0x110000 0x400000; " \
"bootz 0x80008000 - 0x80C00000"
#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait " \
" mtdparts=spi32766.0:1M(uboot),64k(dtb),4M(kernel),-(rootfs) " \
" root=/dev/mtdblock3 rw rootfstype=jffs2 "Uboot的配置和修改我是参考晕哥的帖子https://whycan.com/t_1623.html
二、Linux
1、Linux配置
勾选 File systems ‣ Miscellaneous filesystems ‣ Journalling Flash File System v2 (JFFS2) support
勾选Device Driver ---> SPI Support ---> Allwinner A31 SPI controller
取消勾选Device Driver ---> SPI Support ---> Allwinner A10 SoCs SPI controller
勾选 Memory Technology Device (MTD) support ---> Caching block device access to MTD devices
勾选 File systems ---> Miscellaneous filesystems ---> Journalling Flash File System v2 (JFFS2) support
取消勾选 Memory Technology Device (MTD) support ---> SPI-NOR device support ---> Use small 4096 B erase
2、修改源码下的 ./drivers/mtd/spi-nor.c
适配spi flash型号
注释掉以下一行:
//{ "w25q128", INFO(0xef4018, 0, 64 * 1024, 256, SECT_4K) },
在这一行下面增加一项:
{ "xt25f128b", INFO(0x064018, 0, 64 * 1024, 256, SECT_4K) },3、修改dts以适配spi flash驱动
修改内核源码目录下的 arch/arm/boot/dts/suniv-f1c100s-licheepi-nano.dts
将原来的&spi0{...}替换为:
&spi0 {
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins_a>;
status = "okay";
spi-max-frequency = <50000000>;
flash: w25q128@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "winbond,xt25f128b", "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <50000000>;
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "u-boot";
reg = <0x000000 0x100000>;
read-only;
};
partition@100000 {
label = "dtb";
reg = <0x100000 0x10000>;
read-only;
};
partition@110000 {
label = "kernel";
reg = <0x110000 0x400000>;
read-only;
};
partition@510000 {
label = "rootfs";
reg = <0x510000 0xAF0000>;
};
};
};
}; dts修改参考荔枝派Nano全流程指南http://nano.lichee.pro/build_sys/build_flash.html#dts
三、Buildroot
下载Buildroot后解压，从零开始编译
配置 make menuconfig
Target options
-- Target Architecture (ARM (little endian))
-- Target Variant arm926t
Toolchain
-- C library (musl) # 使用musl减小最终体积
System configuration
-- Use syslinks to /usr .... # 启用/bin, /sbin, /lib的链接
-- Enable root login # 启用root登录
-- Run a getty after boot # 启用登录密码输入窗口
-- remount root filesystem # 重新挂载根文件系统到可读写
-- Install Timezone info # 安装时区信息。我的程序需要所以就打开了这个玩意
-- timezone list (asia)
-- default local time (Asia/Shanghai)
Target Packages
-- mount/umount # 如果要用overlayfs，那就要用这个挂载最近编辑记录 L_max (2020-12-12 18:23:19)
离线
四、制作系统镜像
将解压后的rootfs，suniv-f1c100s-licheepi-nano.dtb，zImage，u-boot-sunxi-with-spl.bin拷贝到一个文件
1、制作文件系统镜像
//板子自带的16M flashs
执行sudo mkfs.jffs2 -s 0x100 -e 0x10000 -p 0xAF0000 -d rootfs/ -o jffs2.img
会生成jffs2.img
注：
-p 指的是rootfs占据的总空间：16M-1M-64K-4M=0xAF0000 或者 32M-1M-64K-4M=0x1AF0000
-s 页大小0x100 256字节
-e 块大小0x10000 64k
jffs2.img是生成的文件系统镜像。2、编写制作镜像脚本:BuildMyImage.sh
#!/bin/sh
dd if=/dev/zero of=f1c100s_spiflash_16M.bin bs=1M count=16 &&\
dd if=u-boot/u-boot-sunxi-with-spl.bin of=f1c100s_spiflash_16M.bin bs=1K conv=notrunc &&\
dd if=linux/arch/arm/boot/dts/suniv-f1c100s-licheepi-nano.dtb of=f1c100s_spiflash_16M.bin bs=1K see k=1024 conv=notrunc &&\
dd if=linux/arch/arm/boot/zImage of=f1c100s_spiflash_16M.bin bs=1K seek=1088 conv=notrunc &&\
mkfs.jffs2 -s 0x100 -e 0x10000 --pad=0xAF0000 -d rootfs/ -o rootfs.jffs2 &&\
dd if=rootfs.jffs2 of=f1c100s_spiflash_16M.bin bs=1k seek=5184 conv=notrunc &&\
sync注：
①生成一个空文件，大小是16MB
②将uboot添加到文件开头
③将dtb放到1M偏移处
④将kernel放到1M+64K偏移处
⑤将rootfs放到1M+64K+4M偏移处，偏移大小是seek，单位是KB。
执行脚本完毕后生成镜像文件f1c100s_spiflash_16M.bin

五、烧录固件
我是在Ubuntu上用sunxi-fel工具烧录的，sunxi-fel工具安装参考荔枝派Nano全流程指南http://nano.lichee.pro/step_by_step/two_sunxi-tools.html
1、拔出TF卡，上电前， flash的CS和GND短接，不然ubuntu下检测不到Allwinner USB设备，这里我要被自己蠢哭了，CS管脚接错了，我之前接在排针上了，spi0的CS管脚是没有用排针引出来的，需要自己拿根杜邦线引出来，这里又被我们的硬件工程师给坑了，我是想把CS和GND接一个拨动开关，焊接的时候硬件工程师把Nano的GND看错了，一定要看清原理图啊！！！(荔枝派公版排针上的管脚和旁边没用排针引出来的管脚需要看仔细是否是接在一起)
未检测到Allwinner USB设备
sudo sunxi-fel spiflash-info
ERROR: Allwinner USB FEL device not found!2、进入fel就要断开SPI_CE与GND的链接，不然不能读取norflash芯片
sudo sunxi-fel spiflash-info
No SPI flash detected.成功检测到Allwinner USB设备，查看版本信息，显示flash信息
sudo sunxi-fel version
AWUSBFEX soc=00001663(F1C100s) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
sudo sunxi-fel spiflash-info
Manufacturer: Unknown (0Bh), model: 40h, size: 16777216 bytes.3、执行烧录命令烧录,有进度条显示
（虽然进度条从0到100%了，但是不确定有没有烧录成功，请问下怎么样确定烧录成功了呢）
sudo sunxi-fel -p spiflash-write 0 f1c100s_spiflash_16M.bin
100% [================================================] 16777 kB, 79.4 kB/s 4、断电接上串口，上电启动失败，以下是启动log

没有启动运行脚本，他就进入命令行了
能稍微说的详细点嘛？不太明白要怎么解决，谢谢大佬。

增加了U-boot对spi flash的识别
修改uboot源码下的:driver/mtd/spi_flash_ids.c
增加一行

参考大佬LinjieGuo的帖子https://whycan.com/t_3138.html，查看其 menuconfig 配置，发现配置都是有的，还是不清楚自己配置的为啥有问题，可能还是哪里配置错了，忘记把自己的.config贴出来了（内核配置还得自己再配一次）
直接copy大佬的的内核配置文件.config到自己的内核源码中，不修改其它的，重新编译烧录，启动成功了

L_max 说：uuid 说：改用TF卡启动，看下有没有生成 /dev/mtdblockX 分区。
TF卡正常启动，在dev下没有/mtdblockX
ls: /dev/mtdblockX: No such file or directory
那检查 驱动配置和设备树吧，一定要生成 mtdblock设备才行
spi_flash启动OK了，但是在串口终端进入dev下还是没有mtdblock设备

用对比软件对比，linux用meld,diffuse, windows用beyond compare
dev下有mtdblock设备了，谢谢
